Internal Computer Hardware
Motherboard
The motherboard is the body or mainframe of the computer, through which all other components interface.
Central Processing Unit:
is a machine that can execute computer programs. It is sometimes referred to as the brain of the computer.
Random Access Memory
RAM is a set of integrated circuits that allow the stored data to be accessed in any order (why it is called random).
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.But it is also tightly linked to a piece of hardware.
Power Supply
The power supply as its name might suggest is the device that supplies power to all the components in the computer. Its case holds a transformer, voltage control, and (usually) a cooling fan.
Removable Media Devices
CD, DVD or Blu-Ray
CD
There are two types of devices in a computer that use CDs: CD-ROM drive and a CD writer. The CD-ROM drive used for reading a CD. The CD writer drive can read and write a CD. CD writers are much more popular are new computers than a CD-ROM drive. Both kinds of CD drives are called optical disc drives because the use a laser light or electromagnetic waves to read or write data to or from a CD.
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. The disc has the same dimensions as a CD or DVD.
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. An SSD emulates a hard disk drive, thus easily replacing it in any application.
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. It almost always implements hardware RAID. RAID (Redundant Array of Independent Drives) is a technology that employs the simultaneous use of two or more hard disk drives to achieve greater levels of performance, reliability, and/or larger data volume sizes. A disk array controller also provides additional disk cache.
Internal storage is hardware that keeps data inside the computer for later use and remains persistent even when the computer has no power.
Floppy Disk
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, Many new computers do not come with floppy drives anymore but there are a lot of older ones with floppy drives lying around.
