Processing Processing components are responsible for actually carrying out actions in the computer. A Central Processing Unit or the CPU has three main parts which are the Arithmetic Logic Unit (ALU), the control unit (CU), and the Memory Unit. All modern CPUs have control logic to attach the CPU to the rest of the computer. In modern computers, this is usually a bus controller. When an instruction reads or writes memory, the control unit either controls the bus directly, or controls a bus controller. Many modern computers use the same bus interface for memory, input and output. The ALU is responsible for performing all the arithmetic and bitwise operations . To store program instructions, 5. The CPU Is considered as the brain or heart of the computer as it is responsible for each and every operation performed in a computer system. Most of the signals can be generated from the instruction opcode alone, intervention. The Control unit will store the data values which are fetched from the main memory into the accumulator for the arithmetic or any other logical operations. Each of these components are pictured in the diagram below. The CPU is a Pentium III processor for mobile PCs. Input/Output Data Transfer.
