operations
OBJECTIVE

COMPUTER
• an electronic device for
storing and processing
data, typically in binary
form.
• an electronic device that
can store, process, and
output information.

is hardware or software, input
or output devices base on the
photo presented.

COMPONENTS OF

SYSTEM
A. HARDWARE
B. SOFTWARE
C. DATA WARE
D. PEOPE WARE

A.
HARDWARE
Hardware is the
physical
components of a
computer

HARDWARE CATEGORIES
(Functional Parts)
1. Input devices
2. Output Devices

Input
devices
The Input devices are used by
the user to enter data,
commands and programs to
the computer.
Most common input devices
are:
Keyboard, mouse, trackball,
joystick, light pen, scanners
and digital cameras

Output
devices
An output device is any
information (data) that comes
out of a computer.
Most common output devices
are:
Monitor or Display, Printer and
speakers

B. SOFTWARE
refers to the intangible part of the
computer system that consists of routines
and programs, procedures and specialized
aids (for example, compilers and library
routines) that make the hardware
components perform their functions.

Computer software can be classified into
following categories:
is the basic software responsible for interacting
with the hardware. It is the foundation on which
user programs and application programs are
built.
Ex. include Microsoft Windows and macOS.
Operating system (OS)
is the catch-all name for all programs that are
used for carrying out specific tasks - office
document creation (word processor), pay roll
processing (spreadsheet), publisher etc.
Application programs
A utility program is a type of system software that
helps users manage and maintain their computer
system.
Ex. Security, Data backup, Antivirus software
Utility Programs

DATA WARE
The systematic and
organized collection of
data and procedures
relevant to the
organization

PEOPLE
WARE
Refers to personnel who
manage and use the computer
system, who design the
applications and systems
software, who write and
encode the programs and who
run the hardware.

Input is whatever goes into the
computer. Input can take a variety of
forms, from commands you enter by
keyboard to data from another
computer (via a network connection)
or device (via direct or network
connection). A device that feeds data
into a computer, such as a keyboard
or mouse, is called an input device.

Storage
Computer data storage is referred to as storage
or memory, which can save digital data.
Examples are RAM, hard disks, CDs, DVDs and
removable flash memory sticks.
Processing
The processor is the brain of a computer. It's
also called the CPU (Central processing unit)
and it is a microchip. For a non-programmer,
this is where all the real action is. Programs just
set the stage and direct the play. (In this off-
hand analogy, the play itself, in written form,
would be most like a program.)

Output is any information (data) that
comes out of a computer. Output
devices can be other computers,
display screens, speakers, and
printers.

Directions: Give 5 example of input, output,
hardware and software.
