(1) A network authentication protocol that is designed to provide strong authentication for client/server applications by using secret-key cryptography. See also Kerberos ticket.<br />(2) A network authentication protocol that is based on symmetric key cryptography. Kerberos assigns a unique key, called a ticket, to each user who logs on to the network. The ticket is embedded in messages that are sent over the network. The receiver of a message uses the ticket to authenticate the sender.
Industry:Software
(1) A collection of disks that are grouped together for serving media streams. The multimedia file system uses stripe groups to optimize delivery of multimedia assets.<br />(2) The set of disks comprising the storage assigned to a file system.
Industry:Software
(1) A network divided into smaller independent subgroups, which still are interconnected.<br />(2) To divide a network into smaller interconnected, but independent subgroups.
Industry:Software
(1) A collection of equivalent paths. Storage devices may have one - n path groups.<br />(2) In ESA/390 architecture, a set of channel paths that are defined to a control unit as being associated with a single logical partition (LPAR). The channel paths are in a group state and are online with the host. See also logical partition.
Industry:Software
(1) A network infrastructure component to which multiple nodes attach. Unlike a hub, a switch typically has internal bandwidth that is a multiple of link bandwidth and the ability to rapidly switch a node connection from one to another. A typical switch can accommodate several simultaneous full-link bandwidth transmissions between different pairs of nodes.<br />(2) A device that provides connections between telephone lines and trunks.<br />(3) A half-duplex or full-duplex device that detects which devices are attached at each port and passes only frames addressed to those devices on that port. A switch has a small collision domain.
Industry:Software
(1) A collection of files and certain attributes associated with those files.<br />(2) In the hierarchical file system, the underlying system support that manages I/O operations to files and controls the format of information on the storage media. A file system allows applications to create and manage files on storage devices and to perform I/O operations to those files.<br />(3) The collection of files and file management structures on a physical or logical mass storage device, such as a diskette or minidisk.
Industry:Software
(1) A node in a message flow that represents a processing step. A message processing node can be either a primitive or a subflow node.<br />(2) See message flow node.
Industry:Software
(1) A collection of formatted output data produced by chaining several smaller pieces of data. A user builds a logical message by issuing a series of BMS SEND commands.<br />(2) An input or output message that is in a queue associated with a logical rather than a physical terminal. The message queue can be moved, independent of an application, from device to device.
Industry:Software
(1) A Northern Telecom switch.<br />(2) The custom ISDN protocol implemented on the DMS100 switch, providing 23 B-channels and a D-channel over a T1 trunk.
Industry:Software
(1) A collection of hosts and routers, and the interconnecting networks, that are managed by a single administrative authority.<br />(2) A logical collection of resources that is used to separate responsibilities and manage permissions.
