Hello Everyone, My name is AbdulAziz I'm a new member here and i can give lectures on many different topics but I'm going to start my discussion with Computer. Because i have better knowledge on Computer and Computer applications etc. 

So, what is Computer?

A Computer is a programmable device that can store, retrieve, and process data.

Here is a short definition of Computer. but this is my first post and that's why I'm going to end it with just a little definition.
