What is a Computers?
Why do we need computers?
We built computers to expand our brains. Modern times meant complex prolems with complex solutions. We needed help.
Computers are our best buds.
Computers gave us a way to store, retrieve and process data.
Computers process data and carry out complex calculations within a few seconds.
They can also be connected to a network making it possible to share information over large distances.
The points / note : Computers are indispensable to us today.
How do computers work?
Computers is an Electronic device that can receive information, perform actions on the basis of rules and provide an output.
Using these functions a computer can access, store, process, and relay information to its use within seconds!
The points / note : You can think of computer as :
--INPUT--->OUTPUT--->PROCESS
it accept data, make changed to it, based on certain conditions and displays the result.
My Computer Understands Me
Computers understand everything in combinations of 0 second and 1 second, but also know how to build complex things out of . This is called Binary Code.
For example :
==================================
| Text |==========| Binary Equivalent|
| a |===========|01100001 |
| A |===========|01000001 |
