2) Read the definitions and write the suitable word:

a) The physical units which make up a computer system.

b) The set of program instructions that tell the computer what to do.

c) The processor chip that performs the basic operations of a computer; its basic components are the control unit, the arithmetic logic unit and the registers.

d) The units connected to the computer classified into three types.

e) There are two types of this section which holds the instructions and data currently being processed.

3) Fill in the prepositions:

The computer performs a set… instructions. Storage devices provide a permanent storage … data and programs. We use disk drivers to read and write data…. disks. Input devices enable data to go …. computer’s memory. The most common input devices used all…..the world are the mouse and the keyboard. Output devices extract the finished product …. the system and show information ….the screen or print the results …..the printer. …. the rear panel … the computer there are several ports …. a modem, a digital camera, a scanner etc. They allow communication ….. the computer and the devices. …. the front panel … modern desktop PCs there are USB ports and memory card readers. You can extract data ….computer very quickly ……flashcard.

4) Are the sentences true or false? Correct the sentences:

The main part of computer is the peripherals.

The function of the central processing unit is to execute program instructions and coordinate them.

The disk drivers enable data to go into computer’s memory.

On the rear panel of the computer there is only one port.

The main memory is a collection of RAM chips.

Unit 4. What is inside a pc system?

Vocabulary.

To measure- измерять

To expand – расширять

To contain -содержать

To handle - вручать, управлять, обрабатывать

The rest of - остальное

To register - зарегистрировать

To cause - стать причиной, вызывать

The nerve center of a PC is the processor, also called the CPU, or central processing unit which is built into a single chip. It executes program instructions and coordinates the activities. It is a small piece of silicon with a complex electrical circuit called an integrated circuit.

The processor consists of three main parts;

-the control unit

-the arithmetic logic unit performs mathematical calculations and logical operations

-the registers for storing and controlling data. One of the registers keeps track of the next instruction to be performed. The other holds the executed instruction.

The power and performance of a computer is partly determined by the speed of its processor. A system clock sends out signals at fixed intervals to measure and synchronize the flow of data. Clock speed is measured in gigahertz.

The programs and data must be loaded into the main memory therefore when we run the CPU looks for it on the hard disk and transfers the copy into the RAM chips. RAM, in other words random access memory, is volatile. It means that information is lost when we turn on the computer. However, ROM, or read only memory, is non-volatile. It contains instructions and routines for operations.

The BIOS means basic input/output system and uses ROM to control communication with peripherals. We can also expand RAM capacity and add extra chips.

The main circuit board inside your computer is called the motherboard and contains the processor, the memory chips, expansion slots, controllers for peripherals which are connected by buses. Buses are electrical channels which allow devices to communicate with each other. The size of the bus is called bus width and determines how much data can be transmitted- the larger the width, the more data can travel along the bus.

Expansion slots allow users to install expansion cards for example network, sound, memory and video cards.

Answer the questions according to the text:

  1. What parts does computer consist of?

  2. What does the ROM mean?

  3. What does the RAM mean?

  4. What do “buses” mean in the computer?

  5. How can we wide the possibility of our computer?
