The control unit (CU) is a component of a computer's central processing unit (CPU) that directs operation of the processor. The C P U is one the most important component that works as processing engine and the work horse for the computer system. The CPU is also called a processor or central processor. But it is not the only component, it represents the mind of the computer, whether it is a desktop computer, laptop, or mobile, and it is found in several home devices, especially those that deal with the Internet of things such as the Smart TV. As Figure 1 shows, the central processing unit consists of two parts: The control unit and the arithmetic/logic unit. Lecture B2 – Structure and Function of Central Processing Unit, Instruction Cycle. Get free quote and latest price from quality supplier, trader and distributor on HKTDC Sourcing. The central processing unit (CPU) of a computer is a piece of hardware that carries out the instructions of a computer program. The Central Processing Unit does the work of performing the computations given to the computer. The reason it is called a computer is because it does just that, it computes. It tells the computer's memory, arithmetic and logic unit and input and output devices how to respond to the instructions that have been sent to the processor. The central processing unit is the main component on a computer that determines how fast a system runs. Central processing unit (CPU) A component of a computer responsible for the basic functioning of the system; Also known as the brains of the computer To increase a CPU's speed a person can: System Unit is the hardware based aluminum chase, inside which all the electrical components and other computer processors reside and work. the CPU In a computer what covers the microprocessor?
