This Presentation covers hole detailed explanation on Computer Software including Application Software and System Software with Examples.

2. COMPUTER SOFTWARE
Software refers to the non-tangible components
of computers, known as computer programs. Computer
software and hardware require each other and neither
can be realistically used without the other.

3. DIFFERENCE BETWEEN SYSTEM SOFTWARE
& APPLICATION SOFTWARE
System Software Application Software
Enables the computer to function
properly.
Usage
Enables users to work efficiently
with documentation such as letters,
accounting reports and
presentations.
Compulsory each computer must
have a system software to
function.
Need
Optional depends on usage and
needs. Without an application
software,
the computer is still able to
function.
Each computer only needs one
system software
Number Of
Software
Each computer can have more than
one application software.
Independent - system software
can function without an
application software.
Dependency
Dependent - application software
cannot work without system
software.

7. OPERATING SYSTEM
Disk Operating System
 The term DOS can refer to
any operating system, but it is
most often used as a shorthand
for MS-DOS(
Microsoft disk operating
system). Originally developed
by Microsoft for IBM, MS-DOS
was the standard operating
system for IBM-compatible
personal computers.
 DOS is still 16-bitoperating
system and does
not support multiple users or
multitasking.

8. OPERATING SYSTEM
Windows
Microsoft Windows is a series
of graphical interface operating
systems developed, marketed, and
sold by Microsoft.
Microsoft introduced an operating
environment named Windows on
November 20, 1985 as a
graphical operating system
shell for MS-DOS in response to the
growing interest in graphical user
interfaces (GUI).Microsoft Windows
came to dominate the world's personal
computer market with over 90%
market share, overtaking Mac OS,
which had been introduced in 1984.

9. UNIX
 Unix (officially
OPERATING SYSTEM
trademarked as UNIX) is
a multitasking, multi-user
computer operating
system that exists in many
variants. The original Unix
was developed
at AT&T's Bell
Labs research center
by Ken
Thompson, Dennis
Ritchie, and others.

10. TRANSLATORS
Interpreters
 A program that executes
instructions written in
a high-level language.

11. Compilers
TRANSLATORS
 A program that
translates source
code into object code.

12. DEBUGGERS
A special program used
to find errors (bugs) in
other programs. A
debugger allows
a programmer to stop a
program at any point and
examine and change the
values of variables.

13. ASSEMBLERS
A program that
translates programs
from assembly
language to machine
language.

14. FILE MANAGEMENT SYSTEM
The system that
an operating
system or program use
s to organize and keep
track of files. For
example,
a hierarchical file
system is one that
uses directories to
organize files into
a tree structure.

15. PACKAGES
Linkers
In computer science,
a linker or link
editor is a computer
program that takes one
or more object
files generated by
a compiler and
combines them into a
single executable prog
ram.
