Computer is a great invention of modern technology. It is a normal machine which has the ability to store a lot of data in its memory. It works using input (like keyboard) and output (printer). It is very easy to use, so even young children can use it very easily. It is very reliable which we can keep with us and use anywhere and anytime. With this, we can create new data along with changes in our old data.
Preface
The invention of computer has made many dreams come true even we cannot imagine our life without computer.
Generally, it is a device that is used for many purposes such as keeping information secure, e-mail, messaging, software programming, calculations, data processing etc. CPU, UPS, keyboard, and mouse are required to work on a desktop computer, whereas all these are already present in the laptop.
Computer is an electronic device with large memory which can keep any data safe. In the 21st century, we are living in a kind of modern world of computers.
Charles Babbage built the first mechanical computer
Earlier generations of computers were of very limited working capacity whereas modern day computers can perform a lot of tasks. Charles Babbage built the first mechanical computer, which was very different from today's computers. The goal of the invention of the computer was to create a machine that could perform mathematical calculations very rapidly.
During the Second World War, there was a need for machines that could predict the speed and direction of enemy weapons and find their exact position, which became an important reason for the creation of computers. Today's computers are equipped with artificial intelligence technology which helps us in every walk of life.
New Generation Computers
The new generation computers are highly advanced i.e. they are small, light, and fast as well as very powerful in terms of functionality. In today's time, it is being used in almost every business like- examination, weather forecasting, education, shopping, traffic control, high level programming, railway ticket booking, medical field, business etc.
With the Internet this is the mainstay of information technology and it has proved that nothing is impossible in today's time. There are hundreds of advantages of computers for human beings, then there are also disadvantages like cyber crime, pornographic websites, which are easily accessible to our children and students. By some measures we can avoid its negative effects.
Importance Of Computer
- Today computer has made our life and work very easy. In fact, the computer is a great invention of modern technology.
- Today we can easily do all the work through computer in all the banks.

Conclusion
In today's time, the dependence of the human species on computer technology is increasing very rapidly. In today's time, no person can imagine his life without computer, because it has spread its feet everywhere and people have become accustomed to it.
Computer has also become an important part of every student's life. They can use it for making projects, for learning poetry, for stories, for downloading exam notes, for gathering information, etc in a very short amount of time. Along with increasing the skill development of the students, it is also very helpful in helping them to get jobs.
