• Essay on Computer

Long and Short Computer Essay

The term computer was once used to refer to a person who did computation, unlike today. The development of early prototypes that led to the modern computer is credited to many individuals throughout history. A series of breakthroughs, beginning with transistor computers and then integrated circuit computers, resulted in the development of transistor technology and the integrated circuit chip, causing digital computers to largely replace analogue computers. 

In this essay, we will discuss the various components and types of computers and talk about their uses in various fields.

Long Computer Essay in English

A computer is an electronic tool that manipulates data or information. It can store, retrieve, and process information. We can type documents, send emails, play games, and browse the Web using a computer. It can also be used to edit spreadsheets, presentations, and even videos, or create them. 

Early computers were conceived only as devices for calculating. Simple manual devices such as the abacus have helped individuals do calculations since ancient times. Some mechanical devices were built early in the Industrial Revolution to automate long, tedious tasks, such as guiding patterns for looms. In the early 20th century, more sophisticated electrical machines performed specialized analogue calculations. 

Common Components of Computers

All those parts of a computer that are tangible physical objects are covered under the term hardware. The hardware includes circuits, computer chips, graphics cards, sound cards, memory (RAM), motherboards, displays, power supplies, cables, keyboards, printers and "mice" input devices.

 There are five main hardware components: 

Input Devices: 

These are devices that are used to enter data/information in the central processing unit. Example- keyboard, mouse, scanner, document reader, barcode reader, optical character reader, magnetic reader etc.

Output Devices: 

These are devices that provide the processed data/information into human-readable form. Example- monitor, printer, speaker, projector etc.

Control Unit: 

The control unit handles the various components of the computer; it reads and interprets (decodes) the instructions for the program, transforming them into control signals that activate other computer parts.

Arithmetic Logic Unit: 

It is capable of performing arithmetical and logical functions. The set of arithmetic operations supported by a specific ALU may be restricted to addition and subtraction or may include functions of multiplication, division, trigonometries such as sine, cosine, etc., and square roots.

Central Processing Unit: 

The ALU, control unit and registers and together called the CPU. It is sometimes called the computer's brain, and its job is to perform commands. We send instructions to the CPU whenever we press a key, click the mouse, or start an application.

Software refers to computer parts, such as programs, data, protocols, etc., that do not have a material form. In contrast to the physical hardware from which the system is built, the software is that portion of a computer system consisting of encoded information or computer instructions.

It is sometimes called "firmware" when the software is stored in hardware that can not be easily modified, such as with a BIOS ROM on an IBM PC compatible computer.

Computer hardware and software require each other, and neither of them can be realistically used on their own. There are four main components of a general-purpose computer: the arithmetic logic unit (ALU), the control unit, the memory, and the I/O (collectively called input and output) devices.

Uses of Computer

Computers are used in various fields, such as homes, businesses, government offices, research organizations, educational institutions, medicine, entertainment, etc. because of their features and powerful functions. They have taken sectors and companies to a whole new level.

Science- 

Computers are best suited for the collection, analysis, categorization, and storage of data in science, research and engineering. They also help scientists to exchange data both internally and internationally with each other.

Government-  

Computers in the government sector are used to perform various functions and improve their services. In most cases, data processing tasks, the maintenance of citizens' databases, and the promotion of a paperless environment are the primary purposes of using computers. In addition to this, computers play a key role in the country's defence system.

Health and Medicine- 

They are used to preserve information, records, live patient monitoring, X-rays, and more from patients. Computers assist in setting up laboratory tools, monitoring heart rate and blood pressure, etc. Besides, computers allow physicians to easily exchange patient data with other medical specialists.

Education- 

They help people get different educational materials (such as images, videos, e-books, etc.) in one place. Also, computers are best suited for online classes, online tutoring, online exams, and task and project creation. Also, they can be used to maintain and track student performance and other data.

Banking- 

Most countries use online banking systems so that customers can access their data directly. People can verify the balance of their account, transfer cash, and pay online bills, including credit cards. Besides, banks use computers to execute transactions and store client information, transaction records, etc.

