  THE CENTRAL PROCESSING UNIT (CPU) DEFINITION, COMPONENTS OF CPU- CONTROL UNIT (CU), ARITHMETIC AND LOGIC UNIT (ALU), REGISTERS AND  FUNCTIONS DEFINITION OF THE CPU The Central Processing Unit (CPU) also known as the microchip or the microprocessor (or processor for short) is the electronic circuitry within a computer that carries out the instructions of a computer program. This is the brain or heart of the computer. The main objective of the CPU is to perform mathematical calculations on binary numbers. Most modern CPUs are microprocessors, meaning they are contained on a single integrated circuit (IC) chip. Some computers employ a multi-core processor, which is a single chip containing two or more CPUs called "cores". COMPONENTS OF CPU The major components of the CPU are: 1. Control Units (CU) 2. Arithmetic Logic Unit (ALU) 3. Registers. 4. Cache. 5. Clock. 1.  Control Unit (CU) : This  handles all processor control signals. It directs all input and output fl...
