The document summarizes software and its classification. It defines software as a set of instructions that control computer operations. Software is classified into system software and application software. System software includes operating systems, language processors, and utilities. Application software is developed for specific tasks like word processing, spreadsheets, databases. The document also discusses the relationship between hardware and software, and provides examples of software figures.

5. INTRODUCTION
Software is a set of instructions to perform a desired and useful
work, by which the operations of the computer for the computations
and processing are controlled.
The term software system can be defined as the system software
and application software that must be added to a host machine
(hardware) in order to realise some desired function.
The computer consists of hardware and software and the software
drives the hardware. That means without the software the computer
can do nothing.
The process of software development is called programming.
To do programming the programmer should have detailed
knowledge of the problem to be solved, the corresponding algorithm
and the particular programming language to solve a problem or
develop software.

6. SOFTWARE
A sequence of instructions written in a language that can be
understood by a computer is called a computer program, the
program is called SOFTWARE.
A computer without software is like a body without life.
A computer is an extremely fast, accurately calculating machine
that takes data as input and processes them according to a set of
instructions to produce the desired result as output.
When a stored software program is executed, the following things
happen:
1) Data get into the computer’s memory from an input device like
keyboard or secondary storage device such as floppy diskette or hard
disk.
2)The data given as input is processed according to the program.
3)Output information is produced on the VDU (i.e. softcopy) or
printed on to a sheet of paper (i.e. hard copy)

7. Classification of Software
 System software
 Application software
• System software
 System software , also known as a system package, is a set of one
or more programs designed to control the operation of a computer
system.
 System software is a collection of programs that directly control
the computer’s internal operations and also that help ordinary
users to make use of a computer effectively and efficiently.
 The programs included in a system software are called system
programs and the person who prepares systems software is
referred to as a system programmer.

8. Classification of System Software
•Operating system
Operating system, which acts as an interface between the user and
the hardware, is a set of programs that control, and co-ordinate the
operations of a computer and help to make efficient use of its
resources.
•Main Functions Of Operating System
Process Management
Memory Management
File Management
Security
Command Interpretation

9. •Language processors
A computer can understand only machine language.
Languages processors are the system program that translates
assembly or high level language instructions into equivalent machine
language instructions.
Different type of language Processor
Assemble
The assembler of a computer system is a system software, supplied
by the computer manufacturer, which translates an assembly
language program into its equivalent machine language program.
Compiler
Compiler is a translator program, which translates a high level
language program into its equivalent machine language program.
Interpreter
It takes one statement of a high level language program, translates it
into machine language instructions, and then immediately executes
the resulting machine language instructions.

10. •Application software
•Software developed for specific application is called application
software.
Application software is a set of one or more programs, designed to
solve a specific problem, or do a specific task for an individual or an
organization.
Application software includes prewritten software packages, custom
made programs and utilities.
Prewritten software
Prewritten software packages address the processing needs of many
users, whereas custom-made programs (customized software) meet
the requirements of specific organization or individual. Prewritten
software are:
1)Word processing packages 2)Graphics and multimedia packages
3)Electronic spreadsheets 4) Database management packages
5)Desk top publishing packages

11. Utilities
Utilities are those application programs that assist the computer by
performing housekeeping functions like backing up disk or
scanning/cleaning viruses or arranging information etc. some
important utilities are:
1)Test Editor 2)Bank up Utility 3)Compression Utility
4)Disk Defragmenter 5) Antivirus Software
Customized Software
Custom-software development is needed as a consequence of
computerization process. Custom-made software are generally for
data-processing needs and building information system. Some
common application where custom-made software is required are:
1) Payroll 2) Accounting
3) Air-line reservation 4) Insurance
5) Government 6) Banking
7) Library management 8) Sales and Inventory Control
9) Hospital management

12. Relationship Between Hardware & Software
 Both hardware & software are necessary for a computer
to computer to do useful job. Both are complementary to
each other.
 Same hardware can be loaded with different software to
make a computer perform different types of jobs just as
different songs can be played using the same cassette
player.

14. Classification of Software

15. CONCLUSION
Software is a set of instructions to perform a desired and
useful work, by which the operations of the computer for
the computations and processing are controlled.
The term software system can be defined as the system
software and application software that must be added to a
host machine (hardware) in order to realize some desired
function.
The term software refers to a collection of programs.
