Everyone using PCs now days. But understanding advantages and disadvantages of computers is very important. This is a complete guide to computer’s pros and cons, which will help you understand- how to use a laptop or computer properly?
Students of various classes can use this article to write a good essay on computers.
Introduction on Computers
A computer is a device that receives information from a source, processes it, and delivers processed data to a destination. In today’s world, every mechanism requires the use of computers. Thinking about age without computers is now hard.
We use computers in almost every department. Whether medicine, teaching, defense, finance, computer’s use is enormous. We also automate many functions awkward for people using computers and well-developed technology.
Initially, the computers were large and stored only less data, but in upcoming technology has invented much smaller and more comfortable to use and capable of storing more information.
The Basic Units of Computers
- Input unit
- Central processing unit
- Output unit
These units are defined as below:
1. The Input unit
As the name implies, this device with which data enter the computer. This device is an essential requirement for a computer system.
Input devices are many types, such as a keyboard, a mouse, joystick, a microphone, a camera. Input devices give a different set of input values converted into a computer-understandable form.
Central Processing Unit (CPU) is known as the brain of the computer. It performs all data processing operations required by the programmer.
It stores all data, intermediate results, and instructions provided by the programmer as codes (program). The central processing unit controls the operation of each part of the computer.
2. Central processing unit (CPU)
It comprises the following three elements:
- An arithmetic unit
- Memory unit
- Control unit
3. Output unit
The devices with which we obtain information from a computer are called output devices. The output unit is the interface between the computer and the user.
Output devices notify the displayed information in a form understandable to the computer user.
Features of Computers
- Data enters the computer via input devices.
- Data or instructions are stored on a computer in its memory and processed or used when needed.
- The input data process and transform into useful information.
- The output generated by format.
- The control mechanisms established to control all functions.
Further, we can divide the computer into hardware and software:
Keyboard, mouse, joystick, microphone, camera, printer, monitor, hard disk, CD, DVD, processor, motherboard, RAM, etc. They are called hardware equipment.
System software like window and application software like MS office, flash player, .rar file opener, etc. are software that requires working on the computer.
Although we use computers in many areas, there are many pros and cons when using computers. In this essay, we will discuss the pros and cons of using computers as well.
Advantages and Disadvantages of Computers (New Updated 2021)
Advantages of Computers
Computers are widely used in many areas because they can quickly process large amounts of data in a short time. They are also known for performing tasks more efficiently, and there is minimal possibility of errors.
It can perform complex functions and complete them in a few seconds. When some jobs are troublesome for people, computers can do them quickly.
Some advantages of computers are:
1. Best Data Storage Device
Computers store a large amount of data, and we can easily search for it. Data can also be found in minimal time. However, when we store data in files or on paper, it is challenging to keep it, and when we look for information, it takes a long time.
2. Data protection
In computers, we can store confidential data, such as customer information, financial data securely. Also, data can be protected against loss. However, if the data is stored manually, there is a risk of data loss and data privacy is questionable.
But now there are so many options like cloud storage helps to make our data easier to available and secure.
3. Documentation and presentation
Computers are used to create official documents and presentations. While this can be done when creating PowerPoint online presentations, we can present them neatly and more clearly.
Calculations can also be made using spreadsheets because they have built-in mathematical functions. Now you can create multiple types of files on softwares like Microsoft Office. Now, on Microsoft 365, you can easily work on your files from multiple devices.
4. Internet and browsing
Computers are useful for finding information on the internet. In today’s world, we can see every information about everything online. We can also contact an online service provider, and many companies are doing online.
After COVID-19, most of the students have taken their education online. Also, internet became one of the most powerful helping sources for education in lockdown situations.
Many tasks difficult for people can be done using computers and robotics in many areas, such as industry, space exploration. Robotics has become a technology boom.
Various types of experiments and space research computer helps a lot. Without computer communicating with space astronaut and calculating various measures is impossible.
6. Cost Efficiency
Because data is kept online, the need for hard copy storage is reduced drastically, that reduces costs and increases productivity.
You do not need to do any extra paperwork and materials to you keep your documents. So, you do not have to invest any extra money.
7. Quick Work
Today computers are being used on a large scale universal, the large-scale cause for this is that it works much quicker than humans, it can do extensive calculations in a few seconds.
Nowadays, most of the developers develop computer apps and software programming withing few minutes using computers. Computers are now so faster and reliable.
Some laptop companies are now providing 32Gb Ram and High-power processors, which will solve your millions of calculations in few seconds. Also, you can create high-definition design quickly using various software’s.
8. Easy communication and contact
Computer can be used to contact your friends anytime and anywhere through features like video calls, email, social networking.
Now the technology facilitates banking works like transfer money, documents to anyone sitting anywhere at home. So, this is one of the best and easiest communication devices in today’s generation.
Disadvantages of Computers
Although in today’s world, we encounter many difficulties while using a computer, there are also a few disadvantages but less than advantages to this upcoming technology.
Some disadvantages of computers are:
1. Virus and data loss
Computers are preferred for storing and protecting data. However, when a virus attacks a computer, maybe valuable data will be lost and may not recover it.
So, you must have to buy a yearly or three-year anti-virus protection service to keep your computer safe from virus and ransomware attacks.
2. Making people lazy
While the computer is making people smart, another one is using more is making people ill as more use of computer and mobile phone is proving to be harmful to health. Long working on the computer harms to eyes because of continuous viewing on the screen.
Presently the people are more involved with the computer and internet despite physical meeting, talking among society.
3. Cause of unemployment
In large companies and factories, many works are working by computers and robots, that has also increased unemployment.
It is an enormous risk for employees in the next generation when everything will computerize and done by robots.
4. Hacking of data and credentials
If you do not use internet banking carefully, there is a risk of your data stolen, which causes many users to suffer financial loss. Similarly, on the social networking site, if not working carefully.
Cheating through the internet has increased in a big way. You must aware of all fraud calls and emails to avoid this type of hacks. Also you have to use it good antivirus protection in your computer.
In this article you have read advantages and disadvantaged of computers. If we use this computer technique in the right way, our future can change a lot.
But its wrong use can also spoil our life. Use it correctly, safely, and enjoy the modern era of technology and science. Hope you liked this informative post on pros and cons of computers.
