Internal Computer Hardware
Motherboard
A motherboard provides the electrical connections by which the other components of the system communicate.
Central Processing Unit
The Central Processing Unit (CPU; sometimes just called processor) is a machine that can execute computer programs. It is sometimes referred to as the brain of the computer.
Random Access Memory
Random access memory (RAM) is fast-access memory that is cleared when the computer is power-down.
Firmware
Firmware is loaded from the Read only memory (ROM) run from the Basic Input-Output System (BIOS). It is a computer program that is embedded in a hardware device, for example a microcontroller.
Power Supply
The power supply converts about 100-120 volts of AC power to low-voltage DC power for the internal components to use.
Removable Media
Putting something in your computer and taking it out is most likely a form of removable media. There are many different removable media devices.
CD
CDs are the most common type of removable media. They are inexpensive but also have short life-span. There are two types of devices in a computer that use CDs: CD-ROM drive and a CD writer.
DVD
DVDs (digital versatile discs) are another popular optical disc storage media format. The main uses for DVDs are video and data storage.
Blu-ray
Blu-ray is a newer optical disc storage media format. Its main uses are high-definition video and data storage.
Floppy Disk
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. Floppy disks are a dying and being replaced by the optical and flash drives.
Internal Storage
Hard Disk Drive
A hard disk drive (HDD) is a non-volatile storage device which stores digitally encoded data on rapidly rotating platters with magnetic surfaces.
Solid State Drive
A solid-state drive (SSD) is a data storage device that uses solid-state memory to store persistent data.
Disk Array Controller
A disk array controller is a device which manage the physical disk drives and presents them to the computer as logical units.
