This document discusses different types of computer software. It defines hardware, system software, application software, and utility software. System software includes operating systems and language translators like assemblers, compilers, and interpreters. Application software is divided into general purpose software for tasks like word processing, spreadsheets, etc. and specific purpose software for accounting, reservations, and more. Utility software helps manage computer systems with tools like disk cleanup, backup, file compression, and antivirus protection.

3. Those parts of computer system which can be
touched or felt are called hardware.
Such as..
WHAT IS HARDWARE..?

5. The set of all programs, documentations and procedures which take care of
proper functioning of a computer system are called software.
There are three types of software:-
a) System software
b) Application software
c) Utilities
WHAT IS SOFTWARE..?

6. The software which monitors the basic activities of a
system is called system software.
The system software contains those program that
control and support the computer system and its data
processing applications.
It includes:
Operating System
Language Translator
SYSTEM SOFTWARE

7. Operating System
The low-level software that supports a computer's basic
functions, such as scheduling tasks and controlling
peripherals.
Language Translator
Translator is a computer program that performs
the translation of a program written in a given
programming language into a functionally equivalent
program in a different computer language, without losing
the functional or logical structure of the original code (the
"essence" of each program).

8. ASSEMBLER:
It is used to convert a program written in assembly language into machine language.
COMPILER:
Translates a source program that is usually written in high level language in machine
language.
For each high level language, the computer requires separate compiler. A compiler
creates a unique object program.
INTERPRETER:
Translates each source program statement into a sequence of machine instructions
before translating the next statement.

TRANSLATORS

9. Scans the entire program first
and translates it into machine
code.
When all the errors are
removed, execution takes place.
Slow debugging
Execution time is less
Translates the program line by
line.
Each time the program is
executed the error checking
takes place.
Fast debugging.
Execution time is more.
Compiler Interpreter
SOME DIFFERENCES BETWEEN…

10. Application software is the set of programs designed for specific uses or
perform the task of his choice.
It is of two types:
General purpose application software
Specific purpose application software
APPLICATION SOFTWARE

11. General purpose application software would be anything that aids in allowing
you to accomplish simple computer related tasks.
For example:
word processing software
presentation software
Database management
GENERAL PURPOSE
APPLICATION SOFTWARE

12. Word Processor Spreadsheet
0 A word processor is an
electronic device or
computer software
application, that performs
the task of composition,
editing, formatting, printing
of documents.
0 Some word processing
software are:
0 Microsoft word
0 Corel WordPerfect
0 An electronic document in
which data is arranged in the
rows and columns of a grid
and can be manipulated and
used in calculations.
0 Some of the software for
making a spreadsheet are
0 Microsoft excel
0 VisiCalc
0 supernal

13. Presentation Database Management
0 A presentation program is
a software package used to
display information in the
form of a slide show.
0 Some software to make a
presentation are
0 Microsoft PowerPoint
0 Open Office Impress
0 A database
management system
(DBMS) is a computer
software application that
interacts with the user, other
applications, and the
database itself to capture
and analyze data.
0 For example
0 MySQL
0 SQL servers

14. Graphics Packages Desktop Publishing
0 In computer
graphics, graphics
software refers to
a program or collection of
programs that enable a
person to manipulate images
or models visually on a
computer.
0 For Example
0 Adobe Photoshop
0 Coral draw
0 The production of printed
matter by means of a printer
linked to a desktop
computer, with special
software.
0 For example
0 Adobe PageMaker
0 Coral draw

15. These software generally has one purpose and
solves a specific task.
For example
SPECIFIC PURPOSE APPLICATION
SOFTWARE

16. i. Accounting Management: it is an application that brakes and
creates accounting transactions into stages of steps that works
within the main system.
ii. Reservation System: with a reservation software, you can have
more control of the reservation system for your tickets and avoid
double bookings.
iii. H R Management: with H R Management software you can
reduce the amount of time that your human resources
department spends managing employee information and other
tasks.
iv. Windows movie maker : It does one and only one task, which
would be making a movie.
v. Minesweeper and other games which are all made for one
purpose.

17. vi. Attendance system: It is based around tracking student/employee
absentees, since there should be fewer of them than presences.
vii. Payroll System: The term Payroll encompasses every employee of
a company who receives a regular wage or other compensation.
viii. Inventory Management Software: This type of software helps an
organization in tracking its goods and materials on the basis of
quality as well as quantity.
ix. School Inventory Control System: It is a set of hardware and
software based tools that automate the process of tracking
inventory.
x. Billing System: It is a combination of a software application and
database designed to take customer information regarding charges
to be made to that customer.

18. These are part of the system software of a computer.
It is used for the management of computer hardware and application software
installed on a computer.
It carries some of the common tasks needed when using a computer.
For example:
UTILITY SOFTWARE

19. Disk fragmentation: Disk Defragmenter is used to rearrange files and
unused space on our hard disk so that programs run faster.
Disk Cleanup : We can run Disk Cleanup to help us free up space on our
hard drive . It searches our files and then lists temporary files ,Internet
cache files and unnecessary program files that you can safely delete.
Backup and Restore : Backing up our files is one of the most important
things we can do to safeguard the data we create and store on our computer.
File Compression: It is a software program that is used to reduce the file
size of one or more files.
Virus scanner/cleaner: these software are utility programs designed to
protect our computer from computer viruses. It is known as antivirus
software.
