What is the computer processor?
A processor is a hardware device which calculates a large number of calculation and give their result to the user, in the other word a process is an electronic device which responds when we give them instruction, this processor is looks like a chip.
The processor of the computer is also called CPU (Central processing unit), because this on one of the most important parts of the complete CPU, we cannot imagine the computer without the CPU, because in the absence of CPU computers is not able to give responses to the user.
The processor in the mobile, tablets, and other small devices are called the microprocessor, this microprocessor is very small in size, in the computer processor is not only responsible for the process of instruction, there are other elements such as Hard drive are also responsible for the processing
But the Hard drives process very small instruction, most of the processing work is doing by the main processor due to the working of this microprocessor this is called the CPU of the device, this is also called the brain of the device, Intel and AMD are two main company which makes the processor of the computer and microprocessor of the mobile.
Elements of the Processor/Microprocessor
(a) Arithmetical and logical unit (ALU)
ALU is the part of the processor and the working procedure of the ALU are two types
Arithmetical unit:-Under this section ALU perform basic function like Addition, Subtraction, Multiplication, and Division.
Logical unit:-Logical unit of the processor is also performs some basic operations such as the comparison between two or more numbers such that the number is greater or less than another number.
(b) Floating point unit
The floating-point is also the part of the processor this unit also process the instruction but the speed of this unit is fast than ALU, the FPU of the processor performs the operation such as Addition, Subtraction, Multiplication, Division, Square root, Trigonometric values, exponential values and perform other operations.
(c) Control unit
The Control Unit of the processor/CPU is similar to the teacher in the class, just as teacher control in all the class during the teaching similarly Control unit of the processor control all the activities of the computer it, work as a supervisor, it fetches all the instruction from the RAM and control their execution.
(d) Resistor in the Processor
This is also the main part of the CPU, because when we fetch any instruction from the memory and execute this instruction then this resistor holds the instruction.
Operation inside the Processor
There are many types of operation are executed inside the processor, Due to this execution our work may be completed this operation is discuss in below.
Fetch:-It is a process where processor collects data from the memory and execute this data according to the given condition
Decode:-It is the operation of the processor where digital data converted into the plain text (Readable language) because inside the computer all the data stay in the form of the binary number so to make it readable we use decode processing.
Execute:-This is the last operation of the processor, at this state all the instruction come in the readable form and we can easily understand it, in this process all the given instruction be solved and give their final result.
What is the Core of the processor?
The core of the process is equal to the number of CPU inside the processor, from the above article we explain that the processor of the computer is a hardware chip and in this chip made by many components such as ALU, FPU, Control unit, resistor these four component is the main part of the processor and this four-component stay inside the process.
The combination of the above four components make a CPU and this single CPU is called a single-core processor and if we add a second CPU inside the processor then the processor is called a dual-core processor.
If we add four CPU inside the processor then it is called a quad-core processor and if we add eight CPU inside the processor then it is called the Octa-core processor.
