| disk imaging software | Software used to copy sectors between devices. For example, you can use disk imaging software to copy an ISO image to a disk device sector-by-sector, preserving the image’s boot sector. An ISO image copied in this way can be used to start the system BIOS.
🗑

||||
| disk mirroring | A RAID configuration consisting of two identical hard disks to which identical data is written in parallel, thus ensuring fault tolerance. Also known as RAID 1.
🗑
|
||||
| disk striping | A RAID configuration in which a single file is divided into sections, which are then written to different hard disks concurrently to speed up access time; this type of RAID is not fault tolerant. Also known as RAID 0.
🗑
|
||||
| disk striping with parity | A RAID configuration that incorporates disk striping for faster file access, as well as parity information to ensure fault tolerance. Also known as RAID 5.
🗑
|
||||
| fault tolerant | Term used to describe a device that exhibits a minimum of downtime in the event of a failure.
🗑
|
||||
| File Transfer Protocol (FTP) | The most common protocol used to transfer files across the Internet.
🗑
|
||||
| firmware RAID | A RAID system controlled by the computer’s BIOS.
🗑
|
||||
| hardware RAID | A RAID system controlled by hardware located on a disk controller card within the computer.
🗑

||||
| Hypertext Transfer Protocol (HTTP) | The protocol used to transfer information over the Internet.
🗑
|
||||
| installation log files | The files created at installation to record actions that occurred or failed during the installation process.
🗑

||||
| Internet SCSI (iSCSI) | A SCSI technology that transfers data via TCP/IP networks.

|
||||
| iSCSI initiator | The software and hardware components that can be used to transfer files to and from an iSCSI target.
🗑
|
||||
| iSCSI target | An external iSCSI storage device that hosts one or more hard disks.

🗑
|
||||
| Logical Unit Number (LUN) | A unique identifier for each device attached to any given node in a SCSI chain.
🗑
|
||||
| Network File System (NFS) | A distributed filesystem developed by Sun Microsystems that allows computers of differing types to access files shared on the network.
🗑
|
||||
| Overclocked | Term used to describe a CPU that runs faster than the clock speed for which it has been rated.
🗑
|
||||
| Parallel SCSI | The traditional SCSI technology that transfers data across parallel cables.
🗑
|
||||
| Redundant Array of Independent Disks (RAID) | The process of combining the storage space of several hard disk drives into one larger, logical storage unit.
🗑
|
||||
| SCSI ID | A number that uniquely identifies and prioritizes devices attached to a SCSI controller.
🗑
|
||||
| segmentation fault | An error that software encounters when it cannot locate the information needed to complete its task.
🗑
|
||||
| Serial Attached SCSI (SAS) | A SCSI technology that transfers information in serial mode rather than the traditional parallel mode.
🗑
|
||||
| software RAID | A RAID system that is controlled by software running within the operating system.
🗑
|
||||
| Spanning | A type of RAID level 0 that allows two or more devices to be represented as a single large volume.
🗑
|
||||
| Storage Area Network (SAN) | A group of computers that access the same storage device across a fast network.
🗑
|
||||
| target ID | See also SCSI ID.
🗑
|
||||
| Terminator | A device used to terminate an electrical conduction medium to absorb the transmitted signal and prevent signal bounce.
