This document is a self-access learning module on computer hardware peripherals for secondary school students in Malaysia. It aims to teach students about peripherals, which are external devices that can be attached to a computer. The module defines peripherals and categorizes them into input devices, output devices, and storage devices. It provides examples of different types of peripherals such as printers, scanners, projectors, digital cameras, CD drives, and external storage devices. It also explains the functions of each peripheral type. The module contains activities for students to identify peripherals from images and learn their definitions and functions.

Activity 1:
Definition & types of peripheral
Peripheral Device
External hardware devices attached to the computer
are called peripheral devices
There are three types of peripheral devices :
• Input devices
• Output devices
• Storage devices
Figure 1: Peripheral Device
Input Devices
Input devices are any electronic device that are connected to a computer and produces
input signals.
Figure 2: Input Device
Output Devices
Output is the result of data processing activity when it is presented externally to the
system. The output from a computer can be printed or displayed form .
An output device is hardware that is capable of delivering or showing information to one or
more users. An output device shows, prints and presents the results of a computer’s work.

Storage Devices
Information and documents are stored in a computer storage so that it can be retrieved
whenever they are needed later on.
Computer storage is the holding of data in an electromagnetic form for access by a
computer processor.
Hard Disk

Diskette
CD Rom
Thumb Drive
Different types and the functions of peripheral
1. Printers
A printer is another example of an output device that can be used to print text and graphics
on mediums such as paper, transparency film or even cloths.
Figure 3: Printer
A photo printer is a colour printer that produces photo quality pictures.
An image setter produces high quality output compared to an ordinary laser printer. An
image setter is a high resolution output device that can transfer electronic text and graphics
directly to film, plates, or photo-sensitive paper.

2. Scanners
In computing, a scanner is a device that analyzes images, printed text, handwriting, or
objects (such as an ornament) and converts it into a digital image.
These are examples of scanners:
a. The flatbed scanner is the most common in offices.
b. Hand-held scanners are no longer used due to the difficulty in obtaining a highquality image.
c. Digital camera scanners, that are based on the concept of reprographic cameras.
d. Planetary scanners, which take photographs of books and documents
e. 3D scanners, for producing three-dimensional models of objects,
Planetary and 3D scanners are considerably more expensive than other types of scanners.

3. LCD Projector
LCD projector is a type of video projector for displaying video, images or computer data on
a screen or other flat surface. It is a modern equivalent of the slide projector or overhead
projector.
A Liquid Crystal Display (LCD) projector uses its own light source to project what is
displayed on the computer onto a wall or projection screen. A digital light processing (DLP)
projector uses tiny mirrors to reflect light that can be seen clearly in a well-lit room.

4. Digital Cameras
Digital Cameras are electronic devices used to capture and store photographs digitally,
using the memory card without using photographic film like conventional cameras, or
recording images in an analog format to magnetic tape like many video cameras.
Modern compact digital cameras are typically multifunctional, with some devices capable of
recording sound and/or video as well as photographs.

5. External CD Drives
The external DVD/CD-RW combo drive functions as a DVD player, a CD-RW drive and a
CD-ROM drive. This allows you to install computer applications, files, music and movies on
CD. It is easy to be carried around.

6. External Storages
External storage is an alternative storage. It is very useful to store programs and data for
future use. The storage is required for two reasons:
1. The working memory of the CPU is limited in size and cannot always hold the amount of
data required.
2. Data and programmes in storage do not disappear when the power is turned off.
