Essay on Computer

Introduction:

Computer is one of the most important inventions of this century. Today, the computer has started doing all the tasks of accounting and thinking which only the human brain used to do. For this reason, the computer has been called the 'machine brain'. Its development work has been going on for a long time and even today scientists are trying to take work from it which is outside the capacity of human beings.

History of computer:

Since the beginning of civilization, human has been struggling to overcome the problem of calculation. Initially 400 B.C. In C, humans used their fingers for calculation. Traders in Japan and China used Abacus for calculations. In 1645 AD, Mr. Napial discovered a calculating device known as a mechanical calculator. In 1840, Charles Babbage built the analytical engine for calculation at the request of the Royal Society. Charles Babbage is considered the father of modern computers and Lady Ada is considered the father of computer. Mr. Herman Hollerith built a machine also known as a punch card machine or punch card reader or Hollerith card. In 1900 A.D. Hollerth commercialized his work and established the Tabulating Machine Company (TMC). In 1924 A.D. Watson became the president of this company and gave a new name to this company which is known as International Business Machine (IBM).

Computer technology has advanced a lot in the last four decades. In 1944, Professor Ekins and his team invented the first computer known as Mark-1 at Harvard University, USA. Today the world stands at the entrance of the computer revolution and computers will play a very important role in the coming decades. Today there is no place where computer is not helpful.

Advantages of Computer:

1) The speed of computer work is much faster than humans. It finishes its work in the blink of an eye. The speed and ability to process data cannot be countered by humans. The working speed of a computer is measured in microseconds, nanoseconds and picoseconds. Now you can guess yourself how fast the computer works and processing data?

2) A human cannot remember a thing for years. But a computer can, because its storage capacity is very high. And it can preserve data in the same state for many years. Also, it is possible to use memory on another computer as well.

3) The computer is a very hard working and fatigue-free device. It can work continuously without getting tired for hours, days. Like humans, the computer does not have problems like tiredness, boredom, meditation. Since it is a machine, a person knows about its lifetime. That generates trust. This is the reason today humans have started to trust this machine more than themselves.

4) It performs its own work after giving necessary instructions to the computer. Then it does not need a human being. In the automobile sector, robots have handled all the work. They are also being used well in packaging and warehouses. Automatically its dependence is not on humans.

5) We can communicate with each other like humans, computers. And available information can also exchange data. Modern technology has made us humans able to communicate with computers. Now we can easily share our talk with the computer through voice commands. The computer uses various tools and techniques for this task. Which includes computation devices, LAN, WAN, modem, Wi-Fi, Bluetooth, etc.

6) A computer is a versatile device. That is, it can do many types of work alone. And all the different tasks can be completed without equal speed, accuracy and boredom. For example, you can paint while listening to songs. You can reply to chatting while reading a document. If you want to work on two software simultaneously, then its convenience is also easily found. Its specialty here makes it different from other devices.

Disadvantages of Computer:

Just like a coin has two sides. In the same way, there are not only benefits of computer, but there are also some disadvantages of computer. Which are discussed below.

1) You have read above that, a computer is an automatic machine. So what is the need of humans for this? The matter is true, but this fact also cannot be denied. The bin human-computer is just a box with various devices. Automation is one of its features. However, it is effective only if the person has given it some instructions. If instructions are not given, then the computer will not be able to do anything on its own. Therefore, it always depends on human beings to take instructions.

2) A computer has no intelligence of its own. So it is not possible to think. It can only process data based on the instructions and functions already provided. Robots and other automated machines are an example of this. You give them instructions. And they will continue to do the same thing. Whether there is any obstacle ahead of them. It makes one feel like leaving the key in the toy. However, computers are some advanced toys. Those who have the ability to inform if there is a deficiency. Neither computer has the ability to understand and express happiness and sorrow. Because, computers are emotionless.

3) A computer needs a clean and dust-free environment to function. Only then it continues its work smoothly. If it will be installed to work in a place filled with dust and dirt. Its working capacity will be badly affected and it will be unable to work for a long time.

4) Computer has created its own world. Which is known as the cyber world. Various dangers have taken birth in this unknown world. From which only the computer can do its work according to our wish. If it is hacked, then it will not do its job on instructions to the computer. But what the hacker says will only work.

Conclusion:

In modern era, computers and robots will definitely prove to be revolutionary. They are adding a new chapter in human history. Robot is able to do all kinds of work and the computer is ready to help him. Both computer and robot sensing are zero, the brain is zero, they are just instruments. Therefore, it is necessary to control them with sensations. Their misuse can also be as destructive as beneficial.
