THE PROCESSOR


The function of the processor

The processor is a chip that controls all the
computer instructions by interpreting them as 
a binary code. 
The control circuitry pulls data in via the various ports, directs it along data buses,stores it in the memories and performs the calculations

Its roles

Performing calculations: the calculations are made by components in the cpu using binary code.
Data manipulation: The cpu can receive data from input devices, store the instructions and send data back to output devices
Decision making

Performance features

Clock speed: Is the speed at which the microprocessor executes instructions
 Cores:It is the processing unit.  For example, having two cores, multiply the processing power of the cpu by two. 
 Cache Is a small and fast memory, situated close to the cpu to accelerate the processor performance by storing copies of the most frequently used datas

Makes

Intel and AMD are the most famous and the best cpu brands, that have a lot of options and support, as a big community too. 
 ARM Is the builder of smartphone processors

Overclocking

Overclocking or Underclocking are processes that an owner can do to improve the computer functions.
Overclocking increase the voltage, hence having more processing power, instead, Underclocking reduce the voltage, therefore having more battery time.


Heat sinks – purpose, water cooled, air cooled

Image result for heat sink
As the processor is running a lot of instructions, it tends to heat up, therefore computers have different ways to dissipate the heat. A regular pc use a metal heat sink for this purpose alongside with fans.
 Another type of heat sink use sealed tubes with water to dissipate the heat from the processor, it uses the same principle as a car radiator. The water cooled system alows the computers to be thinner.

MEMORY A memory is a temporary storage that computers uses to hold data and instructions. One of the most important storage devices is random access memory(RAM), that is  the  fastest way in which data can get to the processor.  Random access memory (RAM) is the temporary storage for data and programs that are being  accessed by the CPU. Non volatile / volatile A volatile memory, lose its data when the computer is  powered off. On  the other hand,  a Non Volatile memory that does not lose its data when switched off. Different types: RAM :  Is one of the most important storage devices,  is a volatile memory, that stores data and programs that are being accessed by the CPU. RAM is a volatile memory. ROM: Read-only memory (ROM)  contains basic instructions for booting the computer and loading the operating system.  ROM, on  the other hand,  is a Non Volatile memory CACHE: Is fast and expensive as well. It is located inside the proces

SPECIALIZED CARDS These cards increase the functionality of your computer and allow it to do specific tasks. Each card can do different chores. Now a days, most computers have on board chips that substitute the cards functions. Sound card: It manages input and output signals and then produce sound for the headphones or speakers. you can connect multiple sound devices and it can play mp3 files. Graphic Card : The function of this card is to generate output images to display through screens. Graphic cards work with more advanced programs such as Adobe's package. It can playback other recreational software such as videos, games... this card can have different ports: VGA, dvi, Svideo... Network Card : It allows the computer to connect to different networks, to another computer and you can create small networks as well, it has an Ethernet Socket, RJ45.
