3.1 Technical specifications

B. In pairs, answer these questions. If necessary, look at the Glossary.

1.What is the main function or a computer’s processor?

>> The main function of a computer’s processor is to process the instructions proviđe by the software; it also coordinates the acticves of the other units.

2.What unit of frequency is used to measure processor speed?

>>The gigahert(GHz). 1 GHz is equivalent to 1000MHz

3.What does RAM stand for?

>> Ram stands for random access memory

3.2 What is inside a PC system?

A. Read the extract “What is inside a PC” below and then answer these questions.

1. What are the three main parts of the CPU?

>> The Control Unit, the ALU and the registers.

2. What does ALU stand for? What does it do?

>>Arithmetic logic unit,; it performs mathematical caculations and logical operations.

3. What is the function of the system clock?

>>To measure and synchronize the flow of data.

4. How much is one gigahertz?

>> One thousand million hertz, or cycles, per second

5. What type of memory is temporary?

>> Ram

6. What type of memory is permanent and includes instructions needed by the CPU?

>>Rom

7. How can RAM be increased?

>>By adding extra chips, usually contained in a small circuit board called a DIMM

8. What technical term is used to refer to the main printed circuit board?

>>Motherboard

9. What is a bus?

>> An electrical path or channel that allows devices to communicate with each other.

10. What is the benefit of having expansion slots?

>> They allow you to install expansion cards(for example, sound, memory or network cards).

 B . Look at the extract again . What do the words in bold refer to?

1 This is built into a single chip… (line 2) the CPU, or central processing unit

2 … which executes program instructions and coordinates … (line 2) a single chip

3 … that is being executed.(line 15) the instruction

4 …performance of a computer is partly determined by the speed of its processor.(line17) the computer’s

5…. the CPU looks for it on the hard disk ( line 24) a program

6…. inside the computer to communicate with each other. (line 34) devices

3.3 Language work

A. Look at the HELP box below and then complete the following sentences with suitable relative pronouns. Give alternative options if possible. Put brackets round the relative pronouns you can leave out.

1 That’s the computer___which______I’d like to buy

2 .Core 2 Duo is a new Intel processor __which___contains about 291 million transistors.

3 .A webmaster is a person____who______ designs, develops and maintains a website.

4 A bus is an electronic pathway___which____carries signals between computer devices.

5 Here’s the DVD___which______ you lent me!

6 Last night I met someone___who_____works for GM as a software engineer.

3.4 How memory is measured?

A Read the text below and then answer the following questions.

1.How many digits does a binary system use?

>> A binary system uses two digits: 0 and 1. Switches inside a computer can only be in one of two possible states: OFF or ON. To represent these two conditions, we use binary notation.  0 means OFF and 1 means ON.

2.What is a bit?

>> Each 0 or 1 called a binary digit or bit

3.What is a collection of eights bits called?

>>A byte

4.What does ASCII stand for?

>>American Standard Code for information interchange

5.What is the purpose of ASCII?

>>To provide a standard system for the representation of characters.

B Complete these descriptions with the correct unit of memory.

1. A __terabyte_______is about one trillion bytes – about as much text as the books and magazines in a huge library.
2. A ___megabyte____is about one million bytes – about as much text as a 300-page novel.
3. A _____kilobyte________is about one thousand bytes – equivalent to one sheet of A4.
4. A _____gigabyte______is about one billion bytes – about as much text as 1,000 books.
5. A ______byte______can store a single character, such as the letter h or number 7.
