LESSON STAGES

Introductionm70bcb5bf91a2ac92_1528450127855_0Introduction

The teacher initiates a discussion. The students revise the components of a computer set which they have already learnt (a central processing unit, monitor, mouse, keyboard). Together they answer the question: Which of them is the most important?

Definition:
A central processing unit is the most important part of a computer set. Depending on its architecture, it contains in a common case a power supply, a motherboard with a processor, a hard disc drive with the operating system and the main memory (RAM) as well as communication ports for other components of the set.m70bcb5bf91a2ac92_1527752256679_0A central processing unit is the most important part of a computer set.

Definition:
A peripheral deviceperipheral deviceperipheral device is any part of the computer other than the processor and the main memory, e.g. a keyboard, monitor, mouse, printer, image scannerimage scannerimage scanner, computer speaker, microphone etc.

Procedurem70bcb5bf91a2ac92_1528446435040_0Procedure

Various peripheral devices, which expand the features of the computer, can be connected to the central processing unit. They can be connected with special cables or wirelessly, e.g. via BluetoothbluetoothBluetooth or Wi‑FiWi‑FiWi‑Fi.

BluetoothbluetoothBluetooth
Bluetooth is a wireless communication using short‑wavelength radio waves. It is used for exchanging data between various electronic devices such as a keyboard, computer, smartphone etc.

Wi‑FiWi‑FiWi‑Fi
Wi‑Fi is a wireless communication using long‑wavelength radio waves (from several metres to several kilometres). It is used mainly for wireless local area networking. Wi‑Fi is the abbreviation of Wireless Fidelity.

Task 1

Initiate a brainstorming session about peripheral devices in your group. How many peripheral devices can you name? With what medium can they be connected to the computer? What are their functions?

Task 2

By using a search engine find images presenting peripheral devices that you know as well as short information about them. Present the results of your work in a text editor.

External disc driveexternal disc driveExternal disc drive
An external disc drive is used for data storing.

Microphone
A microphone is a device that enables to input audio signals into the computer, e.g. during speech recording or a voice call over the internet.

Projector
A projector (image projector) is a device that enables displaying images on a projection screen.

Image scannerimage scannerImage scanner
An image scanner (scanner) is a device that scans documents and images printed on paper and converts them to digital images.

Graphic tablet
A graphic tablet is used for creating images and graphics that are input into the computer by hand‑drawing them with a special pen.

PlotterplotterPlotter
A plotter is a device similar to a printer, but it is possible to print on it images in a very large format, e.g. posters, maps etc.

3D printer3D printer3D printer
A 3D printer is a device that enables creating three‑dimensional objects.

Interactive whiteboardinteractive whiteboardInteractive whiteboard
An interactive whiteboard is a whiteboard connected to the computer and a multimedia projector. It combines the function of a display, a whiteboard and a large touchscreen.
