Some says that processor are the brain of the computers because without it, basically it can’t function.
While others say that it is a chip that responds to and process the basic instructions that drive a computer.
Some even called it CPU which is Central Processing Unit.
To me it is an important chip that will interpret most of the computer commands.
Not only that it, communicates with other input/output device and memory & storage devices.
There is two parts in the processor which is Control Unit (CU) and Arithmetic Logic Unit (ALU).
CU is managed commands and perform accordingly and ALU performs mathematic calculation.
Some chips have high/small speed of registers that temporarily stores data such as address, command & results.
Temporarily store data are known as cache memory where it retrieves data from a computer’s memory more efficiently.
The 4 main functions of a processor are
Processor in a personal computer or maybe embedded in small devices are commonly called microprocessor.
Basically the microprocessor does all the four functions that I mentioned above.
These days, most computers will operate using a multi-core processor which means it a single chip than contains more than one CPU.
This means it will perform better, reduced power consumptions and process multiple task efficiently.
Most common computers may have up to four cores.
Basically single set of instruction that can process at one time is called single-core processor.
A CPU that process two sets of instructions at a time called dual-core and four sets of instructions at one time is called quad-core processor.
With more cores = more instructions at one time a computer can handle.
As years goes by and technology improved, hyper-threading was introduced and it increase the performance of the CPU Cores.
What it does is that one core with two hyper-threads can do two sets of instructions at one time.
This enables multiple threads to be run by each core to make the CPU run more efficiently.
With this explanation, it becomes more contradicting.
Does it mean more hyper-threading means its doubles the physical cores?
Nope it does not double the physical cores but it virtually doubles the amount of course that is in CPU.
The Operating System (OS) will still recognise the physical cores and the virtual/logical cores in the CPU.
The OS will schedule or share the workload between them.
It is just to virtually increase the sets of instructions in the pipeline to make the computer run more efficiently.
Have you ever thought like what is the maximum amount of cores that have been created?
I did saw one of the YouTube videos that AMD created a chip that is 64 cores with 128 threading.
When you pinned your CPU to your motherboard, you will need to apply a thermal paste on the chip,
attached the chip with a heat sink and a fan to dissipate heat.
Basically CPU produce more heats over period of time and CPU only function well below a certain temperate threshold.
With a cooling system, it keeps the CPU cooler and prevents from overheating.
Overheating a CPU could lead to fire and that is something that we do not want ii to happen.