Short Computer Essay in English

A computer's a programmable device that accepts raw data(input) and processes it as output with a group of instructions (a program) to supply the result. It renders output after performing mathematical and logical operations and can save the output for future use. The word "computer" derives from the word "computare" in Latin, which means calculating.

Types of Computer

Computers are of different types based on different criteria. Based on their size, computers are of five types:

Micro Computers- 

It is a single-user computer that has less capacity for speed and storage than the other types. For a CPU, it uses a microprocessor. Laptops, desktop computers, personal digital assistants (PDAs), tablets, and smartphones are common examples of microcomputers. Microcomputers are generally designed and built for general use, such as browsing, information search, the internet, MS Office, social media, etc.

Mini Computers- 

Minicomputers are also referred to as "Midrange Computers." They are multi-user computers designed to simultaneously support multiple users. Therefore, they are generally used by small companies and firms. 

Mainframe Computers- 

It is also a multi-user computer that large companies and government organizations use to run their business operations as large amounts of data can be stored and processed. Banks, universities, and insurance companies, for example, use mainframe computers to store data from their customers, students, and policyholders.

Super Computer- 

Among all types of computers, supercomputers are the fastest and most costly computers. They have an enormous capacity for storage and computing speeds and can therefore perform millions of instructions per second.

Workstations-  

It is a single-user computer with a comparatively more powerful microprocessor and a high-quality monitor compared to a mini-computer.

Benefits of Computers:

It increases productivity.

It helps in connecting to the internet.

It helps in organizing data and information.

It allows storing large amounts of data.

Fun Facts About Computers

The first electric computer that was invented weighed around 27 tons or even more than that and took up to 1800 square feet.

There are about 5000 new viruses that are released every month.

The original name of Windows was Interface Manager.

It is surely known that the life of humans would not have been so easy if computers were not a part of human life. This is also supported by a lot of pieces of evidence where we can even see in daily life how the computer is not just present in an organization but is also available right in the pockets of everyone. Thus, the computer has surely made it easy while also spoiling a lot of people's lives. 

FAQs on Essay on Computer

1. What are the disadvantages of computers?

While the computer has surely made life easier, it also has a lot of disadvantages. The disadvantages of the computers can be provided as follows:

People spend too much time sitting and doing nothing but watching the content on computers.

People staring at computers for a long time also tend to strain their eyes, and as a result, they need spectacles to understand what is being written in front of them.

Attention span is decreasing with an increase in the use of computers. 

With computers being AI-powered, it is now easier for people to do all the tasks on a computer and not work on it themselves. This has made a lot of people lazy.

2. What is the process of working on a computer?

A computer is an electronic machine and it needs information to be added in as raw data to function well. It has a flow that determines the accessing of data. The following steps take place before the results are obtained:

Information is taken in by the computer in the form of raw data. This process is also called the input.

Then the information that is not needed will be stored while the information that is needed is passed onto the next step. The storing of data is called memory.

Then the information that is required is crushed or it is split and this process is called processing.

The last step is where the results are obtained. This process is called getting the output.

A complex set of processes, calculations, and operations performs everything we do on a computer. Without a doubt, computers make our lives easier and enhance our personal and working life.

5 Top Essay Examples

1. types of computers by brent dawson, 2. uses of computers in education by kristina barroso, 3. our dependency on computers by nora fox, 4. neural networks: is your brain like a computer by shamli prakash.

• 5. ​​The Human Brain vs. Supercomputers… Which One Wins? By John Staughton

1. The Many Uses of Computers

2. can computers take over society, 3. is computer science a worthwhile program to study, 4. pros and cons of computers, 5. can computers compete with the human brain.

“Calculations for things such as automotive design, weather forecasting, and aerospace use supercomputers. Embedded computers are used for functions in a larger product. They are located in things such as automobiles, consumer electronics and office machines. As we all know computers come in many shapes and sizes. They can be used for many different things and can be located anywhere. Technology has increased so much that the most unheard compact thing can be a computer.

