Processors

WHAT IS IT ?

  • A processor is a chip handles all instructions it receives from hardware and software running on the computer.

  • It makes all the logical decisions which are basically all the tasks your computer does.

  • The processor is known as the brain of the computer

  • The first microprocessor was the Intel 4004.

  • We have a processor, RAM/ROM, and input coming from the output devices like Hard drive, mouse, keyboard, and monitor.

  • The mode of communication is called Motherboard.

  • It is responsible for linking the processor to all the component of your computer.

  • The processor executes 3 basic functions.

  • Receive input data

  • Process this data

  • Provide output data

Every processor contains several important features. Here are the main ones.

  • Socket: It is a type of physical connection between the processor and the motherboard. It is responsible for transmitting energy to the processor.

  • Core: Responsible for the processing speed. The more cores a processor has the more functions it can execute simultaneously without overloading your system.

  • Clock: Responsible for defining the frequency that a processor will use to execute one task. Means the amount of cycles that can happen in a given amount of time.

eg.

A processor has 2GHz clock frequency.

2 GHz

2000000000 cycle per second.

The higher the clock cycle is the lower the execution time will be, means a faster processor.

  • Cache: the Auxiliary memory of a processor where the most accessed data that will be processed is identified and then stored. The processor accesses this memory and is able to execute the action faster because it is more readily available.
