What is Hardware and Software

Hardware deals with the physically existing parts of a computer which we can touch and feel. Whereas software is the set of instructions given to a computer which we can see and feel.

Software is divided into 4 parts namely:

  1. Operating System
  2. Language
  3. Package
  4. Application

Operating System is an interface between the user and the computer.

Language is the collection of pre-defined words. Computer languages are of 3 types:

  1. Low level languages which consists of only 0’s and 1’s
  2. Middle or Assembly level languages which is a combination of low and high level languages.
  3. High level languages which consists of purely English like words.

Package is developed from a language. It is used for some generalized particular purpose.

Application is developed from a package. It is for being applied. No further software can be developed from it.
