41 bus
A communication line used for data transfer among the components of a computer system. -
42 compatibility
"The degree to which a computer, an attached device, a data file, or a program can work with or understand the same commands, formats, or language as another. True compatibility means that any operational differences are invisible to people and programs alike." -
43 control
Management of a computer and its processing abilities so as to maintain order as tasks and activities are carried out. Control applies to measures designed to ensure error-free actions carried out at the right time and in the right order relative to other data-handling or hardware-based activities. -
44 directory
"An information source that contains data about users, computer files, or other objects. In a file system, a directory stores information about files. In a distributed computing environment (such as a Windows domain), the directory stores information about objects such as printers, fax servers, applications, databases, and users." -
45 fault tolerance
"The ability of computer hardware or software to ensure data integrity when hardware failures occur. Fault-tolerant features appear in many server operating systems and include mirrored volumes, RAID-5 volumes, and server clusters." -
46 full access
"A privilege on a computer system that allows a user to read, write, and delete data." -
47 HDLC
"A protocol for information transfer adopted by the ISO. HDLC is a bit-oriented, synchronous protocol that applies to the data-link (message-packaging) layer (layer 2 of the ISO/OSI reference model) for computer-to-microcomputer communications." -
48 keyboard
An input device consisting of a set of individual keys similar to those on a typewriter. It is used to convey information from a user to a computer or data communications circuit. -
49 network layer
"Layer three of the OSI model. A layer that addresses messages and translates logical addresses and names into physical addresses. It also determines the route from the source to the destination computer and manages traffic problems, such as switching, routing, and controlling the congestion of data packets." -
50 parity bit
"In asynchronous communications, an extra bit used in checking for errors in groups of data bits transferred within or between computer systems. In modem-to-modem communications, a parity bit is often used to check the accuracy with which each character is transmitted." -
51 program
"A set of instructions that a computer uses to perform a specific task, such as word processing, accounting, or data management." -
52 application
"A set of instructions that a computer uses to perform a specific task, such as word processing, accounting, or data management." -
53 recover
"To put back into a stable condition. A computer user may be able to recover lost or damaged data by using a program to search for and salvage whatever information remains in storage. A database may be recovered by restoring its integrity after some problem has damaged it, such as abnormal termination of the database management program." -
54 security
Protection of a computer system and its data from harm or loss. -
55 scanner
An optical input device that uses light-sensing equipment to capture an image on paper or some other object. Captured image data is converted into binary files that can be stored and manipulated by computer programs. -
56 string
A group of characters or character bytes handled as a single entity. Computer programs use strings to store and transmit data and commands. Most programming languages consider strings (such as 2674:gstmn) as distinct from numeric values (such as 470924). -
57 synchronization manager
A tool used to ensure that a file or directory on a client computer contains the same data as a matching file or directory on a server. -
58 wireless LAN
"A local area network (LAN) that sends and receives data via radio, infrared optical signaling, or some other technology that does not require a physical connection between individual nodes and the hub. Wireless LANs are often used in office or factory settings where a user must carry a portable computer from place to place." -
59 connection speed
"The maximum rate, in bits per second, at which data can be transferred between a network and a computer or device." -
60 content header
"Part of the file structure of a Windows Media file that contains information necessary for a client computer to decompress and render the content data. In a packaged file, an additional content header exists and contains the key ID, content ID, and license acquisition URL. This content header can also include a required individualization version number and attributes defined by the content provider."
