Прочитайте текст о структуре процессора и запол- ните пропуски, используя слова, ниже: structure of the processor the processor consists of a which is a circuit board on which are mounted chips, memory chips, and other components linked together by lines or channels in the form of control, address, and data in addition, a processor has which are electronic circuits providing specialized functions such as graphics, or which connect a system board to the system board also consists of electronic devices, such as an electronic for controlling the speed of operation; which store numeric data, during the course of processing; and various including sequence control register, address register, and function register. adaptor boards, registers, microprocessor, clock, сonductive, system board, accumulators, input or output devices, buses the central processing unit it is common practice in computer science for the words "computer" and "processor" to be used interchangeably. more precisely, "computer" refers to the central processing unit (cpu) together with an internal memory. the internal memory or main storage, control and processing components make up the heart of the computer system. manufacturers 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 can also retrieve information from memory and can store the results of manipulations back into the memory unit for later reference. in digital computers the cpu can be divided into two functional units called the control unit (cu) and the arithmetic-logical 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 control unit within the central processor is to transmit coordinating control signals and commands. the control unit is that portion of the computer that directs the sequence or 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-logical unit. the arithmetic-logical unit, on the other hand, is that portion of the computer in which the actual arithmetic operations, namely, addition, subtraction, multiplication, division and exponentation, called for in the instructions are performed. it also performs some kinds of logical operations such as comparing or selecting information. all the operations of the alu are under the direction of the control unit. programs and the data on which the control unit and the alu operate, must be in internal memory in order to be processed. thus, if located on secondary memory devices such as disks, programs and data are first loaded into internal memory. main storage and the cpu are connected to a console.
