General news

A professor from Georgia Tech said that the usage of Graphene instead of silicon in the processor structure is better because:
The speed of the processor will be increased.
The temperature will be increased with small percentage because the graphene is good conductor and lose the heat quickly.

Disadvantage of graphene:-
Graphene isn't semiconductor(the scientists approach a solution solve this problem)

Processor overview

Processor(CPU):-
--------------
The CPU is the brain of the computer.
It executes the instructions of the computer programs.
It consists of two parts:
1- Control Unit.
2- Arithmetic/Logic unit(ALU).

Notes:-
-----
- Processor Number:
  It's the number that used to differentiate between 
  features of processors within a processor family.
  It doesn't measure the performance.

- Architecture:
  The structure of the transistors of the processors.

- Chipset:
  It's the chip that is soldered onto the motherboard
  and manages communication between memory, CPU, AGP,
  and I/O controller Hub(ICH).

- Clock speed:
  Indicates how many times per second a processor
  performs its most basic tasks.
  It is measured by MHz or GHz.

- Front Side Bus Speed:
  The speed of the bus that connects the processor
  and the main memory(RAM).

- L2 Cache:
  The size of second level cache.
  L2 cache is a fast memory that saves temporarily
  information.

- L3 Cache:
  The size of 3rd level cache.
  L3 cache is a fast memory that saves temporarily
  information.

- Memory type:
  Memory = main memory = RAM(Random Access Memory).
  It stores temporarily data.

- Number of pins:
  The backside of the processor has pins.

- Socket type:
  The socket is soldered onto the motherboard.
  This socket supports certain types of processors.

    It has the capability to scan business cards.

Note:-
-----
- Resolution:
  ----------
  Are the finest details between which a scanner can see.
  The scanner needs to be able to resolve the difference between very close together
  image elements.