Dawson stresses that computers can come in all shapes and sizes. There are different types of computers, such as personal computers, mobile computers, game consoles, and supercomputers, each with its own functions and specialties. He briefly touches on each type of computer and its uses. Technology has come a long way, as the most complex computers are everywhere, whether in laboratories, offices, or even our mobile phones or watches. 

“Critics argue that spell check and other computer features that automatically correct errors in spelling and punctuation make students too lazy to learn and apply the rules themselves. These features, however, help point out where students went wrong and offer valuable learning opportunities that can help students enhance their understanding of appropriate spelling and punctuation.”

In her essay, Barroso discusses the advantages and disadvantages of incorporating computers into education. They allow schools to maximize online resources, foster student engagement, and make it easier for teachers and students to perform school-related tasks. However, they may make students lazy to check mistakes, thinking that the computers will automatically check them. Ultimately, the pros outweigh the cons. 

“As far as I concerned, computer is a great invention and it is useful to human life. It should be impossible to live without computer as we get too much used of computers nowadays. However, we should use it wisely. We know the fact that the more we rely on computer, the more we will lose in our life. So, we should also find ways to make our dependence on computers less dangerous to us, so that we will not rely on computer completely.”

Fox discusses the state of society today where we rely far too much on computers. They help us greatly in our daily lives, but they have made us depend on technology for information rather than thinking for ourselves. And if something goes wrong, like the servers crash, the world is at a standstill. Computers are a net good for society, but we must avoid revolving our lives around technology. 

“In data science terms, this phase is somewhat akin to ‘Model Training’ — the more things a child is exposed to the more the synapses associated with it get built. A good example is language — the more a child is exposed to linguistics in early years, the more evolved the area of her brain that is associated with languages would get. Ditto for other cognitive and non-cognitive abilities.”

Prakash discusses the different ways in which our brains operate as computers. An information processing system has five components: input, output, storage, processing, and program. The human brain does have all of these components, which are used to perform our daily functions. She looks into how human intelligence can be “trained,” like computers are developed. 

5. ​​ The Human Brain vs. Supercomputers… Which One Wins? By John Staughton

“When the brain identifies a more efficient or effective way to compute and function, it can morph and alter its physical and neuronal structure, hence the term “plasticity“. Until we achieve true Artificial Intelligence (in which computers should theoretically be able to re-wire themselves), neuroplasticity will always keep the human brain at least one step ahead of “static” supercomputers.”

Staughton writes about how much more advanced computers have become in recent decades, with some of them being able to outsmart humans in tasks such as chess. However, he explains that our brains are very different from technology and are inherently superior to even the most powerful computers in terms of efficiency, adaptability, and many other factors. However, he keeps the door on computers, eventually developing beyond our capabilities in the future.

This is a question many have grappled with and is the subject of many science-fiction and dystopian stories. Many believe that only good can come from greater technological advancement, while others believe humanity will be subject to much conflict and suffering. Based on research, decide whether we should introduce computers into more aspects of our lives. You can cite articles, essays, books, or even movies to prove your point. 

In your essay, discuss how helpful an education in computer science would be. Research the course’s requirements, benefits, disadvantages, and expectations and, based on your personal opinion, write about whether it would be worth it to pursue this program. This essay is more suited for those with experience, but if not, consult online sources or interview people with experience for a solid evidence base.

Computers have many advantages as well as disadvantages. List down the pros and cons of computers you can come up with, and discuss a few of them in your essay. Then, based on the evidence you’ve provided, decide whether computers are a net good or bad for society in the long run. 

A few essay examples above have compared technology and artificial intelligence to the human brain, as they are both “computers,” so to speak. In your opinion, will technology ever come to a point where it will rival our abilities? Conduct research and cite credible sources for a strong essay .

