28. Standard that specifies full SATA cabling for external disks.






29. Most often called a hard drive - comes in two sizes for personal computers: the 2.5" size is used for laptop computers and the 3.5" size is used for desktops. In addition - a smaller 1.8" size (about the size of a credit card) hard drive is used in s






30. A standard for managing the interface between secondary storage devices and a computer system. A system can support up to six serial ATA and parallel ATA IDE devices or up to four parallel ATA IDE devices such as hard drives - CD-ROM drives - and DVD






31. Operating system feature that enables a computer to assign itself an address if it is unable to contact a DHCP server. The Internet Assigned Numbers Authority (IANA) has reserved private IP addresses in the range of 169.254.0.0 -169.254.255.255 for A

33. A table on a hard drive or floppy disk that tracks how space on a disk is used to store files.






34. The duplication of everything written to a hard drive.






35. Having the ability to connect and disconnect a drive while the system is running. Also called hot-plugging.






36. Expansion card that increases the number of controllers and ports available on a computer.






37. A method of data transfer between hard drive and memory that allows multiple data transfers on a single software interrupt.






38. Formatting performed by means of the DOS or Windows Format program (for example - FORMAT C:/S creates the boot record - FAT - and root directory on drive C and makes the drive bootable). Also called OS formatting.






39. Issues dial - hang up - reset - and other instructions to the modem. It is based on the Hayes command set.
