Computer is a complex device which is used for storing and sifting data. It includes a wide variety of functions and can be used in many sectors of life. Computer knowledge gives a detailed idea about the functioning of computer, its maintenance, hardware and software.
Computers are an integral part of our daily lives. They have been responsible for so many inventions, development and changes in our lives. There are different types of computers available like Desktop PCs, Laptops and Desktops, Portable Computers and even smartphones. And each type has various kinds of names and functions
Computer knowledge has evolved over the years and with it, the various questions on computer knowledge have remained relatively unanswered. For example, one might be wondering, how exactly does a computer know what to do based on the data inputted?
The question is as old as computers themselves. However, over time computers have evolved and improved their capabilities to store and process data at staggering speeds. This means that in order to be able to explain how they work you need to go back a generation and ask questions not yet resolved by today’s technology. This article aims at providing answers to some of these fundamental questions regarding computers.
