6700-A2-GB22-20
A 32-bit mask used to identify the network and local portions of an IP address.
A software program housed within a managed network device, such as a host, gateway, or
terminal server. An agent stores management data and responds to the manager's data
requests.
American National Standards Institute. A member of ISO, ANSI accredits and implements
standards.
Address Resolution Protocol. Part of the TCP/IP suite, ARP dynamically links an IP
address with a physical hardware address.
American Standard Code for Information Interchange. The standard for data transmission
over telephone lines. A 7-bit code establishes compatibility between data services. The
ASCII code consists of 32 control characters (nondisplayed) and 96 displayed characters.
The process of preserving copies of files on a different drive, directory, or media to protect
against the destruction or loss of the original files in the event of hardware or system
failure.
A unit of signaling speed that is equal to the number of symbols per second. This is not
necessarily the same as bits per second, although the terms are frequently interchanged.
The Bootstrap Protocol. Described in RFCs 951 and 1084, it is used for booting diskless
nodes.
A temporary storage area used to compensate for differences in data flow rate when
transmitting data from one device to another.
A device that receives a specific service, such as database management, from a server.
An agent program that runs continuously on a server system in a UNIX environment and
provides resources to client systems on the network.
A factory-preset value that is assumed to be correct unless changed by the user.
A unique label that identifies the device. The device name must be unique to all other
network element names (sites, carriers, devices, device groups, cabinets, and models).
Can also be a logical name equated to a physical device name.
A temporary, as opposed to dedicated, connection between machines established over a
standard phone line.
Dynamic Link Library. Unlike Terminate and Stay Resident applications, DLLs are
automatically loaded into memory when required and unloaded when space is needed for
other applications.
Domain Name System. An online distributed database that maps machine names into IP
addresses.
A named group of machines on the network. A domain name consists of a sequence of
names (labels) separated by periods (dots).
A software module that controls an input/output port or external device such as a keyboard
or a monitor. TCP/IP uses a driver to control the network interface cards.
