NTP
Network Time Protocol. Used by Internet time servers and their peers to
synchronize clocks, as well as automatically organize and maintain the time
synchronization subnet itself.
RARP
Reverse Address Resolution Protocol. A TCP/IP protocol governing the
translation of a Data-Link Control (DLC) address to an IP address. A request
made to an active RARP daemon initiates a search of the Ethernet Address Table
for an entry matching the unit’s Ethernet address. If a matching entry is found,
the daemon then downloads the IP address to the device. RARP operates within
a single network segment only, i.e. it does not work over routers.
RISC
Reduced Instruction Set Computing. A processor that recognizes only a limited
number of assembly-language instructions.
SAP
Service Advertising Protocol. A network name advertising service that e.g. file
servers can use for advertising their existence to network clients.
SCSI
Small Computer System Interface. A high-speed parallel interface, used to
connect a computer to peripheral devices using just one port.
SLP
Service Location Protocol. A protocol used for advertising and discovering
network services, e.g. printers and CD servers.
SMB
Server Message Blocks. A protocol that makes use of NetBIOS.
SNMP
Simple Network Management Protocol. A TCP/IP protocol for managing and
monitoring nodes on a network.
TCP
Transmission Control Protocol. The connection-oriented, transport-level
protocol used in the TCP/IP suite of protocols.
UDF
Universal Disk Format. A specification developed by OSTA (Optical Storage
Technology Association) for use in optical storage devices. The file format for
DVD.
UNIX
A 32-bit multitasking, multiuser operating system originally developed by
AT&T.
URL
Uniform Resource Locator. A way of specifying the location of publicly available
information on the Internet.
WINS
Windows Internet Name Service. Allows Windows-based clients to locate
NetBIOS resources on TCP/IP networks. When using TCP/IP, the computer
name must be resolved to an IP address. WINS is designed to eliminate the need
for broadcasts in order to resolve computer names to IP addresses. It provides a
dynamic database that maintains computer name to IP address mappings.
Wizard
A form of user assistance that automates a task through a dialog with the user in
order to speed up operation. These tasks are typically complex and require
experience.
