What is a computer?
Computer is an advanced electronic device that takes raw data as an input from the user and
processes it under the control of a set of instructions (called program), produces a result
(output), and saves it for future use. This tutorial explains the foundational concepts of
computer hardware, software, operating systems, peripherals, etc. along with how to get the
most value and impact from computer technology.
There are three basic functionalities of a Computer System and they are
1. Input 2. Process 3. Output
But if we look at it in a very broad sense, 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.
