Input/output. v. t. e. In computing, a device driver is a computer program that operates or controls a particular type of device that is attached to a computer or automaton. [1] A driver provides a software interface to hardware devices, enabling operating systems and other computer programs to access hardware functions without needing to know ...
Yes. In computing, Serial Attached SCSI ( SAS) is a point-to-point serial protocol that moves data to and from computer-storage devices such as hard disk drives and tape drives. SAS replaces the older Parallel SCSI (Parallel Small Computer System Interface, usually pronounced "scuzzy" or "sexy" [3] [4]) bus technology that first appeared in the ...
June 1986 (X3.131-1986) Produced. Since 1983. Small Computer System Interface ( SCSI, / ˈskʌzi / SKUZ-ee) [2] is a set of standards for physically connecting and transferring data between computers and peripheral devices, best known for its use with storage devices such as hard disk drives. SCSI was introduced in the 1980s and has seen ...
Hard disk drive interface. Hard disk drives are accessed over one of a number of bus types, including parallel ATA (PATA, also called IDE or EIDE; described before the introduction of SATA as ATA), Serial ATA (SATA), SCSI, Serial Attached SCSI (SAS), and Fibre Channel. Bridge circuitry is sometimes used to connect hard disk drives to buses with ...
SCSI makes use of cables to connect devices. In a typical example, a socket on a computer motherboard would have one end of a cable plugged into it, while the other end of the cable plugged into a disk drive or other device. Some cables have different types of connectors on them, and some cables can have as many as 16 connectors (allowing 16 ...
Parallel ATA. Parallel ATA ( PATA ), originally AT Attachment, also known as Integrated Drive Electronics ( IDE ), is a standard interface designed for IBM PC -compatible computers. It was first developed by Western Digital and Compaq in 1986 for compatible hard drives and CD or DVD drives. The connection is used for storage devices such as ...
History Two SATA Express connectors (light gray) on a computer motherboard; to the right of them are common SATA connectors (dark gray). The Serial ATA interface was designed primarily for interfacing with hard disk drives (HDDs), doubling its native speed with each major revision: maximum SATA transfer speeds went from 1.5 Gbit/s in SATA 1.0 (standardized in 2003), through 3 Gbit/s in SATA 2. ...
t. e. In computing, an optical disc drive is a disc drive that uses laser light or electromagnetic waves within or near the visible light spectrum as part of the process of reading or writing data to or from optical discs. Some drives can only read from certain discs, but recent drives can both read and record, also called burners or writers ...
