Составить аннотацию на для текста : central processing unit it is well-known in computer science that the words “computer” and “processor” are used interchangeably. speaking more precisely, “computer” refers to the central processing unit (cpu) together with an internal memory.the internal memory, control and processing components make up the heart of the computer system. manufactures design the cpu to control and carry out basic instructions for their particular computer. the cpu coordinates all the activities of the various components of the computer. it determines which operations should be carried out and in what order. the cpu controls the operation of the entire system by issuing commands to other parts of the system and by acting on responses. when required, it reads information from the memory, interprets instructions, per- forms operations on the data according to the instructions, writes the results back into the memory, and moves information between memory levels or through the input-output ports. in digital computers the cpu can be divided into two functional units called the control unit (cu) and the arithmetic-logic unit (alu). these two units are made up of electronic circuits with millions of switches that can be in one of two states, either on or off. the function of the cu within the central processor is to transmit coordi- nating control signals and commands. the control unit is that part of the com- puter that directs the sequence of step-by-step operations of the system, selects instructions and data from memory, interprets the program instructions, and controls the flow between main storage and the arithmetic-logic unit. the alu, on the other hand, is that part of the computer in which the actual arithmetic operations, namely, addition, subtraction, multiplication, division, and exponentiation, called for in the instructions are performed. programs and the data on which the cu and the alu operate, must be in internal memory in order to be processed. thus, if located in secondary memory devices, such as disks or tapes, programs and data are first loaded into internal memory.

Ann: I’m hungry, I want a big hamburger for lunch. What about you?

Bella: I don’t eat hamburgers. It is unhealthy food. Do you know I’m trying to lose weight? I go to a swimming pool three times a week, and I do morning exercises. I also drink about 2 litres of water a day and eat more fruits, herbs and vegetables.

Ann: Why do you try to lose your weight?  

Bella: My doctor told me that I should lead a healthy lifestyle because I can get a heart attack. It is better to eat small meals, and choose products based on fruit and vegetables, instead of fat, fried and sugary food.

Ann: So, what are you going to take for lunch?

Bella: Three-egg omelette, 1 red pepper, 1 small tomato, and a whole-wheat bun.

Ann: I like it. What do you eat for breakfast?

Bella: I eat 1 slice whole-grain bread with 2 slices low-fat cheese for breakfast. And of course I enjoy my cup of coffee. Then I can eat an apple or a pear before lunch.

Ann: Good idea! I think it’s very tasty. What do you prefer to drink?
