WHAT ARE COMPUTER PROCESSORS ? WHY THEY ARE THAT IMPORTANT IN A COMPUTER?

WHAT ARE COMPUTER PROCESSORS?

If you are a computer user this question may arise in your mind that how your computer works what makes it the most intelligent device on the planet and sometime what makes the pc hot.

The answer to all of this question is simple , its the processor which does all of this work . 

its only of about 2.5 inches but does work that most people cant do, Lets get deep into this.

first of all a computer is just a tin box until it has a processor in it . computer processor is the main brain of the computer . It can do calculations which normal people cant do normally.

Now the question that comes into the mind is that where this powerful instrument is found , it is found in the mother board. Basically motherboard is the thing which makes this chip functional and for graphic there is another processor which is called graphic processors , GPUs, or graphic card there are many names to this thing you can choose what you like among all the names. dedicated graphic card is needed where the processor alone can't make it possible to render graphics on the computer screen.

Most modern CPUs are microprocessors , where the CPU is contained on a single metal oxide semiconductor (MOS) integrated chip (IC) chip. An IC that contains a CPU may also contain memory , peripheral interfaces, and other components of a computer; such integrated devices are variously called microcontolers or system on a chip (SoC). Some computers employ a multi core processor , which is a single chip containing two or more CPUs called "cores"; in that context, one can speak of such single chips as "sockets".

The elements of a processor are:-

• The arithmetic logic unit (ALU), which carries out arithmetic and logic operations such as addition , subtraction , multiplication and divide on the operands in instruction. 
• The floating point unit (FPU), also known as a math coprocessor or numeric coprocessor, a specialized coprocessor that manipulates numbers more quickly than the basic microprocessor circuitry can.
• Registers, which hold instructions and other data. Registers supply operands to the ALU and store the results of operations.
• L1 and L2 cache memory . Their inclusion in the CPU saves time compared to having to get data from random access memory (RAM).

The two companies that are like by me and other reputed gamer are intel and amd.

Operations of CPU are :-

The four primary functions of a processor are fetch, decode, execute and write back.

• Fetch- is the operation which receives instructions from program memory from a systems RAM.
• Decode- is where the instruction is converted to understand which other parts of the CPU are needed to continue the operation. This is performed by the instruction decoder
• Execute- is where the operation is performed. Each part of the CPU that is needed is activated to carry out the instructions.

• Components and how a CPU works

  The main components of a CPU are the ALU, registers and control unit. The basic functions of the ALU and register are labeled in the above “basic elements of a processor section.” The control unit is what operates the fetching and execution of instructions.
  The processor in a personal computer or embedded in small devices is often called a microprocessor. That term means that the processor's elements are contained in a single IC chip. Some computers will operate using a multi core processor —a chip containing more than one CPU. A CPU is typically a small device with pins on it facing down in a motherboard . CPUs can also be attached to a motherboard with a heat sink and a fan to dissipate heat.
