What is Core in computer

 What is Core in computer ?

A Core is a small CPU or processor build into a big CPU or CPU socket.

A Core or CPU core is the brain of a CPU. It receives instruction and performs calculations or operations to satisfy those instruction .

A CPU can have multiple cores - 

1. Two cores - dual core processor

2. Four cores - quad core   ,,

3. Six cores -  hexa  core      ,,

4. Eight cores - octa core   ,,

CPU - Central Processing Unit - also known as processor,Central processor , or microprocessor.

Types of CPU:

In past, computer processors used numbers to identify the processor and help identify faster processor.

For example : Intel 80486(486) processor is faster than 80386(386) processor.

Today processor are different architecture 32 bit and 64 bit .

Component of CPU :

There are two primary component.

1. ALU ( Arithmetic Logic Unit ) 

2. CU ( Control Unit )

What is Core i3, i5 , i7 , i9 ?

Core i3 : core i3 is a dual - core computer processor, available for use in both desktop and laptop computers.

Core i5 :  core i5 is a computer processor, available as dual core or quad - core.

It can be used in both desktop and computers.

Core i7 :  they feature either four or six cores with stok frequency .

Core i9 :  core i9  CPU feature as few as six and many as eighteen cores , with threads.
