 What is the Central Processing Unit (CPU) mean?

 The central processing unit (CPU) is the unit that processes the computer most.  In other parts of the computer, the CPU relies heavily on a chipset, which is a group of microchips located on the motherboard.


 There are two CPU components:

  1. Control unit: Removes directives from the memory and decodes and executes them
  2. Arithmetic logic unit (ALU): handles arithmetic and logical operations

 To work properly, the CPU system relies on the clock, memory, secondary storage and data, and address buses.

 This term is also known as a central processor, microprocessor or chip.

 Interprets central processing unit (CPU)


 The CPU is the heart and brain of the computer.  It obtains data input, executes the instructions, and processes the information.  It communicates with input/output devices (I / O), which send and receive data from the CPU.  In addition, the CPU has an internal bus for communication with internal cache memory, called backside bus.  The main bus is called a front-side bus for data transfer from CPU, memory, chipset and AGP socket.

 The CPU contains internal memory units, which are called registers.  These registers include data, instructions, counters, and addresses used in information processing of ALU.

 Some computers use two or more processors.  There are different physical CPUs on the same board or on different boards.  Each CPU has an independent interface, different caches and different ways for system front-side bus.  Many processors are ideal for integrated parallel functions requiring multitasking.  Multicore CPUs are also common, with a single chip having many CPUs
