The present world is a data rich world and it has turned into a need for everybody to be aware of PCs. A PC is an electronic information handling gadget, which acknowledges and stores information input, processes the information input, and produces the result in an expected organization.
The purpose of this tutorial is to introduce you to Computers and its fundamentals.
Functionalities of a Computer
If we go more deep into the details related to computers, any digital computer carries out the following five functions −
Step 1 − Takes data as input.
Step 2 − Stores the data/instructions in its memory and uses them as required.
Step 3 − Processes the data and converts it into useful information.
Step 4 − Generates the output.
Step 5 − Controls all the above four steps.

Advantages of Computers
Following are certain advantages of computers.
