Software includes programs and instructions that control hardware but cannot be touched. There are two main types: application programs that perform tasks like word processing, and operating systems that manage hardware and allow application programs to function. Hardware are the physical devices of a computer like the CPU that processes data, input devices like keyboards and mice to enter data, and output devices like monitors and printers that display or print results.

1. PARTS OF A
COMPUTER
(HARDWARE AND SOFTWARE)

2. The SOFTWARE is set of simple
computer instructions or programs
used to manipulate or control the
hardware. These instructions are
written in programming languages.

3. SOFTWAREIS A PART OF COMPUTERTHAT
WE CANNOTTOUCH WITH OUR HAND BUT
CAN BE MANIPULATEDBY USING
HARDWARE.

4. Soft ware is the system, utility and
application program expressed in
machine language inside your computer.

5. Software is classified into two:
•APPLICATION PROGRAMS
•OPERATING SYSTEM

6. APPLICATIONPROGRAMS- performspecific
tasks.
E.g. Wor d processingprograms,
spreadsheetprograms,presentation
programs,gamesand simulatorprograms.
OPERATINGSYSTEM-is the basic software
requiredwhichmanages the hardware,
memory,storage device, clocksettingsand
others.
E.g. MS-dos,microsoftwindows95, OS/2
and the macintoshsystem.

7. The HARDWARE is all the electronic
devices of a computer system, such
as the equipment and its
peripherals.

8. INPUT DEVICES are used to
enter data, instruction and
programs to the computer
using commands.

9. KEYBOARD-isusedtoentertextdata.

11. Trackball-it is serves as the
mouse on laptops.

12.  Other input devices:

13. Processing devices-processed
data and information fed bye
the programmer.

14. CPU- is known as the brain of
the computer. It performs
arithmetic and logical
calculations and controls the
operations of other parts of thr
computer

15. CPU
CENTRAL PROCESSING UNIT

16. OUTPUT DEVICES- are
computer peripherals that
send information back to the
programmer in the form of
visual presentation, video
cassette, printed pictures and
printed papers.

17. Printer- an OD in which the
computer can directly send the
data to obtain hard copy print
outs of the results in the form
of black and white paper.

18. PRINTER

19. MONITOR- is where the text as
well as picture in black and
white or colored are seen.
