LESSON STAGES

Introductionmf2d2e1da9099f93e_1528450127855_0Introduction

The task of the students before the lesson was to revise the components of a computer set which they had already learnt (a central processing unit, monitor, mouse, keyboard). They revise the components of a central processing unit.

The students watch a multimedia presentation prepared earlier. They specify the purpose and function of the particular components. The teacher completes the information.

Proceduremf2d2e1da9099f93e_1528446435040_0Procedure

[Slide show] The components of a central processing unit

motherboardmotherboardmotherboard is a  printed circuit board (PCB) on which the basic components of the computer are mounted, enabling their intercommunication. The crucial components of a computer system, such as the central processing unit or memory, are mounted directly on the motherboard or in specially prepared slotsslotsslots. The motherboard enables connecting additional components in the form of the so called expansion cards. It also provides connectors for the peripheral devicesperipheral devicesperipheral devices of the computer.

central processing unit (CPU)central processing unit (CPU)central processing unit (CPU) is the most important part of the computer.  It performs all calculations and controls the operation of the other units. It is usually designed as a single integrated circuitintegrated circuitintegrated circuit(nowadays it contains billions of transistorstransistorstransistors). As it produces a significant amount of heat, it must be equipped with a heatsinkheatsinkheatsink and a computer fancomputer fancomputer fan.

Task
List the best known producers of central processing units. You can refer to the Internet.

Memory refers to the basic computer data storage. Computer memory operates at a very high speed, contrary to mass storage, which operates at a lower speed, but offers definitely larger storing capacity. The following types of memory are used in the computer:
- random‑access memory (RAM)random‑access memory (RAM)random‑access memory (RAM) – it is used as the main memory (primary storage) of the computer. It provides the reading and writing of data. It is a volatile memory, which means that when the computer is restarted, the stored data is lost;
- read‑only memory (ROM)read‑only memory (ROM)read‑only memory (ROM) – it provides only the reading of data. It stores software that initiates the operation of the computer (BIOS).

An expansion cardexpansion cardexpansion card is an additional component of the computer structured on a  separate printed circuit boardprinted circuit boardprinted circuit board, mounted in a special connector of the motherboard, that adds a specified functionality to a computer system.
A video card enables displaying video on the screen of a computer monitor.
A sound card enables recording, processing and playing audio on the computer.
A network interface controller enables to connect the computer to the Internet.

Mass storagemass storageMass storage
Mass storage is a non‑volatile memory that enables storing large amounts of data for a long time. While the important parameter of primary storage is the speed of its operation, in the case of mass storage its speed is not as important as its storing capacity. The basic types of mass storage include:
- a hard disc drivehard disc drivehard disc drive – it uses a magnetic medium for reading and writing data,
- an optical disc drivoptical disc driveoptical disc drive - its uses laser light for reading and writing data,
- semiconductor memorysemiconductor memorysemiconductor memory – memory based on  integrated circuits (e.g. a pendrive, a solid‑state drive), which is characterised by significantly shorter access time.

A power supply unit is a device mounted inside a computer’s case that supplies various voltage values in order to power all devices of the computer. Laptops, tablets and smartphones are powered by a  battery, which enables their operation for several hours without power supply.

Task
List the types of non‑rewritable andrewritable optical disc drives.

Different parameters will be taken into account by a graphic designer, a fan of computer games or a person who uses the computer for office work.mf2d2e1da9099f93e_1527752263647_0The selection of the units of a computer depends primarily on its purpose.
