1. THE COMPUTER
BY:Myth Lisayan

2. Definition
an electronic device for storing and
processing data, typically in binary
form, according to instructions given
to it in a variable program.

3. FUNCTION
 There are basically for basic functions of
computers - input, storage, processing and
output. These are described below: Input:
Receiving or accepting information from outside
sources. The most common way of performing this
function is through the information entered
through the keyboard and the click of mouse

4. INPUT DEVICES
A computer mouse is a pointing device that
detects two-dimensional motion relative to
a surface.
Keyboard
A computer keyboard is a typewriter-style
device which uses an arrangement of
buttons or keys to act as a mechanical
lever or electronic switch.
Mouse:
Joystick: A joystick is an input device consisting of a
stick that pivots on a base and reports its
angle or direction to the device it is
controlling
Scanner:
Scanner Pro is the best app for quickly
scanning and saving a digital version of
a paper document.

5. a piece of electrical equipment through which recorded or
broadcast sound can be heard:
Speaker:
Projector: projector or image projector is an
optical device that projects an image
(or moving images) onto a surface,
commonly a projection screen.
In computing, a printer is a peripheral
which makes a persistent human-readable
representation of graphics or text on
paper or similar physical media
Printer:
OUTPUT DEVICE

6. Types of computer
Minicomputer:
Tower:
A desktop computer is a personal
computer designed for regular use at a
single location on or near a desk or table
due to its size and power requirements.
Desktop computer:
A supercomputer is a computer that
performs at or near the currently highest
operational rate for computers.
Supercomputer:
A minicomputer is a type of computer that
possesses most of the features and
capabilities of a large computer but is
smaller in physical size.
Most desktop PCs sold today are built in
the tower form

7. Types of computer
Mainframe computers (colloquially
referred to as "big iron"[1]) are computers
used primarily by large organizations for
critical applications.
Mainframe computer:
Laptop: A laptop, often called a notebook or
"notebook computer",
A microcomputer is a small, relatively
inexpensive computer with a
microprocessor .
Microcomputer:
A small vertical case for a computer, or a
computer mounted in such a case.
Minitower:

8. Types of computer
A server is a computer program that
provides services to other computer
programs (and their users) in the
same or other computers.
Server:
A personal computer (PC) is a multi-
purpose electronic computer whose size,
capabilities, and price make it feasible for
individual use.
Personal computer:

9. Computer networks
 A computer network is a set of computers
connected together for the purpose of
sharing resources. The most common
resource shared today is connection to the
Internet. Other shared resources can include
a printer or a file server.

10. Transmission media
Transmission media is a pathway that
carries the information from sender to
receiver. We use different types of
cables or waves to transmit data. Data
is transmitted normally through
electrical or electromagnetic signals.

11. Types of Transmission Media
Twisted pair cabling is a type of wiring in
which two conductors of a single circuit
are twisted together for the purposes of
canceling
Twisted pair:
Coaxial cable, or coax pronounced is a
type of electrical cable that has an inner
conductor surrounded by a tubular
insulating layer.
Coaxial
cable:
An optical fiber or optical fibre is a
flexible, transparent fiber made by
drawing glass (silica) or plastic to a
diameter.
optical fibre:

12. Major Parts of The Computer
A motherboard (sometimes alternatively
known as the mainboard, system board,
baseboard, planar board or logic
Motherboard:
A central processing unit (CPU) is the
electronic circuitry within a computer
that carries out the instructions of a
computer program.
Central processing unit:
Random-access memory (RAM /ræm/) is a
form of computer data storage which
stores frequently used program
instructions to increase the general speed
of a system
Random-access memory:

13. Major Parts of The Computer
Hard disk drive:
hard disk drive (HDD), hard disk, hard
drive or fixed disk[b] is a data storage
device that uses magnetic storage to store
and retrieve digital information using one
or more rigid rapidly rotating disks
(platters) coated with magnetic material.
Power supply: A power supply is an electronic device that
supplies electric energy to an electrical
load. The primary function of a power
supply is to convert one form of electrical
energy to another.
