Many of the todays basic functions are being simplified by technology.
Computers have been in at for front in development the innovations through its
many functions. In this digital world having the knowledge and skills in computer
system servicing (CSS) is the start and most fundamental.
Let us compare technology before and today.

21. Comparison
BEFORE AFTER

31. • Have you used your computer inside your schools or ICT laboratory?
• How do you use it?
• Did you use it to answer for you homework’s?
• Did you use it to edit the picture of your crush?
• Did you use it for entertainment?
• No matter how you use it. It is still important to understand the computer
system.
• As an aspiring computer technician, it is very important to know the
different components of a computer system.These are the hardware,
software and peopleware. Each component plays an important role,
without each other computer systems will not work properly.

48. ELEMENTS OFTHE COMPUTER SYSTEM
•COMPUTER SYSTEM is a collection of different parts
that are designed to receive, process, manage and
present meaningful information formats.
•HARDWARE
•SOFTWARE
•PEOPLEWARE

49. HARDWARE
•Computer hardware is the collection of physical
elements that constitutes a computer system.
Computer hardware refers to the physical parts or
components of a computer.
•Major hardware components of a computer
system.
•They are tangible and can be sense by touch.

50. The following list represents a basic set of
hardware found in most PCs.
• 1. System Unit- The main part of a microcomputer, sometimes
called the chassis.
• It includes the following parts:
• Motherboard, Microprocessor, Memory Chips, Buses, Ports,
Expansion Slots and Cards.
• A System unit is the brain of a computer. It is responsible for all
functions and processes.

51. Hardware has two categories:
•Input device is any peripheral (piece of computer
hardware equipment) to provide data and control signals
to an information processing system such as a computer
or other information appliance.
•Output device used to communicate the results of data
processing carried out by an information processing
system (such as a computer) which converts the
electronically generated information into human
readable form

52. FOUR COMPONENTS OF
HARDWARE DEVICE

53. Keyboard - the primary input device used to communicate
with the computer. A computer keyboard closely
resembles a conventional typewriter keyboard with the
addition of numerous keys that are used specifically for
computing functions.

54. Mouse -The mouse is another input device used to
point at objects on the computer monitor and select
them.

55. Touch Screen - A display screen that is sensitive to
the touch of a finger or stylus

56. Light Pen - A light-sensitive stylus wired to a video
terminal used to draw pictures or select menu
options.

57. DigitizerTablet - A graphics drawing tablet used for
sketching new images or tracing old ones. Also
called a "graphics tablet," the user contacts the
surface of the device with a wired or wireless pen or
puck.

58. Scanning Devices- A device that can read text or
illustrations printed on paper and translates the
information into a form which the computer can use

59. Microphone – It allows the user to speak to the
computer in order to record a voice message or
navigate software.

60. Web Camera – used in transmitting live
images over theWorldWideWeb

61. B. OUTPUT DEVICES (OD)
•Monitor - It displays
information in visual
form, using text and
graphics.The portion of
the monitor that
displays the information
is called the screen or
video display terminal.
There are 3 types of
Monitor these are the
CRT, LCD and LED
Monitors

62. LCD Projectors - utilize two
sheets of polarizing material
with a liquid crystal solution
between them. An electric
current passed through the
liquid causes the crystals to
align so that light cannot pass
through them. Each crystal,
therefore, is like a shutter,
either allowing light to pass
through or blocking the light.

63. Printer - A device that prints text or illustrations on
paper.There are different types of printer, these are
Ink-Jet or Bubble-Jet Printer, Laser Printer, LCD and
LED Printer, Line Printer andThermal Printer.

64. Speakers – It is used to play sound.They may
be built into the system unit or connected with
cables.

65. PROCESSING DEVICE (PD)
-are the components responsible for the
processing of information within the computer
system, it includes devices such us the CPU,
memory and mother board.

66. Mother board- is the main printed circuit board in general-
purpose computers and other expandable system. It holds
and allow communication between many of the crucial
electronic components of a system, such as the central
processing unit and memory, and provides connections for
other peripherals.

67. Central Processing Unit
(CPU)-a central processor,
main processor or just
processor, is the electronic
circuitry that executes
instructions compromising a
computer program. It
performs basic arithmetic,
logic, controlling, and
input/output operations
specified by the instructions
in the program. It is the brain
and heart of the computer.

68. Random Access Memory (RAM) -is a form of
computer memory that can be read and changed in
any order, typically used to store working data and
machine codes.

69. Read-Only Memory (ROM) – it
refers to computer memory chips
containing permanent or semi-
permanent data.
Unlike RAM, ROM is non-volatile;
even after you turn off your
computer, the contents of ROM will
remain.Almost every computer
comes with a small amount of ROM
containing the boot firmware.

70. STORAGE DEVICE (SD)
-are components which allow data to be stored
within a computer system.
-is any type of computing hardware that is used
for storing, porting or extending data files and
objects. Storage devices can hold and store
information both temporarily and permanently.
They maybe internal or external to a computer,
server or computing device.

71. Hard drive disk
– is the hardware
component that
stores all of your
digital content.

72. USB Flash Drives – is a
portable data storage
device.

73. Compact Disc (CDs) – is a digital optical disc
data storage format

74. Memory Card – a memory cartridge is an electronic
data storage device used for storing digital
information, typically using flash memory

75. SOFTWARE
The set of instructions (also called a program) that
guides the hardware to operate effectively.
It tells the computer what to do.
A set of instructions that directs a computer’s
hardware to perform a task is called a program, or
soft ware program.

76. Are you familiar with these pictures?
Yes these are software that we are familiar of.

77. Two types of Software
•System Software
•Application software

79. Operating software- is system that manages
computer hardware, software resources, and
provides common services for computer programs.

82. Application software- is a type of computer
program that performs a specific personal,
educational, and business functions. Each program
is designed to assist the user with a particular
process, which maybe related to productivity,
creativity and/ or communication.

84. FLOW OF COMPUTER OPERATION

86. Examples of Application Software:
Microsoft Products – Microsoft Office, Excel,Word,
Powerpoint, Outlook ,Photoshop etc.
Internet Browser – Firefox, safari and google
chrome.
Mobile pieces of software ( Spotify, Facebook,
Messenger etc.)

87. PEOPLEWARE
-can refer to anything that has to do with the role of
people in the development or use of computer
software and hardware systems, including such
issues as developer productivity, teamwork, group
dynamics, the psychology of programming, project
management, organizational factors, human
interface design, and human-machine- interaction.
It is the most important element of the computer.
