POWER SUPPLY

FUNCTION:

Image result for power supplyThis internal hardware component supplies electric power to the computer by transforming Alternating Current (AC) into Direct Current (DC) and decrease the voltage into three different outputs: 12v, 5v and 3.3v. 
Each voltage are dedicated to different elements of the computer

RATING:

The power is measured in Watts, higher the need; components such as hard drives and cards, higher the power needed. 

CONNECTOR TYPES

The most common is the Molex connector, although it's a bit old nowadays and we have more modern connections as SATA

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 CAC...
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 fre...
