                 Computers are an essential part of our everyday existence in modern times. They are present in all
                 our daily tasks, whether it's studying, banking, shopping, transport, e-commerce, entertainment,
                 or any other activity we engage in. This has made computers a part and parcel of our lives, and
                 everyone knows its basics. It is an advantage to know more than just the basics of computers, as
                 the future we foresee will be driven by technology.
                 Let's take a closer look at computers and understand how they work. By learning about each part
                 of a computer, we can have a better understanding of it and will be able to use this technology
                 for our benefits.

                    WHAT IS A COMPUTER?


                 A  computer  is an  electronic  device  that  processes information  and
                 performs tasks based on instructions. It can receive input (like typing on
                 a keyboard), process it, and give output (like displaying on a screen). The
                 term "computer" does not refer to a single unit; rather, it is a combination
                 of two major components, hardware and software. We will learn about
                 hardware and software later in this unit.
                 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.
