Good day, hope all are well. Today I will explain to all about computer basic thing. These topics will help you to make a expert computer operator and very knowledgeable person about computer.
I thought there many new users who just brought their computer/laptop and joined internet just now they don’t know many thing what a professional computer users know. So I am trying to know that kinds of new users who just came IT world and welcome to them here.
Computer is an electronics device which specially works with information. Computer doesn’t know without 1/0. All information converts into Zero/One then execute.
We can answer that – A Computer is one kinds of multitasking electronics machine which can memorize data/information into its Memory/Disk after accept/receive data, permutation data and resolution that data. We get a 100% accurate result after computer program execute. Computer cannot do anything without program. So we can tell it Calculate or programmable electronics machine.
Other side we can tell as shortly – Computer is a system program solving electronics machine whose use for data processing or information processing.
My Quote that “Human can do wrong in his calculation but Computer cannot do anything wrong if program play accurately”.
“Charles Babbage” who 1st design a mechanical computer and for that reason I called him Grand Father of Computer. He made a Analytical Computer where he used ROM (Read Only Memory) in the form of punch cards.
