2.It carries out arithmetic tasks, such as: +, - , *, / and logic operations, such as: >, >=, <, <=, = <>, AND, OR, NAND, NOR on the operands in computer instruction words.It organizes the whole computer, gets commands from the RAM and ROM, understands and acts on the commands, generate signals for the other parts of computer to perform different tasks, guides and controls the actions of the input and output devices.Components of a CPU

2. Central Processing Unit (CPU)
   Each computer has one processor at the minimum, which is called Central Processing Unit (CPU), brain or virtual brain of the computer. It accomplishes all kinds of tasks like information processing, storing, accessing, and instruction processing. It also controls all parts of the computer. CPU consists of Control Unit, Arithmetic and Logical Unit and Register. The CPU is composed of a very small and thin sheet of semiconductor material. It holds millions of small transistors and pathways those carry the information, instructions, perform calculations as per the given commands, and generates the output as per the given command. The components inside it are so small that you need a microscope to see them. Figure 1.12 shows the most common type of computer processor, Intel and AMD processors. Example (Intel Core i3, i5, i7 and i9).

Components of a CPU

• Control Unit (CU): controls and sequences all the processes performed by processor. It manages the flow of data through the components of the CPU. CU is considered as the central nervous system for all the internal parts. It organizes the whole computer, gets commands from the RAM and ROM, understands and acts on the commands, generate signals for the other parts of computer to perform different tasks, guides and controls the actions of the input and output devices.
• Arithmetical and Logical Unit (ALU): does the actual processing. It carries out arithmetic tasks, such as: +, - , *, / and logic operations, such as: >, >=,
