| 662 | What is inside a PC system? The nerve centre of a PC is _______, also called the CPU, or _______. This is built into a single chip, which executes program instructions and coordinates the activities that take place within the computer system. The chip itself is a small piece of silicon with a complex electrical circuit called _______. The processor consists of three main parts: _______examines the instructions in the user's program, interprets each instruction and causes the circuits and the rest of the components – monitor, _______, etc. – to execute the functions specified. _______ (ALU) performs _______ (+, -, etc.) and logical operations (AND, OR, NOT). _______are high-speed units of memory used to store and control _______. One of the registers (the program counter, or PC) keeps track of the next _______ to be performed in the main memory. The other (the instruction register, or IR) holds the instruction that is being executed. Put the phrases in the correct order to complete the text. One of the registers (the program counter, or PC) keeps track of the next _______ to be performed in the main memory. | Открыть |
| 663 | Read the passage. RAM and ROM The programs and data which pass through the processor must be loaded into the main memory. Therefore, when the user runs a program, the CPU looks for it on the hard disk and transfers a copy into the RAM chips. RAM (random access memory) is volatile – that is, its information is lost when the computer is turned off. However, ROM (read only memory) is non-volatile, containing instructions and routines for the basic operations of the CPU. The BIOS (basic input/output system) uses ROM to control communication with peripherals. RAM capacity can be expanded by adding extra chips, usually contained in small circuit boards called dual in-line memory modules (DIMMs). Identify if the statements below are TRUE/FALSE/NOT GIVEN The programs and data must be loaded into the main memory in order to be processed. | Открыть |
