2.  Computer software, or just software, is any set of machine-
readable instructions that directs a computer's processor to perform
specific operations. Software is a general term. It can refer to all
computer instructions in general, or to any specific set of computer
instructions. It is inclusive of both machine instructions and source
code

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

5.  System software is computer software designed to operate
the computer hardware, to provide basic functionality, and
to provide a platform for running application
software. System software includes device drivers, operating
systems, servers, utilities, and window systems. The different
functions of system software are :
1. Reading data and recieving information.
2. Translating data and instructons .
3. Controlling all the peripheral devices.
4. Processing and generating output.

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

7.  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.

Operating System

8.  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 : 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 computer or for a virtual
computer.

9. 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

10.  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 .

11.  Application software is all the computer software that causes
a computer to perform useful tasks (compare with computer
viruses) beyond the running of the computer itself. A specific
instance of such software is called a software
application, application or app. Examples
include accounting software, enterprise software, graphics
software, media players, and office suites. Many application
programs deal principally with documents.

12.  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

13.  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

14.  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.

15.  Utility software is system software designed to help
analyze, configure, optimize or maintain a computer. Utility
software usually focuses on how the computer infrastructure
operates. Due to this focus, utilities are often rather technical
and targeted at people with an advanced level of computer
knowledge - in contrast to application software, which allows
users to do things like creating text documents, playing video
games, listening to music or viewing websites.

16.  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.

17. 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.
