What is a processor in OS?

 What is an Processor :

Processor is also called as brain of computer. "Processor" it means power to process and complete the given task in certain time is called processor. Processor is also known as “Microprocessor“, and it likes as small type of chip that is placed in the computers and another electronics components. Processor can manage all instructions such as arithmetical, logical, input/output (I/O) and other basic instructions, which are created by hardware or operating system.

Processors are used in PCs as well as they can be used into other electronic devices such as smart phones, tablets, PDA, and more. Intel and AMD are main companies, which are produced best quality processors in the market.

Components of Processor

There are four components to a computer processor: the ALU, FPU, registers, and cache memory.

• ALU stands for arithmetic logic unit, which help out to execute all arithmetic and logic operations.
• FPU Floating Point Unit is also called the “Math coprocessor” that helps to manipulate mathematically calculations.
• Registers store all instructions and data, and it fires operands to ALU and save the output of all operations.
• Cache memory helps to save more time in travelling data from main memory.

Types of Processor

There are 5 types of Processor

Single Core Processor:

Those CPUs were able to perform one operation at once, so they were not comfortable to multi tasking system. These CPUs got degrade the entire performance of computer system while running multiple programs at same time duration.

Dual Core Processor:

Dual Core processor contains two processors, and they are linked with each other like as single Integrated circuit. Every processor consist its own local cache and controller, so they are able to perform different difficult operations in quickly than single core CPU.

Multi Core Processor:

Multi core processor is designed with using of various processing units means “Cores” on one chip, and every core of processor is able to perform their all tasks. For example, if you are doing multiple activities at a same time like as using WhatsApp and playing games then one core handles WhatsApp activities and other core manage to another works such as game.

Quad Core Processor:

Quad core processor is high power CPU, in which four different processors cores are combined into one processor. Every processor is capable to execute and process all instructions own level without taking support to other left processor cores.

Octa Core Processor:

Octa core processor is designed with using of multiprocessor architecture, and its design produces the higher processing speed. Octa core processor has best ability to perform multi tasking and to boost up efficiency of your CPU.
