|| || (CD-ROM) || -is a pre-pressed compact disc that contains data accessible to, but not writable by, a computer for data storage and music playback. CD-ROMs are popularly used to distribute computer software, including games and multimedia applications, though any form of binary data can be stored (up to the capacity limit of a disc). || || || || || || || || || || || || || || || || || ||  || Back to Home
 * Backup || -is a computer program used to perform a complete backup of a file, data, database, system or server. The backup software enables a user to make an exact duplicate of everything contained on the original source. This software must also be used to perform a recovery of the data or system in the event of a disaster.
 * Bit || -is the basic unit of information in computing and telecommunications; it is the amount of information that can be stored by a digital device or other physical system that can usually exist in only two distinct states. In computing, a bit can also be defined as a variable or computed quantity that can have only two possible values. These two values are often interpreted as binary digits and are usually denoted by the Arabic numerical digits 0 and 1. The two values can also be interpreted as logical values (//true/////false//, //yes/////no//), algebraic signs (//+/////−//), activation states (//on/////off//), or any other two-valued attribute. In several popular programming languages, numeric 0 is equivalent (or convertible) to logical //false//, and 1 to //true//. ||
 * Byte || -is a unit of digital information in computing and telecommunications, that most commonly consists of eight bits. Historically, a byte was the number of bits used to encode a single character of text in a computer and it is for this reason the basic addressable element in many computer architectures.
 * Boot Sector || -is a sector of a hard disk, floppy disk, or similar data storage device that contains code for booting programs (usually, but not necessarily, operating systems) stored in other parts of the disk. ||
 * Compact Disk Read-Only Memory
 * Digital Video Disc (DVD) || -is an optical disc storage media format. Its main uses are video and data storage. DVDs are of the same dimensions as compact discs (CDs), but are capable of storing almost seven times as much data.
 * Failover || -is the capability to switch over automatically to a redundant or standby computer server, system, or network upon the failure or abnormal termination of the previously active application, server, system, or network. Failover happens without human intervention and generally without warning, unlike switchover.
 * Flash Memory || - is a non-volatile computer storage chip that can be electrically erased and reprogrammed.
 * Gigabyte (GB) || -is a multiple of the unit byte for digital information storage. The prefix //giga// means 109 in the International System of Units (SI), therefore 1 //gigabyte// is 1 000000000bytes . The unit symbol for the gigabyte is GB or Gbyte, but not //Gb// (lower case //b//) which is typically used for the gigabit.
 * Hard Disk Drive (HDD) || -is a non-volatile, random access device for digital data. It features rotating rigid platters on a motor-driven spindle within a protective enclosure. Data is magnetically read and written on the platter by read/write heads that float on a film of air above the platters.
 * Kilobyte (kB) || -is a multiple of the unit byte for digital information. The prefix //kilo// means 1000 in the International System of Units (SI), therefore 1 kilobyte is 1000 bytes . The recommended unit symbol for the kilobyte is kB or kbyte.
 * Megabyte (MB) || -is a multiple of the unit byte for digital information storage or transmission with two different values depending on context: 1 048576 bytes (220) generally for computer memory; and one million bytes (106, see prefix mega-) generally for computer storage. The IEEE Standards Board has decided that "Mega will mean 1 000 000", with exceptions allowed for the base-two meaning. In rare cases, it is used to mean 1000×1024 ( 1 024000  ) bytes. It is commonly abbreviated as Mbyte or MB (compare Mb, for the megabit).
 * Memory Card || -is an electronic flash memory data storage device used for storing digital information. They are commonly used in many electronic devices, including digital cameras, mobile phones, laptop computers, MP3 players, and video game consoles. They are small, re-recordable, and they can retain data without power.
 * Mirroring || -is an exact copy of a data set. On the Internet, a mirror site is an exact copy of another Internet site. Mirror sites are most commonly used to provide multiple sources of the same information, and are of particular value as a way of providing reliable access to large downloads. Mirroring is a type of file synchronization.
 * Non-Volatile Memory || -is computer memory that can retain the stored information even when not powered and is typically used for the task of secondary storage. ||
 * Petabyte (PB) || -is a unit of information equal to one quadrillion (short scale) bytes, or 1000 terabytes. The unit symbol for the petabyte is PB. The prefix peta- (P) indicates a power of 1000. When used for computer memory the petabyte can also used for the corresponding power of 1024
 * Primary Storage || -is the only one directly accessible to the CPU. The CPU continuously reads instructions stored there and executes them as required. Any data actively operated on is also stored there in uniform manner.
 * Random Access Memory (RAM) || -is a form of computer data storage and takes the form of integrated circuits that allow stored data to be accessed in any order (i.e., at random). "Random" refers to the idea that any piece of data can be returned in a constant time, regardless of its physical location and whether it is related to the previous piece of data.
 * Redundancy || -is the duplication of critical components of a system with the intention of increasing reliability of the system, usually in the case of a backup or fail-safe.
 * Secondary Storage || -differs from primary storage in that it is not directly accessible by the CPU. The computer usually uses its input/output channels to access secondary storage and transfers the desired data using intermediate area in primary storage. Secondary storage does not lose the data when the device is powered down—it is non-volatile.
 * Storage || -refers to computer components and recording media that retain digital data used for computing for some interval of time. Computer data storage provides one of the core functions of the modern computer, that of information retention. It is one of the fundamental components of all modern computers, and coupled with a central processing unit (CPU, a processor), implements the basic computer model used since the 1940s.
 * Terabyte (TB) || -is a multiple of the unit byte for digital information. The prefix //tera// means 1012 in the International System of Units (SI), and therefore 1 terabyte is 1 000000000000bytes, or 1 trillion (short scale) bytes, or 1000 gigabytes. 1 terabyte in binary prefixes is 0.9095 tebibytes, or 931.32 gibibytes. The unit symbol for the terabyte is TB or Tbyte.
 * USB Flash Drive || -consists of a flash memory data storage device integrated with a USB (Universal Serial Bus) interface. USB flash drives are typically removable and rewritable, and physically much smaller than a floppy disk. Most weigh less than 30 g (1 oz). Storage capacities in 2010 can be as large as 256 GB with steady improvements in size and price per capacity expected. Some allow 1 million write or erase cycles and have a 10-year data retention cycle.
 * User Account || -allows a user to authenticate to system services and be granted authorization to access them.
 * Volatile Memory || -is computer memory that requires power to maintain the stored information and has been less popularly known as temporary memory. ||
