Hard drive (hdd)

A hard disk drive (HDD) is a data storage device used for storing and retrieving digatal information using rapidly rotating disks coated with magnetic material. An HDD keeps its data even when powered off. Data is read in a random manner, meaning individual blocks of data can be stored or retrieved in any order rather than in order . An HDD consists of one or more hard rapidly rotating disks with magnetic heads arranged on a moving actuator arm to read and write data to the surfaces.

Mother board

A motherboard is the main printed curit board (PCB) found in computers. It holds many of the crucial electronic components of the system, such as the CPU and memory and provides connecters for other preipherals

power supply

a power supply unit converts mains ac into to low-voltage regulated DC power for the components of the internal computer. modern PCs universally use a switched mode power supply. Some power supplies have a manual selector for input voltage, while others automatically adapt to the supply voltage.

an optical disc drive is a disk drive that uses laser light or electromagnetic waves within or near the visable light spec as part of the process of reading or writing data to or from optical discs. Some drives can only read from discs, but recent drives are commonly both readers and recorders, also called burners or writers.dvds, and blue ray are common types of optical media which can be read and recorded by such drives


Random access memory (RAM) is the best known form of RAM is considered "random access" because you can access any memory cell directly if you know the row and column that intersect at that cell.The opposite of RAM is serial access memory (SAM). SAM stores data as a series of memory cells that can only be accessed sequentially like a cessect tape
