2. What are softwares ?
 SOFTWARE“A set of instructions given to the
computer to solve a problem is called Software.”
 “Software is a single/collection of programs that
performs a particular task.”
 Software is also called Program.
 Different software's are used to solve different
problems.

3. Why do we use software?
 Computer needs the software to work.Softwares include
operating sysytem , sysem software and application software.
Without OS we cannot operate the computer. So we need
softwares to run the computer. Software may also be written
in an assembly language, essentially, a
mnemonic representation of a machine language using a
natural language alphabet. Assembly language must be
assembled into object code via an assembler.
Various kinds of
Softwares

4. Types of softwares :
 Software are divided into two types
depending upon their functions and utiity.
They are :
1. System Software
2. Application Software

5. System softwares
• System Software is set of programs to
control and manage the operations of a
computer hardware.
• It enables application programs to execute
properly.
• It consists of the basic operations as follows:
▫ Saving data on disk
▫ Making computer to work for us
▫ Printing a document etc.

6. EXAMPLES
• Examples of System Software's are:
▫ Operating Systems
▫ Utility Programs
▫ Device Drivers

7. Types of system software
 The different types of system softwares are :
1. BIOS
2. Operating System
3. Device Drivers
4. Language Processors

8.  Bios: The Basic Input/Output System (BIOS), also known as System
BIOS, ROM BIOS or PC BIOS is a de facto standard defining a
firmware interface. The fundamental purposes of the BIOS are to
initialize and test the system hardware components, and to load
a boot loader or an operating system from a mass memory
device.

 Operating Sytem: An operating system (OS) is a collection of
software that manages computer hardware resources and
provides common services for computer programs. The
operating system is an essential component of the system
software in a computer system. Application programs usually
require an operating system to function.

9.  Device Drivers : In computing, a device driver is a computer
program that operates or controls a particular type of device
that is attached to a computer. A driver typically
communicates with the device through the computer bus or
communications subsystem to which the hardware connects.
 Language Processor

 Language processor : A program that processes programs
written in a programming language is called language
processor. Part of a language processor is a language
translator, which translates the program from the source
language into machine code, assembly language, or some
other language. The machine code can be for an actual

10. Operating System in Detail
An operating system (OS) is a collection of software that
manages computer hardware resources and provides
common services for computer programs. The operating
system is an essential component of the system software in a
computer system. There are three types of operating system :
1. Single user operating system
2. Multi user operating system
3. Real time operating System

11.  Functions of operating system are :
1. It communicates with hardware and peripheral
devices
2. It provides user interface
3. Manages different types of memories
4. Provides a structure for accessing an application
5. Enables user to manipulate programs and data .

12. Application Software
• Application Software includes programs that do
real work for user.
• Application Software is created to perform
specific tasks for a user.
• It is also known as application package.
• Application software is used to perform various
applications on the computer

13. Types of application
software :
 The application softwares can be divided into
different categories depending upon their uses ,
they are :
1. Utility software
2. General purpose application software
3. Specific Purpose Application software
4. Developer Tools

14.  Utility Software : Utility software is application
sofware designed to help analyze, configure, optimize or
maintain a computer. Utility software usually focuses
on how the computer infrastructure (including the computer
hardware, operating system, application
software and data storage) operates.
Utility Softwares
 General Purpose (AS): General purpose application software
refers to software that can perform many different related tasks.
Word processors, spreadsheets and databases are all examples of
application software. Others include graphics and presentation
software

15.  Specific Purpose :Specific Purpose application software
is very specific in its use. Engineering programs often fall
under this category - there is a program that does slope
stability analysis and nothing else, for instance. Specific
purpose software may also be created in house and
tailored to the specific needs of the company.
 Developer Tool : A programming tool or software
development tool is a program or application that software
developers use to create, debug, maintain, or otherwise support
other programs and applications. The term usually refers to
relatively simple programs, that can be combined together to
accomplish a task, much as one might use multiple hand tools to
fix a physical object.

16. Utility Software / program:
• Utility program is a system software that
allows a user to analyze, configure and
Maintain the computer.
• It performs a specific task related to the
management of computer.

17.  The different types of utility software are :
1. Back up utility software: Backup software are computer
programs used to perform backup; they create supplementary exact
copies of files, databases or entire computers. These programs may
later use the supplementary copies to restore the original contents in
the event of data loss.
2. Compression software: A disk compression software
utility increases the amount of information that can be stored on
a hard disk drive of given size. Unlike a file compression utility which
compresses only specified files - and which requires the user designate
the files to be compressed - a disk compression utility works
automatically and the user doesn't need to be aware of its existence.

18. 3. Antivirus Program : Antivirus or anti-virus
software is software used to prevent, detect and remove malware ,such
as: computer viruses,
alicious BHOs, hijackers, ransomware, keyloggers, trojan
horses, worms,malicious LSPs, dialers, fraudtools, adware and spyware. Co
mputer security, including protection from social engineering techniques,
is commonly offered in products and services of antivirus software
companies.
4. Disk Cleaner : Disk cleaners are computer programs that find
and delete potentially unnecessary or potentially unwanted files
from a computer. The purpose of such deletion may be to free up
disk space, to eliminate clutter or to protect privacy.
