A motherboard provides the electrical connections by which the other components of the system communicate.
The Central Processing Unit (CPU; sometimes just called processor) is a machine that can execute computer programs.
Random access memory (RAM) is fast-access memory that is cleared when the computer is power-down. RAM attaches directly to the motherboard, and is used to store programs that are currently running. RAM is a set of integrated circuits that allow the stored data to be accessed in any order (why it is called random).
Firmware is loaded from the Read only memory (ROM) run from the Basic Input-Output System (BIOS).
The power supply converts about 100-120 volts of AC power to low-voltage DC power for the internal components to use.
Removable Media
DVD
Blue-Ray
CD
CDs are the most common type of removable media.
DVDs (digital versatile discs) are another popular optical disc storage media format. The main uses for DVDs are video and data storage.
Blu-ray is a newer optical disc storage media format. Its main uses are high-definition video and data storage.
A floppy disk is a type of data storage that is composed of a disk of thin, flexible(“floppy”) magnetic storage medium encased in a square or rectangular plastic shell.
A disk array controller is a device which manage the physical disk drives and presents them to the computer as logical units
A hard disk drive (HDD) is a non-volatile storage device which stores digitally encoded data on rapidly rotating platters with magnetic surfaces.
A solid-state drive (SSD) is a data storage device that uses solid-state memory to store persistent data. An SSD emulates a hard disk drive, thus easily replacing it in any application.
