Glossary A address mask A bit mask used to select bits from an IP address for subnet addressing. The mask is 32 bits long and selects the network portion of the IP address and one or more bits of the local portion. agent 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. ANSI The American National Standards Institute sets standards for the US computer industry.
Glossary B backup Backup is 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. baud 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. BOOTP The Bootstrap Protocol, described in RFCs 951 and 1084, is used for booting diskless nodes.
Glossary D daemon An agent program that runs continuously on a server system in a UNIXr environment and provides resources to client systems on the network. dial-up A temporary, as opposed to dedicated, connection between machines established over a standard phone line. DLL Dynamic Link Library contrasts Terminate and Stay Resident (TSR). Windows automatically loads the applications into memory when required and unloads it when space is needed for other applications.
Glossary driver 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. DSU Data Service Unit. A device that replaces a modem on a digital data service line. The data service unit regenerates the digital signals for transmission over digital facilities. E EIA Electronic Industries Association.
Glossary F file access File access allows users to work with a remote file as if the file is local. FTP File Transfer Protocol. A protocol that allows a user on one host to access, and transfer files to and from, another host over a network. The FTP application is used to provide file transfer services across a wide variety of systems through the use of the File Transfer Protocol (FTP). Usually implemented as application level programs, FTP uses the TELNET and TCP protocols.
Glossary H host Any end-user computer system that connects to a network. Hosts range in size from personal computers to supercomputers. host table An ASCII text file where each line is an entry consisting of one numeric address and one or more names associated with that address. I ICMP Internet Control Message protocol. The ICMP delivers error and control messages from hosts to requesters. An ICMP test can determine whether a destination is reachable and responding.
Glossary IP Internet Protocol. The TCP/IP standard protocol that defines the IP as a unit of information passed across an Internet and provides the basis for packet delivery service. IP includes the ICMP control and error message protocol as an integral part. The entire protocol suite is often referred to as TCP/IP because TCP and IP are the two most fundamental protocols. IP address Internet protocol address. This is a 32-bit address assigned to host on a TCP/IP Internet.
Glossary M manager A software program housed within a network management station. The manager has the ability to query agents, receive agent responses, and set specific variables using various SNMP commands. MIB Management Information Base. The set of variables a gateway running SNMP maintains. Standard, minimal MIBs have been defined, and vendors often have private enterprise MIBs. In theory, any SNMP manager can talk to any SNMP agent with a properly defined MIB.
Glossary NEWT NEWT is a TCP/IP communication stack for Microsoft Windows. NEWT provides users a degree of network access previously only available to workstation and mainframe users. NFS Network File System. A protocol developed by SUNr Microsystems that uses IP to allow a set of computers to access each other’s file systems as if they were local. Originally designed for UNIX systems, this protocol has been implemented on many other operating systems, including DOS and Windows.
Glossary protocol stack A layered set of protocols that work together to provide a set of network functions. R RAM RAM is a Random Access Memory. RFC Request for comment. The RFC documents describe all aspects and issues associated with the Internet protocols. remote Files, devices, and users not attached to your local machine. remote host The computer receiving the network command. remote printer IN LPR/LPD, a printer with a special network card, or a PC or workstation.

A subnet is to a network what a network is to an internet. subnet address The subnet portion of an IP address. In a subnetted network, the host portion of an IP address is split into a subnet portion and a host portion using an address (subnet) mask.
Glossary token ring A type of ring-shaped network that supports high-speed communications between computers. U user id A unique number, created by your system, associated with each user name on a server system. user name A character string, usually assigned by the system administrator that identifies a user on the system.