साथ ही, कक्षा 1 से 10 तक के छात्र उदाहरणों के साथ इस पृष्ठ से विभिन्न हिंदी निबंध विषय पा सकते हैं।

कंप्यूटर की उपयोगिता पर निबंध – Kampyootar Ki Upyogita Par Nibandh

प्रस्तावना– गत हजार वर्षों में विज्ञान ने मानव जीवन को पूर्णत: परिवर्तित कर दिया है। परन्तु इन हजार वर्षों में से जितना परिवर्तन पहले 900 वर्ष में नहीं हो पाया था जितना परिवर्तन केवल अन्तिम 100 वर्षों में हो गया। इसी प्रकार पूर्ण बीसवीं शताब्दी में जो विकास और परिवर्तन उपस्थित हुए हैं उनमें से अन्तिम दशक में हुए परिवर्तन ही अधिक महत्त्वपूर्ण हैं। अभिप्राय यह है कि विज्ञान के विकास की गति तीव्र से तीव्रतर होती जा रही है। पिछले सौ वर्ष में वैज्ञानिक अनुसंधानों और आविष्कारों में सबसे अधिक महत्त्वपूर्ण योगदान कम्प्यूटर का ही है।

पिछले कुछ वर्षों में तो इस यन्त्र का उपयोग जीवन के प्रत्येक क्षेत्र में इतना अधिक हो गया है कि किसी भी प्रयोगशाला, उद्योग, अनुसंधान केन्द्र यहाँ तक कि आधुनिक कार्यालय और विभाग के कम्प्यूटर विहीन होने की कल्पना ही नहीं की जा सकती। – कम्प्यूटर का परिचय–वैसे तो आधुनिक कम्प्यूटर की योजना चार्ल्स बैबेज (1792–1871) ने की थी परन्तु इसका उल्लेखनीय उपयोग सबसे पहले अमेरिका के विद्वान हरमान होल्लेरिथ ने किया था। इनके बाद कम्प्यूटर को पहली बार द्वितीय विश्वयुद्ध के समय बिजली से चलाने की कला का विकास हुआ।

विकास करते– करते आधुनिक रूप में कम्प्यूटर एक बहु–आयामी और बहु–उपयोगी यन्त्र बन चुका है। कम्प्यूटर एक ऐसा यन्त्र है जिसमें गणित सम्बन्धी सूत्रों तथा विभिन्न तथ्यों को सूत्र रूप में भर दिया जाता है और जो आशातीत गति से विभिन्न समस्याओं और गणनाओं को सुलझा सकने में समर्थ है। कभी–कभी मानव द्वारा बनाये गये इस यन्त्र की कार्यक्षमता एवं तीव्र गति को देखकर आश्चर्य होता है।

सार्वजनिक क्षेत्रों में कम्प्यूटर के उपयोग–वैसे तो कम्प्यूटर अब धीरे–धीरे हमारे जीवन के सभी क्षेत्रों में प्रवेश करता जा रहा है। हम अपनी विभिन्न गतिविधियों के लिए कम्प्यूटर पर अधिक–से–अधिक आश्रित होते जा रहे हैं, फिर भी सुविधा के लिए इसके विभिन्न सार्वजनिक क्षेत्रों में उपयोग का विस्तार से अध्ययन कर लेना अच्छा रहेगा।

1. गणना एवं सूचना–संग्रह (बैंकिंग आदि)–अब तक बैंकों में खातों का हिसाब रखने का काम लिपिकों द्वारा खाता पृष्ठों पर किया जाता था परन्तु अब खाता पृष्ठों और किताबों के बनाने और सुरक्षित रखने की आवश्यकता नहीं है। अब इन्हें कम्प्यूटरों में भर कर सुरक्षित भी रखा जा सकता है और उनमें गणनाएँ भी तीव्रता से की जा सकती हैं। कम्प्यूटर की इस क्षमता का उपयोग कर बड़ी–बड़ी परीक्षा संस्थाओं (जैसे यू०पी० बोर्ड एवं विश्वविद्यालय आदि) परीक्षा–फल थोड़े ही समय में तैयार किये जा सकते हैं। गणनाओं के संचय और उपयोग की क्षमता से ही अब चूनाव परिणामों को कम्प्यूटरीकृत मशीनों द्वारा अल्पकाल में ही प्राप्त किया जा सकता है।

