Data & Information In Computer

In Computer, Data is a collection of raw things or we say unprocessed things which includes texts,Images,numbers,audio and video.Data is any thing this is not being using by user.Data is stored in Computer Storage device.We stored data on hard disk because it is our need in future.We do not take decision using data.

Information is also data but not raw data it is data that is processed data or we say convey meaning to the data.We use knowledge to process data.The information is always useful for the user of the Computer.Our process data is Called Information.The people take decision on the basis of information.

Data and Information are the basic Terminology of Computer System.

Computer Categories

We define Computer into the following Categories:

  • Personal Computers (Desktop Computers)
  • Super Computers
  • Mobile Computers
  • Servers
  • Mainframes
  • Embedded Computers

Personal Computer are usually use at home/offices  etc. it is placed on a desk.

Super Computer are very Expensive one's and very fast.It is make for some special purpose.

Mobile Computer are know as Mobile Phones.

Server are Computers that stored a lot of data on Storage Devices.Any Computer on network in which we install active directory is  called Server.

Mainframes are also like super Computers but less fast and expensive.

Embedded Computer functions as a component in any product. e.g microwave oven.

Knowledge of Computer and Information Technology For Beginers

Computer
                Computer is a Binary Machine which take input from users process them and display an output.We Can also say Computer Can store date,calculate data,retrieve data and also print data.
                 Computer is a Machine which knows only 0 and 1.

The First Computer Maker
                                                      Charles Babbage
The First Computer Programmer
                            Ada Lovelace
                  To study Computer After Intermediate, Universities Offers these Courses.

  • Computer Science
  • Information Technology
  • Software Engineering
  • Computer Engineering

We will discuss only Information Technology in this Blog:-
Information Technology
                  Information Technology is a part of Technology in which we develop Things using Computers.
OR we say any thing that is developed by using computer is Information Technology.Information Technology offers Subjects like Programming, Database, Web Development, Networking. Most of the times Computer Science and Information Technology are assumes as same subjects but actually they are not same.Information Technology is about making application of the Computers.
