2. A computer system can be divided into two components which are
responsible for providing the mechanisms to input and output data,
to manipulate and process data, and to electronically control the
various input, output, and their storage. They are known
as hardware and software.
Introduction
5. Computer Software:-
software, instructions that tell a computer what to do. Software comprises
the entire set of programs, procedures, and routines associated with the
operation of a computer system.
6. examples of system software :-
Windows XP, Windows Vista, Windows 7, Windows 8,
Windows 10, MAC OS, Linus, Unix.
Examples of Application Software
•Microsoft products such as Office, PowerPoint, Word,
Excel, Outlook, etc.
•Music Application Software's like Pandora and Spotify.
•Real-time online communication like Skype, Google
Meet, and Zoom.

7. Classification of computer
1. Based on size & Capacity
Micro
Mini
Mainframe
Super computer
2. Based on working principle
Analog
Digital
Hybrid
8. Based on size & capacity
Micro computer :-A
microcomputer is a complete
computer on a small scale,
designed for use by one person at
a time. An antiquated term, a
microcomputer is now primarily
called a personal computer (PC), or
a device based on a single-chip
microprocessor. Common
microcomputers include laptops and
desktops.
List of Microcomputer types
•Desktop Computer.
•Laptop.
•Smartphone.
•Notebook.
•Tablet.
9. Mini Computer :-
minicomputer, computer that was smaller,
less expensive, and less powerful than a
mainframe or supercomputer but more
expensive and more powerful than a
personal computer. Minicomputers were
used for scientific and engineering
computations, business transaction
processing, file handling, and database
management.
Mini computer examples: IBM's AS/400e,
Honeywell200, TI-990. Minicomputer can
support multi-users at a time or you can
say that minicomputer is a multiprocessing
system.
10. Mainframe computer :-A
mainframe computer, informally
called a mainframe or big iron, is a
computer used primarily by large
organizations for critical
applications like bulk data
processing for tasks such as
censuses, industry and consumer
statistics, enterprise resource
planning, and large-scale
transaction processing.
the first mainframe was
developed in the 1930's
by Howard Aiken, who was a
Harvard researcher.
11. Super Computer :-
Invented by Seymour Cray in 1951. A
supercomputer is a computer with a
high level of performance as compared
to a general-purpose computer. The
performance of a supercomputer is
commonly measured in floating-point
operations per second instead of million
instructions per second.
Uses & Purpose :-
Supercomputers are used for data-intensive and
computation-heavy scientific and engineering
purposes such as quantum mechanics, weather
forecasting, oil and gas exploration, molecular
modeling, physical simulations, aerodynamics,
nuclear fusion research and cryptanalysis.
PARAM Shivay was the first supercomputer
assembled indigenously, was installed in IIT
(BHU), followed by PARAM Shakti, PARAM
Brahma, PARAM Yukti, PARAM Sanganak at
IIT-Kharagpur IISER, Pune, JNCASR,
Bengaluru and IIT Kanpur respectively.
12. Based On Working Principle
1. Analogue Computer :-
An analog computer or analogue computer is a
type of computer that uses the continuous
variation aspect of physical phenomena such as
electrical, mechanical, or hydraulic quantities
(analog signals) to model the problem being
solved.
Examples of Analogue Computers:-
•Thermometer. An analogue thermometer makes use of a graduated scale and properties of mercury to fulfil its
operation. ...
•Speedometer. The speedometer is a device that detects the speed of a moving vehicle. ...
•Analogue Clock. ...
•Seismometer. ...
•Voltmeter. ...
•Flight Simulators. ...
•Tide Predictors.
13. Digital computer:-
digital computer, any of a class of devices capable
of solving problems by processing information
in discrete form. It operates on data, including
magnitudes, letters, and symbols, that are
expressed in binary code—i.e., using only the two
digits 0 and 1.
A typical digital computer system has four basic functional elements: -
(1) input-output equipment,
(2) main memory,
(3) control unit, and
(4) arithmetic-logic unit. Any of a number of devices is used to enter data and
program instructions into a computer and to gain access to the results of the
processing operation.
14. Hybrid Computer :-
Hybrid computers are mainly used for specialized
applications where both analog and digital data
processing is done. For Example, Hybrid
computers installed on a petrol pump do not only
measure the amount of petrol but also calculates its
value. In this way, It is capable of both functions.
Features:-
1.Hybrid computers have a high level of accuracy and are
capable of doing tasks quickly while maintaining high
accuracy.
2.They are widely employed in sectors such as defence,
forensics, and research due to their speed and accuracy.
3.They communicate with monitor and controller devices
directly.
4.It completes the task quickly.
5.They can effortlessly answer difficult equations.
6.They combine the features of both analog and digital
computers.
Examples :-
•Gasoline Station
•Electrocardiogram Machine
•Ultrasound Machine
•Monitoring Machine
•Research and Production Industries
•Forensic
•Defense
15. Software Components
Software is a set of programs, which is
designed to perform a well-defined
function. A program is a sequence of
instructions written to solve a particular
problem.
There are mainly two types of software −
System Software
Application Software
16. System Software: -
The system software is a collection of
programs designed to operate, control,
and extend the processing capabilities of
the computer itself. System software is
generally prepared by the computer
manufacturers. These software products
comprise of programs written in low-
level languages, which interact with the
hardware at a very basic level. System
software serves as the interface between
the hardware and the end users.
17.
18. Here is a list of some of the most prominent features of a system
software −
Close to the system
Fast in speed
Difficult to design
Difficult to understand
Less interactive
Smaller in size
Difficult to manipulate
Generally written in low-level language
19. Application software :-
An application program (application
or app for short) is a computer
program designed to carry out a
specific task other than one
relating to the operation of the
computer itself, typically to be
used by end-users.
Examples:-
Word processors
media players
accounting software
20. Features of application software are as
follows −
Close to the user
Easy to design
More interactive
Slow in speed
Generally written in high-level language
Easy to understand
Easy to manipulate and use
Bigger in size and requires large storage
space
21. Examples of Application software are the
following −
Payroll Software
Student Record Software
Inventory Management Software
Income Tax Software
Railways Reservation Software
Microsoft Office Suite Software
Microsoft Word
Microsoft Excel
Microsoft PowerPoint
22. Sr. No. Key System Software. Application Software.
1
Definition System Software is the type of software which is
the interface between application software and
system.
On other hand Application Software is the type of
software which runs as per user request. It runs on
the platform which is provide by system software.
2
Development
Language
In general System software are developed in low
level language which is more compatible with the
system hardware in order to interact with.
While in case of Application software high level
language is used for their development as they are
developed as some specific purpose software.
3
Usage System software is used for operating computer
hardware.
On other hand Application software is used by user
to perform specific task.
4
Installation System software are installed on the computer
when operating system is installed.
On other hand Application software are installed
according to user’s requirements.
5
User interaction As mentioned in above points system software are
specific to system hardware so less or no user
interaction available in case of system software.
On other hand in application software user can
interacts with it as user interface is available in this
case.
6
Dependency System software can run independently. It provides
platform for running application software.
On other hand in application software can’t run
independently. They can’t run without the presence
of system software..
7
Examples Some examples of system software’s are compiler,
assembler, debugger, driver, etc.
On other hand some examples of application
software’s are word processor, web browser, media
player, etc.
Difference between system software & Application Software: -