2. सूचना तकनीक के क्षेत्र में अब कम्प्यूटर द्वारा देश–विदेश की सूचनाओं को तीव्रगति से प्रेषित एवं संकलित किया जा सकता है। अन्तरिक्ष यानों एवं उपग्रहों में स्थापित विभिन्न अनुसंधान संयन्त्रों द्वारा प्रेषित बड़ी–बड़ी सूचनाएं एवं गणनाएं अब क्षणों में एक स्थान से दूसरे स्थान को प्रेषित की जा रही हैं। पूर्व रेलवे आरक्षण एवं वायुयान आरक्षण भी इसी कारण सम्भव हो सके हैं। इन्टरनेट, ईकॉम, ईमेल और फैक्स मशीनों में भी कम्प्यूटर का उपयोग होता है।

3. मुद्रण एवं प्रकाशन कम्प्यूटर द्वारा संचालित फोटो कम्पोजिंग मशीन ने पत्र–पत्रिकाओं और पुस्तक प्रकाशन के कार्य को तीव्रगति एवं सुविधा प्रदान की है। पहले छापेखानों में एक–एक अक्षर का टाइप एकत्र कर जो कम्पोजिंग किया जाता था अब उसकी आवश्यकता नहीं रही है। अब तो चुम्बकीय डिस्क में सामग्री भर कर उसका क्षणों में कम्पोजिंग और मुद्रण हो जाता है। गणनाएँ और अक्षर ही नहीं, अब कम्प्यूटर द्वारा चित्रों आदि की छपायी भी सरल हो गयी है। यही कारण है कि पहले जिन पुस्तकों और पत्रिकाओं को प्रकाशित होने में बहुत–सा समय व्यय हो जाता था अब वह प्रकाशन अपेक्षाकृत अल्पकाल में ही सम्भव हो गया है।

4. कला, संगीत एवं डिजाइनिंग के क्षेत्र में कम्प्यूटर अब गणना और स्मृति के लिए ही नहीं, कला, संगीत और डिजाइनिंग के क्षेत्र में भी मनुष्य को सहयोग दे रहा है। कलाकार कम्प्यूटर की सहायता से अपने चित्र, डिजाइन और स्वरों तक का उचित समायोजन कर सकते हैं।

5. वैज्ञानिक अनुसंधान एवं खोज–कम्प्यूटरों की सहायता से विभिन्न प्रयोगशालाओं और वेधशालाओं में वैज्ञानिक अनुसंधान किये जा रहे हैं। अब गणनाओं और परिणामों को अपेक्षाकृत अधिक शुद्ध रूप से और तीव्रगति से प्राप्त किया जा सकता है। वैज्ञानिक उत्पादन एवं विभिन्न उद्योग–धन्धों में भी इसके उपयोग से हम लाभान्वित हो रहे हैं।

6. युद्ध के क्षेत्र में पहले विद्युतीकृत कम्प्यूटर का प्रयोग अमेरिका ने अणुबम के विस्फोट सम्बन्धी गणनाओं के लिए किया था। अब अन्तरिक्ष अनुसंधानों, मिसाइलों, रडार और सूक्ष्मातिसूक्ष्म यन्त्रों और उपकरणों का इस प्रकार कम्प्यूटरीकरण हो गया है कि अब लगने लगा है कि भविष्य के युद्धों में कम्प्यूटरों की अहम् भूमिका रहेगी। . कम्प्यूटर एवं मानव–अब सरकारें, बड़ी–बड़ी व्यावसायिक एवं औद्योगिक संस्थाएँ और अनुसंधान केन्द्र ही नहीं प्रत्येक सम्पन्न व्यक्ति कम्प्यूटर को अपने व्यक्तिगत सहायक के रूप में रखने का इच्छुक है।

मानव की कम्प्यूटर पर बढ़ती आश्रितता को देखकर कभी–कभी मनुष्य अपने द्वारा बनाये गये इस यन्त्र को मनुष्य से अधिक उपयोगी और महत्त्वपूर्ण समझने लगता है, परन्तु वह भूल जाता है कि मानव द्वारा निर्मित इस उपकरण में मनुष्य की अपेक्षा अनेक दोष हैं। इसमें अनुभूति और उस पर आधारित सद्भावों का अभाव है। वह बिना संचालक के अपंग है उसमें अन्त: प्रेरणा एवं स्वयं निर्णय का मानवोचित गुण नहीं है।

