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
