What is Central Processing Unit ? endobj RAM Disk is used to provide extra memory for program data storage. The central processing unit (CPU) is the computer component that's responsible for interpreting and executing most of the commands from the computer's other hardware and software. 7 0 obj <> Through The major components of the CPU are an arithmetic and logic unit (ALU) and a control unit (CU). It controls the functioning of the other units and process the data. <> It constitutes the physical heart of the entire computer system; to it is linked various peripheral equipment, including input/output devices and auxiliary storage units. endobj The CPU is connected to the rest of the system through system bus. A central processing unit (CPU) is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions. It is the responsibility of the Control Unit to tell the computer’s memory, arithmetic/logic unit and input and output devices how to respond to the instructions that have been sent to the processor. The picture below is an example of what the top and bottom of an Intel Pentium processor may look. The central processing unit is the main component on a computer that determines how fast a system runs. endobj It is a multipurpose, programmable, clockdriven, register based electronic device - that accepts binary data as input, processes it according to instructions stored in its memory, and provides results as output. <> 2 0 obj A Central Processing Unit, or CPU has three main components, # The Arithmetic and Logic Unit, or ALU, which performs all of the calculations.
