`
`rapid application
`RAD Acronym for
`development. In object—oriented program—
`ming, a method of program development
`in which a programmer works with a
`library of prebuilt objects, allowing him to
`build programs much more quickly.
`
`radio button In a graphical user inter—
`face (GUI), the round option buttons that
`appear in dialog boxes. Unlike check boxes,
`radio buttons are mutually exclusive; the
`user can pick only one radio button option
`within a group.
`
`radio frequency interference (RFI)
`The radio noise generated by computers
`and other electronic and electromechanical
`
`devices. Excessive RFI generated by com—
`puters can disrupt the reception of radio
`and television signals. See FCC certification.
`
`RAID Acronym for Redundant Array of
`Inexpensive Disks or Redundant Array of
`Independent Disks. A group of hard disks
`under the control of array—management
`software that work together to improve
`performance and decrease the odds of los—
`ing data due to mechanical or electronic
`failure by using such techniques as data
`striping. Because of their complexity and
`cost, RAID implementations are most
`often used on network servers. Several
`
`RAID levels exist, each with advantages
`and disadvantages. RAID arrays are gener—
`ally used for high—volume servers. See
`RAID 0, RAID 1, RAID 2, RAID 5,
`RAID 10.
`
`RAID 0 A type of RAID storage device
`that combines two or more hard disks into
`
`a single logical drive.The technique used is
`called disk striping; data is written in blocks
`to each drive in a sequence, producing very
`
`fast performance. However, RAID 0
`devices do not provide data redundancy
`and are therefore unsuitable for applica—
`tions involving mission—critical data. See
`RAID.
`
`RAID 1 A type of RAID storage device
`that combines two or more hard disks into
`
`a single logical drive, but—in contrast to
`RAID O—in a way that backs up the data
`so that nothing is lost if one of the drives
`should fail. Performance is sacrificed for the
`
`sake of data integrity. See RAID.
`
`RAID 2 A type of RAID storage device
`that combines two or more hard disks into
`
`a single logical drive. Like RAID 0, RAID
`2 provides fast performance but does not
`provide data protection in case of a drive
`failure. However, it does provide a means of
`verifying whether write operations were
`performed correctly, so it
`is suitable for
`backup operations. See RAID.
`
`RAID 5 A type of RAID storage device
`that combines three or more hard disks
`
`into a single logical drive. Like RAID 0.
`RAID 5 provides high write speed, but the
`striping technique used creates sufficient
`redundant information that all the data can
`be reconstructed if one of the drives should
`fail. See RAID.
`
`RAID 10 Also known as RAID 1 + (I.
`
`A type of RAID storage device that com-
`bines the benefits of RAID 0 (high speed
`with RAID 1
`(data integrity). Although
`this approach requires twice as many drives
`as any of the other RAID standards,
`it
`ofers the best combination of performance
`and data integrity. See RAID.
`
`RAM See random access memory (RAM).
