A drive that can hold either a 5 inch or 3 inch floppy disk. Also called floppy drive. | floppy disk drive (FDD) |
The top or bottom surface of one platter on a hard drive. Each platter has two heads. | head |
A number assigned to a logical device (such as a tray in a CD changer) that is part of a physical SCSI device, which is assigned a SCSI ID. | Logical Unit Number (LUN) |
A hard drive whose disk controller is integrated into the drive, eliminating the need for a controller cable and thus increasing speed, as well as reducing price. See also EIDE. | IDE (Integrated Drive Electronics or Integrated Device Electronics) |
An IDE cable that is narrower and has fewer pins than the parallel IDE 80-conductor cable. | serial ATA cable |
The circuit board that controls a SCSI bus supporting as many as seven or fifteen separate devices. The host adapter controls communication between the SCSI bus and the PC. | host adapter |
The resistor added at the end of a SCSI chain to dampen the voltage at the end of the chain. | terminating resistor |
A fast interface between a host adapter and the CPU that can daisy chain as many as 7 or 15 devices on a single bus. | SCSI (Small Computer System Interface) |
A feature of system BIOS and hard drives that automatically identifies and configures a new drive in BIOS setup. | autodetection |
The first sector of a floppy disk or hard drive volume; it contains information about the disk or volume. On a hard drive, if the boot record is in the active partition, then it can be used to boot the OS. Also called boot sector. | boot record |
The main secondary storage device of a PC. Two technologies are currently used by hard drives: magnetic and solid state. Also called a hard disk drive (HDD). | hard drive |
One or more sectors that constitute the smallest unit of space on a disk for storing data (also referred to as a file allocation unit). Files are written to a disk as groups of whole clusters. | cluster |
A SCSI standard that allows for more than 15 devices on a single SCSI chain, uses smaller, longer, round cables, and uses smaller hard drive form factors that can support larger capacities than earlier versions of SCSI. | serial attached SCSI (SAS) |
A male 9-pin or 25-pin port on a computer system used by slower I/O devices such as a mouse or modem. Data travels serially, one bit at a time, through the port. | serial port |
An older IDE cabling method that uses a 40-pin flat or round data cable or an 80- conductor cable and a 40-pin IDE connector. | parallel ATA (PATA) |
