Software is a collection of programs and instructions that allow computers to perform tasks. There are two main types of software: system software and application software. System software includes operating systems, language processors, and utility programs. It manages computer hardware and allows other software to function. Application software is designed for specific tasks used by end users, like office suites and photo editors.

2. 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.

3. 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.

4. Types of software
Software

5. 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

6. 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

7. 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.

8. 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

9. 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.

10. 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.
