Definition
SOFTWARES-
Are programs that make a computer to run.
They are sets of instructions which tell the
computer what to do to come up with the
desired result.

Application Software
• Application software makes computer popular and easy to use
• Application software can also be stored on CDs, DVDs, and
flash or keychain storage devices
• Application software
Programs that help users solve particular computing
problems
Def: 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.

• Common application software:
 Microsoft Word
 PowerPoint
 Netscape, Internet Explorer
 Photoshop, Photo-Paint
 Dreamweaver

• Communicate from home with computer
at office
• Access data stored in another computer
in another location
• Stock exchange updates
• Weather information

Communications
• Provides method for
communicating
between computers
• Most likely way to
connect is via the
Internet
• Use a browser to
access the Internet

Office Suites
• Group of basic software applications designed to
work together
• Data is portable between basic applications of
the suite
• Various applications in the suite have the same
“look and feel”
• Cost of suite is less than purchasing individual
applications

System Software
• System software is any computer software
which manages and controls the hardware so
that application software can perform a task.
• System software enables the application
software to interact with the computer
hardware.

System Software
• System software is background software that
helps the computer manage it’s own internal
resources.
• System software are generally prepared by
computer manufactures.
• System software serves as the interface
between hardware and the end users.

Features of system software
• Close to system
• Fast in speed
• Difficult to design
• Difficult to understand
• Less interactive
• Smaller in size
• Difficult to manipulate

Types of systems software
• Operating systems
• Utility programs
• Device Drivers

Operating systems
• Operating system (OS): set of programs that
coordinate computer resources,provide an
interface between users and the computer &
run applications.
• Operating System is a software, which makes a
computer to actually work.
• Examples: Windows, Linux, Unix and Mac OS,
etc.

Activities performed by the operating
system
1. Perform common computer hardware functions
2. Provide a user interface and input/output
management
3. Provide a degree of hardware independence
4. Manage system memory
5. Manage processing tasks
6. Provide networking capability
7. Control access to system resources
8. Manage files

Utilities
• Perform specific tasks related to managing
computer resources.
• Example :
1) Disk Defragmenter:
• it locates & eliminate unnecessary file
fragments & rearranges files & unused disk
space to optimize computer operations.

Utilities
2) Antivirus Software(programs):
Guard your computer system against viruses
that can invade(attack) your computer system.
3) Uninstall programs:
Allow you to safely & completely remove
unneeded programs & related files from hard
disk.

Utilities
4) Backup Programs:
That make copies of files to be used in case the
originals are lost or damaged.
5) File Compression Programs
That reduce the size of files so they require less
storage space 7 can be sent more efficiently
over the Internet.

6) Troubleshooting or diagnostic Programs:
That recognize and correct problems, ideally
before they become serious.

Device Drivers
• These are specialized programs designed to allow
particular input or output devices to communicate
with the rest of the computer system.
• A device driver (commonly referred to simply as a
driver) is a computer program that operates or
controls a particular type of device that is attached
to a computer.
• A driver provides a software interface to hardware
devices, enabling operating systems and other
computer programs to access hardware functions