उपसंहार– हमारे देश में कम्प्यूटर क्रान्ति लाने का श्रेय हमारे पूर्व प्रधानमंत्री श्री राजीव गांधी को है। समान्य जानकारियों के अतिरिक्त भविष्य में कम्प्यूटर विवाह हेतु जोड़े तैयार करेगा फिर भी हर वैज्ञानिक अनुसंधान की भाँति कम्प्यूटर के अनुचित प्रयोग का खतरा वर्तमान है और क्योंकि कम्प्यूटर का क्षेत्र और कार्यक्षमता अधिक है, अत: इसके खतरे भी असीम हैं।

गणना अथवा उपयोग की जरा सी ही त्रुटि सम्पूर्ण मानवता का विनाश करने में सक्षम है। भारत जैसे जनबहुल देश में तो इससे बेरोजगारी बढ़ने का खतरा भी भयंकर ही है अनेक दोष होते हुए भी सार्वजनिक क्षेत्रों में इसके महत्त्व को नकारा नहीं जा सकता, समाज में कम्प्यूटर ने अपनी महत्ता एवं उपयोगिता अल्पसमय में ही स्थायी रूप से स्थापित कर ली है।

How Computers Affect Our Lives Essay

How computers affect our lives: essay introduction.

Computers are a common phenomenon in the lives of people in today’s world. Computers are very vital especially to those people who run businesses, industries and other organizations. Today, almost everything that people engage in makes use of a computer. Take for instance, the transport sector: vehicles, trains, airplanes, and even traffic lights on our roads are controlled by computers.

In hospitals, most of the equipments use or are run by computers. Look at space exploration; it was all made possible with the advent of computer technology. In the job sector, many of the jobs require knowledge in computers because they mostly involve the use of computers.

In short, these machines have become so important and embedded in the lives of humans, they have hugely impacted on the whole society to the extent that it will be very hard to survive now, without them. This article discusses the influence of computers on the everyday life of human beings.

One can guess what will exactly happen if the world had no computers. Many of the cures found with help of computer technology would not have been developed without computer technology, meaning that many people would have died from diseases that are now curable. In the entertainment industry, many of the movies and even songs will not be in use without computers because most of the graphics used and the animations we see are only possible with the help of a computer (Saimo 1).

In the field of medicine, pharmacies, will find it hard in determining the type of medication to give to the many patients. Computers have also played a role in the development of democracy in the world. Today votes are counted using computers and this has greatly reduced incidences of vote rigging and consequently reduced conflicts that would otherwise arise from the same.

And as we have already seen, no one would have known anything about space because space explorations become possible only with the help of computer technology. However, the use of computers has generated public discourses whereby people have emerged with different views, some supporting their use and others criticizing them (Saimo 1).

History of computers

To better understand how computers influence the lives of people, we will have to start from the history, from their invention to the present day. Early computers did not involve complex technologies as the ones that are used today; neither did they employ the use of monitors or chips that are common today.

The early computers were not that small as those used today and they were commonly used to help in working out complex calculations in mathematics that proved tedious to be done manually. This is why the first machine was called by some as a calculator and others as a computer because it was used for making calculations.

Blaise Pascal is credited with the first digital machine that could add and subtract. Many versions of calculators and computers borrowed from his ideas. And as time went by, many developed more needs, which lead to modifications to bring about new and more efficient computers (Edwards 4).

Positive Effects of Computer on Human Life

Computer influence in the life of man became widely felt during World War II where computers were used to calculate and track the movements and also strategize the way military attacks were done (Edwards 4). It is therefore clear, that computers and its influence on man have a long history.

Its invention involved hard work dedication and determination, and in the end it paid off. The world was and is still being changed by computers. Man has been able to see into the future and plan ahead because of computers. Life today has been made easier with the help of computers, although some people may disagree with this, but am sure many will agree with me.

