3. SYSTEM
SOFTWARE• System software,
or systems software,
is computer
software designed to
provide a platform to
other software. Examples
of system software include
operating
systems, computational
science software, game
engines, industrial
automation, and software
as a service applications.[
4. TYPES OF SYSTEM SOFTWARE:
OPERATING SYSTEM (OS)
DEVICE DRIVERS
UTILITY PROGRAMS
LANGUAGE PROCESSORS
5. OPERATING
SYSTEM (OS)
THE OPERATING SYSTEM (OS) IS THE
MOST IMPORTANT PROGRAM THAT
RUNS ON A COMPUTER. EVERY
GENERAL-PURPOSE COMPUTER MUST
HAVE AN OPERATING SYSTEM TO
RUN OTHER PROGRAMS
AND APPLICATIONS. COMPUTER
OPERATING SYSTEMS PERFORM BASIC
TASKS, SUCH AS RECOGNIZING INPUT
FROM THE KEYBOARD, SENDING
OUTPUT TO THE DISPLAY SCREEN,
KEEPING TRACK OF FILES AND
DIRECTORIES ON THE STORAGE
DRIVES, AND
CONTROLLING PERIPHERAL DEVICES,
SUCH AS PRINTERS.
6. 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.[1] A DRIVER
PROVIDES A SOFTWARE
INTERFACE TO HARDWARE
DEVICES, ENABLING
OPERATING SYSTEMS AND
OTHER COMPUTER PROGRAMS
TO ACCESS HARDWARE
FUNCTIONS WITHOUT
NEEDING TO KNOW PRECISE
DETAILS OF THE HARDWARE
BEING USED.
7. UTILITY PROGRAMS
• A program that p
erforms a specific
task related to the
management of c
omputer function
s,
resources, or files,
as password prot
ection, memory m
anagement, virus
protection, and
file compression.
8. LANGUAGE PROCESSOR
A LANGUAGE PROCESSOR IS A SOFTWARE PROGRAM DESIGNED
OR USED TO PERFORM TASKS, SUCH AS PROCESSING PROGRAM
CODE TO MACHINE CODE. LANGUAGE PROCESSORS ARE FOUND IN
LANGUAGES SUCH AS FORTRAN AND COBOL.
9. APPLICATION
SOFTWARE
AN APPLICATION
PROGRAM (APP OR APPLICATION FOR SHORT) IS
A COMPUTER PROGRAM DESIGNED TO PERFORM A
GROUP OF COORDINATED FUNCTIONS, TASKS, OR
ACTIVITIES FOR THE BENEFIT OF THE USER. EXAMPLES
OF AN APPLICATION INCLUDE A WORD PROCESSOR,
A SPREADSHEET, AN ACCOUNTING APPLICATION,
A WEB BROWSER, A MEDIA PLAYER, AN
AERONAUTICAL FLIGHT SIMULATOR, A CONSOLE
GAME OR A PHOTO EDITOR. THE COLLECTIV NOUN
APPLICATION SOFTWARE REFERS TO ALL
APPLICATIONS COLLECTIVELY. THIS CONTRASTS
WITH SYSTEM SOFTWARE, WHICH IS MAINLY
INVOLVED WITH RUNNING THE COMPUTER.
10. APPLICATION SOFTWARE
AND ITS TYPES
Application Software Type Examples
Word processing software MS Word,
WordPad and Notepad.
Database software
Oracle, MS Access etc.
Spreadsheet software Numbers, Microsoft
Excel
Multimedia software Real Player, Media Player.
11. QUICK STYLES
• A word processor is an
electronic device or
computer software
application that performs
the task of composing,
editing, formatting, and
printing of documents.
12. DATABASE
A DATABASE IS AN ORGANIZED COLLECTION
OF DATA.[1] A RELATIONAL DATABASE, MORE
RESTRICTIVELY, IS A COLLECTION
OF SCHEMAS, TABLES, QUERIES, REPORTS, VIEWS,
AND OTHER ELEMENTS. DATABASE DESIGNERS
TYPICALLY ORGANIZE THE DATA TO MODEL
ASPECTS OF REALITY IN A WAY THAT
SUPPORTS PROCESSES REQUIRING INFORMATION,
SUCH AS (FOR EXAMPLE) MODELING THE
AVAILABILITY OF ROOMS IN HOTELS IN A WAY
THAT SUPPORTS FINDING A HOTEL WITH
VACANCIES.
13. SPREADSHEET SOFTWARE• A spreadsheet is an
interactive computer
application for organization,
analysis and storage
of data in tabular form.[1][2][3]Sprea
dsheets are developed as
computerized simulations of
paper
accounting worksheets.[4] The
program operates on data
entered in cells of a table. Each
cell may contain either numeric or
text data, or the results
of formulas that automatically
calculate and display a value
based on the contents of other
cells. A spreadsheet may also refer
to one such electronic
document.[5][6][7]
• Everything you add into the layout
placeholders is arranged perfectly
for you.
14. MULTIMEDIA
• Multimedia is content that
uses a combination of
different content forms such
as text, audio, images,
animations, video
and interactive content.
Multimedia contrasts
with media that use only
rudimentary computer
displays such as text-only or
traditional forms of printed
or hand-produced materia.
