Software:

Digitalised automated process is called software.

• Whenever graphic user interface is available then it is called digitalised, without human interaction, if the process is completed, then it is called automated process.
• A software is a collection of programmes.
• A program is a set of instructions which is designed for particular task.
• ‘N’ no of programs combined together like a single unit, it is called software tool or software component.
• Software’s are classified in to two types:

  1. System software
  2. Application software.

 1. System software: This software is designed for general purpose and doesn't having any limitations.

Then it is called system software.

E.g. Operating system, compiler.

 2.Application Software: This software is designed for particular task and contains limitations. It is called Application software.

E.g.: MS.Office, oracle, Tally.

• By using MS.Office, we can maintain information in document format.
• By using oracle, we can maintain information in Table format.
• By using Tally, we can maintain account related information.
• A computer is an Electronic device which accepts the instruction from the user, according to user send
• Instructions, it produce results.
• Who, using the applications is called user and who developing the application is called programmer.
• The basic purpose of Language is communication.
• Computer knows only one language i.e., Binary format.
• As a programmer, when we required to interact with a computer, we need a communication channel, it is called programming language.
• A programming Language is a special kind of instructions which is used to communicate with computer.
• As a programmer, if we knows the programming language, we can’t interact directly with computer because computer cannot understand programming language code. (It knows only binary language)
• In above case, we required a Mediator, called “Translator”

                As a programmer, we required to give the instructions in programming language, translator will converts programming language into binary format, then according to the given instruction we will get an application / Result.

Programmer   p.l      Translator   Binary    Computer    App/result

                                                Complier

                                                Interpreter

                                                Assembler
