The document discusses different types of software, including system software, application software, utility software, and operating systems. System software provides a platform for other software to run and controls hardware resource allocation. Application software allows users to perform specific tasks. Utility software includes programs that optimize computer performance like virus checkers. Operating systems enable computers to function and communicate by providing an environment for applications and an interface between users and computers.

1. ❖ Topic:
Software.
❖ Sub-Topic:
● Application and System Software.
● Operating System.

2. ❖ Software:
● Software is a set of instructions, data or programs used to operate computers and execute specific tasks. It is the
opposite of hardware, which describes the physical aspects of a computer. Software can be divided into different
types, such as system software, and application software.
❖ System Software:
● Set of programs to control and manage the operation of comp H/ware.
● Provides a platform on which other software can run.
● Required to allow H/Ware and S/Ware to run without problems.
● Provides a human computer interface (HCI)
● Controls the allocation and usage of hardware resources.
● Some examples of S/Ware are O/S system , Utility programs , and Device Drivers.

3. ❖ Application Software:
● Used to perform various applications on a comp.
● Allows a user to perform specific task using the computer resources.
● May be a single program or a suite of program.
● User can execute the software as and when they require.
● Some examples of application software are spreadsheet, word processor, and
database.
For e.g. —>

4. ❖ Utility Software:
● Computer Users are provided by number of Utility programs that are part of
system software.
● Utility Software are often initiative by the user, but some, notably virus
checkers often just run in the background without the need of any user input.
● Some Utility programs are Virus Checkers, Backup Softwares, Security, and
Screensavers.

5. ❖ Operating Systems:
● To enable computer systems to function correctly and to communicate with
computer systems, software known as an operating system needs to be
installed.
● An operating system provides both the environment in which applications can
be run and a useable interface between human and computer.
