4. The Elements of Computer System
A computer system is a collection of entities that are
designed to receive, process, manage, and present
information in a meaningful format. It has 3 elements that
will make a computer really useful.
Elements of a
Computer System
Hardware Software Peopleware

5. 1. Hardware
refers to the physical, tangible computer equipment and devices
which provides support for major functions such as input,
process, output and storage.
Components of
Computer Hardware
Input Device Output Device
Process Device Storage Device

6. A. INPUT DEVICES
are composed of a device that accepts data and instructions from
the user or from another computer system
Keyboard Microphone
Scanner
Mouse

7. B. OUTPUT DEVICE
is any piece of computer hardware that displays results after the computer has
processed the input data that has been entered.
Monitor Printer Speaker Projector

8. C. PROCESS DEVICE
is the computer’s circuitry in the system unit. It plays an important role in
processing operations. It is used to process data, using instructions from the
program.
C.1. Motherboard /
Mainboard / System Board –
is the main circuit board of a
computer. It contains all the
circuits and components that
run the computer.

9. C.2. CPU (CENTRAL
PROCESSING UNIT) -
The processor is the main
“brain” or “heart” of a
computer system. It
performs all of the
instructions and
calculations that are
needed and manages the
flow of information through
a computer.

10. C.3. RAM – (RANDOM
ACCESS MEMORY) RAM
is volatile, meaning it holds
data only when the power is on.
When the power is off, RAM's
contents are lost.

11. C.4.VIDEO CARD/GPU
(GRAPHICS
PROCESSING UNIT)
- also called a display card,
graphics card, display
adapter, or graphics adapter
is an expansion card which
generates a feed of output
images to a display device
(such as a computer
monitor).

12. D. STORAGE DEVICE.
stores data and programs.These hold data, information, and
programs permanently

13. 2. Software
– this term refers to the collection of
electronic instructions that tells the
computer what to do. It is a computer
program that is installed in your computer.

15. Kinds of Computer Software
A. System Software coordinates the activities and functions of
hardware and software. It controls the operations of computer
hardware and provides an environment or platform for all the
other types of software to work in. It is the most basic type of
software in any computer system, which is essential for other
programs, applications and the whole computer system to
function
A. System Software

16. A.1. Operating System
– is the program that, after being initially loaded into computer by a boot
program, manages all the other programs in a computer.
Examples– Microsoft Windows, Mac OS, Linux, Ubuntu

17. A.2. Utility Programs
– are small, powerful programs with a limited capability, they
are usually operated by the user to maintain a smooth running
of the computer system.

18. B. Application Software
is a computer program that performs a specific task. (Application
software
examples – MS Office, OpenOffice, Media Players, MS Access,
educational software, media development software, Antivirus
software, etc.)

19. 3. Peopleware
– the most important element of a computer system is its
users.
The following types of people interact with a computer system:
a. System Analysts - are people who design the operation and processing of
the system
b. System Programmers – are people who write codes and programs to
implement the working of the system.
c. System Operators – are people who operate the system and use it for
different purposes. Also called the end users like students, teachers, and
other professionals.

20. “Filling to know”
System Software coordinates the activities and functions
of hardware and software. It controls the operations of
computer hardware and provides an environment or
platform for all the other types of software to work in. It
is the most basic type of software in any computer
system, which is essential for other programs,
applications and the whole computer system to function
