What are computer processing devices?

Computer processing devices play an important role in processing operations. They are all used in processing the data, using the program instructions. They manipulate the functions; they perform different calculations and also control the hardware devices. Computer processing devices are:

  • CPU
  • Motherboard
  • Chipset
  • Clock
  • Expansion slots
  • Data bus
  • Address bus
  • Control bus
  • RAM

Central Processing Unit:

The central processing unit is the main and the most important processing device of the computer system. It is also called the brain of the computer because it carries out the instructions of a computer program, and also all the functions of a computer. Without CPU computer is nothing. A computer cannot perform any of the operations for which it is intended without CPU.

Motherboard:

The motherboard is a circuit board. It is inside the computer that houses the CPU, memory, buses and all other components. It provides a communication way for all the components in a computer to communicate with each other.

Chipset:

A group of integrated circuits that work together and maintain and control the entire computer system is called Chipset. The flow of data throughout the system is handled by the chipset.

 

Clock:

The clock inside the computer is used to synchronize all the calculations of the computer. It ensures that all the circuits inside the computer are working together at the same time.

Expansion slots:

An expansion slot is a socket located on the motherboard. It is used to insert an expansion card, also called a circuit board which provides extra features to a computer like a video, sound, or memory, etc.

Data bus:

The data bus is located on the motherboard. It is a collection of wires which are used by the CPU to transfer data between all the components of the computer system. The data bus is bidirectional. Data flows from microprocessors to memory and input/output devices. And then data also flows from memory and input/output devices to the microprocessor.

Address bus:

The address bus is a collection of conducting wires which carry addresses only. The address bus is unidirectional. The data flows from a microprocessor to memory or from the microprocessor to input/output devices.

Control bus:

The control bus carries the signals that report the status of various devices. Normally the control bus is unidirectional but in case of a data bus, it has to be bidirectional.

RAM:

The RAM (Random Access Memory) is a temporary storage device for data in the computer system. It holds the data for a small period of time and temporarily only when the data is being processed.
