Unit 3 Inside the system

2 What is inside a PC system

A

1. 
   Control unit ,arithmetic logic unit , registers
   
2. 
   ALU performs mathematical calculations and logical operations
   
3. 
   A systemclock sent out signals at fixed intervals to measure and synchronize the flow data
   
4. 
   A thousand million herth
   
5. 
   RAM ( Random access memory ) is volatile
   
6. 
   ROM ( read only memory) is non- volatile , containing instructions and routines for the basic operations of CPU
   
7. 
   RAM capacity can be expanded by adding extra chips
   
8. 
   The main circuit board inside your system is called the motherboard and contains the processor , the memory chips expansions slots and controllers for peripherals
   
9. 
   Buses –electrical channels which allow devices inside the computer to communicate with each other
   
10. 
    Expansion slots allow users to install expansion cards adding feature like sound ,memory and network capabilities

3.Language work

1. which 4. which

2. that 5.that

3. who 6. Who

4. How memory is measured

A

1. Binary system made of just two numbers

2. Bits are grouped into eight- digit codes that typically represent characters ( letters , number and symbols)

3.Eight bits together called a Byte

4. Computer use standard code for the binary representation of character. This is the American Standard Code for Information Interchange( ASCII )

5. In order to avoid complex calculations of bytes , we use bigger units such as kilobytes , megabytes , gigabytes

B 1. Terabytes 4. Gigabytes

2. Megabytes 5.Byte

3. Kilobytes

5. a PC System

1. software 6.input devices

2. hardware 7. Storage devices

3. CPU 8. mouse

4.peripherals 9. monitor

5. RAM 10. Hard drives

6. Your ideal computer system

In my opinion , Everybody wants to have their own computer . As for me , Ihave a laptop . Its memory os 500GB . It contains of monitor keyboard and mouse area. it is very comfortable for me. I can go on the internet and download useful things for my study.