Those who disagree say that computers have taken away the role of man, which is not wrong at all, but we must also acknowledge the fact what was seen as impossible initially, become possible because of computers (Turkle 22).

As we mentioned in the introduction, computers are useful in the running of the affairs of many companies today. Companies nowadays use a lot of data that can only be securely stored with the help of computers. This data is then used in operations that are computer run. Without computers companies will find it difficult store thousands of records that are made on a daily basis.

Take for instance, what will happen to a customer checking his or her balance, or one who just want to have information on transactions made. In such a case, it will take long to go through all the transactions to get a particular one.

The invention of computers made this easier; bank employees today give customers their balances, transaction information, and other services just by tapping the computer keyboard. This would not be possible without computers (Saimo 1).

In personal life

Today individuals can store all information be it personal or that of a business nature in a computer. It is even made better by being able to make frequent updates and modifications to the information. This same information can be easily retrieved whenever it is needed by sending it via email or by printing it.

All this have been made possible with the use of computers. Life is easier and enjoyable, individuals now can comfortably entertain themselves at home by watching TV with their families or they can work from the comfort of their home thanks to computer technology.

Computers feature in the everyday life of people. Today one can use a computer even without being aware of it: people use their credit cards when buying items from stores; this has become a common practice that few know that the transaction is processed through computer technology.

It is the computer which process customer information that is fed to it through the credit card, it detects the transaction, and it then pays the bill by subtracting the amount from the credit card. Getting cash has also been made easier and faster, an individual simply walks to an ATM machine to withdraw any amount of cash he requires. ATM machines operate using computer technology (Saimo 1).

I mentioned the use of credit cards as one of the practical benefits of using computers. Today, individual do not need to physically visit shopping stores to buy items. All one needs is to be connected on the internet and by using a computer one can pay for items using the credit card.

These can then be delivered at the door step. The era where people used to queue in crowded stores to buy items, or wasting time in line waiting to buy tickets is over. Today, travelers can buy tickets and make travel arrangements via the internet at any time thanks to the advent of computer technology (Saimo 1).

In communication

Through the computer, man now has the most effective means of communication. The internet has made the world a global village. Today people carry with them phones, which are basically small computers, others carry laptops, all these have made the internet most effective and affordable medium of communication for people to contact their friends, their families, contact business people, from anywhere in the world.

Businesses are using computer technology to keep records and track their accounts and the flow of money (Lee 1). In the area of entertainment, computers have not been left behind either.

Action and science fiction movies use computers to incorporated visual effects that make them look real. Computer games, a common entertainer especially to teenagers, have been made more entertaining with the use of advanced computer technology (Frisicaro et.al 1).

In Education

The education sector has also been greatly influenced by computer technology. Much of the school work is done with the aid of a computer. If students are given assignments all they have to do is search for the solution on the internet using Google. The assignments can then be neatly presented thanks to computer software that is made specifically for such purposes.

Today most high schools have made it mandatory for students to type out their work before presenting it for marking. This is made possible through computers. Teachers have also found computer technology very useful as they can use it to track student performance. They use computers to give out instructions.

Computers have also made online learning possible. Today teachers and students do not need to be physically present in class in order to be taught. Online teaching has allowed students to attend class from any place at any time without any inconveniences (Computers 1).

In the medical sector

Another very crucial sector in the life of man that computers has greatly influenced and continues to influence is the health sector. It was already mentioned in the introduction that hospitals and pharmacies employ the use of computers in serving people.

Computers are used in pharmacies to help pharmacists determine what type and amount of medication patients should get. Patient data and their health progress are recorded using computers in many hospitals. The issue of equipment status and placement in hospitals is recorded and tracked down using computers.

Research done by scientists, doctors, and many other people in the search to find cures for many diseases and medical complications is facilitated through computer technology. Many of the diseases that were known to be dangerous such as malaria are now treatable thanks to computer interventions (Parkin 615).

Computers replacing man

Many of the opponents of computer technology have argued against the use of computers basing their arguments on the fact that computers are replacing man when carrying out the basic activities that are naturally human in nature.

