                 Computers have become integral to our daily lives in the modern era. We use them for studying,
                 banking, shopping, traveling, e-commerce, entertainment, and many other activities. Knowing
                 the basics of computers is now a common skill for everyone. However, learning more about how
                 computers work can be very helpful, especially since the future will rely heavily on technology.

                 Let us explore computers in detail and learn how they function. By understanding the different
                 parts of a computer, we can gain a clearer idea of how they work and use this technology more
                 effectively for our needs.

                    WHAT IS A COMPUTER?

                 The word "Computer" originates from "compute," meaning "to calculate."
                 A computer is an electronic device designed to store, process, and display
                 information. It is commonly used for tasks such as solving mathematical
                 problems, creating documents, playing music, and accessing the Internet.
                 Characteristics of a Computer

                 Some important characteristics of a computer are as follows:

                    Speed:  Computers  can  process information  and  perform  calculations  at  incredibly  high
                    speeds, much faster than humans.
                    Accuracy: Computers follow instructions exactly, making them highly accurate with minimal
                    errors if the instructions are correct.
                    Storage: Computers can store vast amounts of data and retrieve it whenever needed, allowing
                    for easy access to information.
