Hardware:
Motherboard:
The motherboard is a sheet of plastic onto which metallic circuits are printed (motherboard’s buses). It contains a series of slots for other components (the processor, the memory, key board control, etc...), and these smaller circuit boards will add to the motherboard capabilities. The motherboard is the most important part of the PC; it determines the internal computer architecture and ties it all together by sending power, data and instructions among all computer components.
CPU:
It is the Central Processing Unit of the computer and it is the part of a computer (a microprocessor chip) that does most of the data processing; “the CPU and the memory, form the central...
