Software

  1. 1. Software is a collection of program as well as set of instruction which are design and developed by software engineer to perform specific task and general task. Software is a most important component of computer system because it is responsible for perform a task given by the user. And it is also responsible for maintaining, updating ,and controlling the all software and hardware which are internally and externally connected to the computer system. For example office package , Photoshop etc.
  2. 2. Software Software is programs or instructions that tell the computer what to do and how to do it. Computers need software to do even a simple job, without software computers cannot function even with out program a user cannot boot computer system.
  3. 3. Types of software Software System software Application software OS LP Utility program Packaged Tailored compiler interpreter Assembler
  4. 4. Types of software Software is divided in to two types they are  System software  Application software System software: system software is a collection of program as well as set of instruction and the purpose of these program is to use of computer more efficient and easier. The system software's are responsible for managing , controlling ,controlling and updating the all hardware and software which are in the computer system. it is divided in to three types they are : Operating system Language processor Utility program
  5. 5. Types of software  Operating System: Operating system is a kind of system software which is responsible for controlling updating all hardware and software's. It is interface between computer user and computer hardware. It is also known as master controller of the complete computer system. For example Unix, linux,Mac, Vista,etc.  Language processor: Language processor is system software or it is also known as translator which trans late high-level language in to machine code instruction which is known as object code. It is also divided in to three types they are.  Compiler  Interpreter  Assembler
  6. 6. Types of software HLL(source code)  Compiler : Compiler is a system software and it is translator which translate high level language in to machine code instruction because computer hardware’s are only able to understand machine code instruction which is known as object code. It execute complete source code once a time in to machine code instruction.  HLL  (source code) Compiler Machine code (object code)
  7. 7. Types of software  Interpreter: It is also a system software or translator which high level language in to machine code instruction because computer hardware’s are only able to understand machine code instruction but it execute step by step or line by line , it reads each and every instruction and then execute that source code in to machine code instruction. HLL Interpreter Machine ccode
  8. 8. Types of software  Assembler : Assembler is a kind of software which is used to translate low level language in to machine code instruction because computer hardware are only able to understand machine code instruction. LBL Machine codeAssembler
  9. 9. Utility Program  Utility programs are also known as house keeping programming. Which are developed and used by it programmer it self to increase there programming efficiency. Like copy, paste etc.  Virus : it is software application which destroy the computer and its related devices and other application.  Anti virus: it is also a software which is used to protect our computer from virus. Like panda AVG etc.