However, it should be noted that there are situations that call for extraordinary interventions. In many industries, machines have replaced human labor. Use of machines is usually very cheap when compared to human labor.

In addition machines give consistent results in terms of quality. There are other instances where the skills needed to perform a certain task are too high for an ordinary person to do. This is usually experienced in cases of surgery where man’s intervention alone is not sufficient. However, machines that are computer operated have made complex surgeries successful.

There are also cases where the tasks that are to be performed may be too dangerous for a normal human being. Such situations have been experienced during disasters such as people being trapped underground during mining. It is usually dangerous to use people in such situations, and even where people are used, the rescue is usually delayed.

Robotic machines that are computer operated have always helped in such situations and people have been saved. It is not also possible to send people in space duration space explorations, but computer machines such as robots have been effectively used to make exploration outside our world (Gupta 1).

Negative Computer Influences

Despite all these good things that computers have done to humans, their opponents also have some vital points that should not just be ignored. There are many things that computers do leaving many people wondering whether they are really helping the society, or they are just being used to deprive man his God given ability to function according to societal ethics.

Take for instance in the workplace and even at home; computers have permeated in every activity done by an individual thereby compromising personal privacy. Computers have been used to expose people to unauthorized access to personal information. There is some personal information, which if exposed can impact negatively to someone’s life.

Today the world does not care about ethics to the extent that it is very difficulty for one to clearly differentiate between what is and is not authentic or trustful. Computers have taken up every aspect of human life, from house chores in the home to practices carried out in the social spheres.

This has seen people lose their human element to machines. Industries and organizations have replaced human labor for the cheap and more effective machine labor. This means that people have lost jobs thanks to the advances made in the computer technology. Children using computers grow up with difficulties of differentiating between reality and fiction (Subrahmanyam et.al 139).

People depend on computers to do tasks. Students generate solutions to assignments using computers; teachers on the other hand use computers to mark assignments. Doctors in hospitals depend on machines to make patient diagnoses, to perform surgeries and to determine type of medications (Daley 56).

In the entertainment industry, computer technology has been used to modify sound to make people think that person singing is indeed great, but the truth of the matter is that it is simply the computer. This has taken away the really function of a musician in the music sector.

In the world of technology today, we live as a worried lot. The issue of hacking is very common and even statistics confirm that huge amounts of money are lost every year through hacking. Therefore, as much as people pride themselves that they are computer literate, they deeply worried that they may be the next victim to practices such as hacking (Bynum 1).

Conflict with religious beliefs

There is also the problem of trying to imitate God. It is believed that in 20 years time, man will come up with another form of life, a man made being. This will not only affect how man will be viewed in terms of his intelligence, but it will also break the long held view that God is the sole provider of life.

Computers have made it possible to create artificial intelligence where machines are given artificial intelligence so that they can behave and act like man. This when viewed from the religious point of view creates conflicts in human beliefs.

It has been long held that man was created in the image of God. Creating a machine in the image of money will distort the way people conceive of God. Using artificial methods to come up with new forms of life with man like intelligence will make man equate himself to God.

This carries the risk of changing the beliefs that mankind has held for millions of years. If this happens, the very computer technology will help by the use of mass media to distribute and convince people to change their beliefs and conceptions of God (Krasnogor 1).

Conclusion: How Computer Influences Our Life

We have seen that computer have and will continue to influence our lives. The advent of the computers has changed man as much as it has the world he lives in.

It is true that many of the things that seemed impossible have been made possible with computer technology. Medical technologies have led to discoveries in medicine, which have in turn saved many lives. Communication is now easy and fast. The world has been transformed into a virtual village.

Computers have made education accessible to all. In the entertainment sector, people are more satisfied. Crime surveillance is better and effective. However, we should be ware not to imitate God. As much as computers have positively influenced our lives, it is a live bomb that is waiting to explode.

We should tread carefully not to be overwhelmed by its sophistication (Computers 1). Many technologies have come with intensities that have seen them surpass their productivity levels thereby destroying themselves in the process. This seems like one such technology.
