V. Give the situations from the text in which the following words and expressions are used:

1. the words computer and processor 6. located

2. the internal memory 7. first loaded

3. the function of control unit 8. primary components

4. components 9. high-speed binary adder

5. the arithmetical-logical unit 10. electronic circuitry

1. 
   It is common practice in computer science for the words ‘computer’ and ‘processor’ to be used interchangeably
   
2. 
   The internal memory, control and processing components make up the heart of the computer system
   
3. 
   The function of the control unit within the central processor is to transmit coordinating control signals and commands
   
4. 
   A control unit has the following components:
   
5. 
   The arithmetical-logical unit (ALU) is that portion of the computer in which the arithmetical operations, namely, addition, subtraction, multiplication, division and exponentiation, called for in the instructions are performed.
   
6. 
   ++++
   
7. 
   Thus, if located on secondary memory devices such as disks or tapes, programs and data are first loaded into internal memory.
   
8. 
   The primary components of the ALU are banks of bistable devices, which are called register.
   
9. 
   At the core of the arithmetical-logical unit is a very high-speed binary adder
   
10. 
    The logical unit consists of electronic circuitry,
    

1. More precisely, ‘computer’ refers ..... the central processing unit.

2. The CPU can also ..... information from memory and can ..... the result of manipulations back into ..... unit ..... later reference.

3. The control unit is that portion of the computer that ..... the sequence operations of the system, selects ..... and data ..... memory and controls the flow ..... main storage and the ALU.

4. Programs and the data on which the control unit and the ALU operate, must be in ..... to be processed.

5. At the core of the arithmetical-logical unit is a very high-speed.

6. Modern computers can ..... more than one hundred thousand additions ..... thirty-two bits within a second.

7. It is common practice in computer science ..... the words ‘computer’ and ‘processor’ to be used.
