Activity 1: Definition & types of peripheral PERIPHERAL DEVICE A peripheral is a piece of computer hardware that is added to a host computer ,i.e any hardware except the computer, in order to expand its abilities. More specifically, the term is used to describe those devices that are optional in nature, as opposed to hardware that is either demanded or always required in principle. External hardware devices attached to the computer are called peripheral equipments. There are three types of peripheral: • Input devices • Output devices • Storage devices INPUT DEVICES Input devices are any electronic device connected to a computer and produces input signals.

OUTPUT

DEVICES

Output is the result of data processing activity when it is presented external to the system. The output from a computer can be in a form for use by people, for example, printed or displayed. 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 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.

Activity 2: Different types & the function of peripheral 1. Printers A printer is another example of an output device that can be used to print text, apart from graphics, on mediums such as paper, transparency film or even cloths.

A photo printer is a colour printer that produces photo-lab-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 5

ICTL For Secondary School - HARDWARE Module

In computing, a scanner is a device that analyzes images, printed text, or handwriting, or an object (such as an ornament) and converts it to a digital image. The flatbed scanner is the most common in offices. Hand-held scanners, where the device is moved by hand, were briefly popular but are now not used due to the difficulty of obtaining a high-quality image. Other types of scanners are planetary scanners, which take photographs of books and documents, and 3D scanners, for producing three-dimensional models of objects, but these types of scanner are considerably more expensive than other types of scanners. Another category of scanner are digital camera scanners, which are based on the concept of reprographic cameras. ( source http://en.wikipedia.org/wiki/Image_scanner)

3. LCD Projector

An 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 on a wall or projection screen. A digital light processing (DLP) projector uses tiny mirrors to reflect light which can be seen clearly in a welllit room.

4. Digital cameras A digital camera is an electronic device used to capture and store photographs digitally, instead of 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 programs in storage do not disappear when the power is turned off.
