Among other things, its configuration determines whether

8、 a computer is fast or slow in relation to other computers. The CPU is the most complex computer system component, responsible for directing most of the computer system activities based on the instructions provided. As one computer generation has evolved to the next, the physical size of the CPU has

9、 often become smaller and smaller, while its speed and capacity have increased tremendously. Indeed, these changes have resulted in microcomputers that are small enough to fit on your desk or your lap.The CPU comprises the control unit and the arithmetic / logic unit (ALU). The control unit is respo

10、nsible for directing and coordinating most of the computer systems activities. It determines the movement of electronic signals between main memory and the arithmetic/logic unit, as well as the control signals between the CPU and input/output devices.The ALU performs all the arithmetic and logical (

11、comparison) functions - that is, it adds, subtracts, multiplies, divides, and does comparisons. These comparisons, which are basically less than, greater than, and equal to, can be combined into several common expressions, such as greater than or equal to. The objective of most instructions that use

12、 comparisons is to determine which instruction should be executed next. Question：1. With the development of computer, the physical size of the CPU has often become bigger and bigger. ( F ) 2. The movement of electronic signals between main memory and the ALU as well as the control signal between the

13、 CPU and input /output devices are controlled by the control unit of the CPU. ( T )3. The CPU comprises the control unit and memory. ( F )4.
