What is a computer?

A computer is a machine that can process information very fast. Computers are everywhere. They can be used to get information, play games, watch movies, and do other things. Even though computers have been around for a long time, no one knows how it works inside. There are many different types of computers called systems or models or brands which do the same thing but in different forms.

What information can a computer process?

A computer can process information that is made up of 1s and 0s called Binary information. This information is sent to computers as electric signals, which makes it possible for them to work very fast. The amount of information a computer can handle at the same time is called information processing capacity. Humans can process 10 bits of information at once (which equals 0 – 9). Computers, on the other hand, can process information in chunks that can stretch up to 260 or even more. That’s the reason why computers are always used as pretty fast information processors. It makes it possible for them to handle information that’s needed to make the information work.

The computer is one of the most important information tools that are used in modern times. This information processing tool has become a pretty useful device because it makes it possible for the information to be processed quickly and correctly, without any errors. The basic information about computers would be information processors which are made up of information processing capacity, information processing speed, and information storage space.
