How to install and remove a SATA hard drive How to remove and install a computer Power Supply Unit (PSU) How to install and remove computer Central Processing Unit (CPU) How to install and remove computer RAM **Keywords** **Hard disk drive (HDD)** or **Hard drive** **(HD)**: The primary computer storage device, which spins, reads and writes one or more fixed disk platters. @http://www.pcmag.com/encyclopedia/term/44088/hard-drive

**Solid state drive (SSD)**: A data storage device that uses integrated circuits as memory to store data persistently. SSDs use technology and interfaces compatible with traditional hard disk drives, but have no moving mechanical components. They are less susceptible to physical shock, quieter, and quicker, but are still substantially more expensive per unit of storage than traditional hard drives. @http://en.wikipedia.org/wiki/Solid_state_drive

**Optical disk drive**: A disk drive that uses laser light or electromagnetic waves within or near the visible light spectrum to read data from and write data to optical discs. Some drives can only read from the discs; others, often called **burners**, can write to discs as well (and are now commonplace). Types of optical disk drive include **CD-ROM/RW drives** (which read and/or write compact discs, or CDs), **DVD-ROM/RW drives** (which read and/or write DVDs), and **Blu-ray drives** (which read and/or write Blu-ray discs). Optical discs can store relatively large quantities of data, including music and videos, hence their use by the entertainment industry; however, they are less suited for the purposes of backing up large hard disk drives. @https://en.wikipedia.org/wiki/Optical_disc_drive

**Floppy disk drive (FDD)**: A disk drive that can read and write to **floppy disks**. Various sizes have existed -- including 8 inch, 5 1/4 inch, and 3 1/2 inch -- but floppy disks have been superseded by hard drives, rewriteable CDs and DVDs, USB thumb drives, and the use of networking hardware. @http://en.wikipedia.org/wiki/Floppy_disk

**Fragmentation**: Refers to the condition of a disk or of RAM in which files are divided into pieces scattered around the disk or broken up in memory. Fragmentation occurs naturally when you use a disk to frequently create, delete, and modify files. Utilities exist, both built-in to many operating systems and by third parties, to //defragment// disks and files, but are less necessary for some newer operating systems that use techniques to reduce fragmentation or automatically defragment in the background. @http://www.webopedia.com/TERM/F/fragmentation.html @http://lifehacker.com/5976424/what-is-defragging-and-do-i-need-to-do-it-to-my-computer @http://en.wikipedia.org/wiki/Fragmentation_(computing)

**Internal fragmentation**: Occurs when you allocate storage in memory or on a drive without ever intending to use it. This space is wasted. @http://en.wikipedia.org/wiki/Fragmentation_(computing)

**External Fragmentation**: Occurs when free storage on a drive becomes divided into many small pieces over time. @http://en.wikipedia.org/wiki/Fragmentation_(computing)

**Data fragmentation**: Occurs when a piece of data in memory or on a drive is broken up into many pieces that are not close together (or far apart). It is typically the result of attempting to insert a large object into storage that has already suffered external fragmentation. @http://en.wikipedia.org/wiki/Fragmentation_(computing)

**Thermal grease**: A fluid substance, originally with properties akin to grease, which increases the thermal conductivity of a thermal interface by compensating for the irregular surfaces of the components. Thermal grease is used between a chip (e.g. a CPU) and its heat sink. @http://en.wikipedia.org/wiki/Thermal_grease

**Heat sink**: An environment or object that absorbs and dissipates heat into the air from another object. In computers, heat sinks are used to cool CPUs or graphics processors. @http://en.wikipedia.org/wiki/Heat_sink

**Cooling**: Computer cooling is the process of removing heat from computer components. @http://computer.wikia.com/wiki/CPU_cooling

**Motherboard**: The central printed circuit board (PCB) found in complex electronic systems, such as modern personal computers. It holds many of the crucial electronic components of the system, including the CPU and RAM, and provides connectors for other peripherals. The motherboard is sometimes alternatively known as the mainboard, system board, or logic board. @http://en.wikipedia.org/wiki/Motherboard
