A printer/display protocol developed by Adobe Corporation. PostScript is
actually a printing and programming language used to display text and
graphics. Unlike line/ASCII printers, which print character input verbatim,
PostScript printers accept an entire PostScript page, and then interpret and
print it. The programming aspects of PostScript can be used to define shapes
and routines that will be used on successive pages, change fonts and text
orientation, and print fine bitmap images within blocks of text.
Any standard method of communicating over a network. There are protocols
for placing actual bits onto the network cable; other protocols are layered on
top from there. LAT is a protocol for network access. TCP and IP are also
protocols (TCP runs on top of the IP layer).
A service configured to offer a Telnet host as a LAT service. The Server can
be set to offer Telnet hosts as services to which LAT users can connect with
the Set/Define Service Virtual command. When the users connect, the Server
translates between the LAT and Telnet sessions. When the user logs out of the
remote Telnet host, he is also disconnected from the Server. A user connecting
"through" the Server in this way consumes a virtual port while connected.
Routing Address Resolution Protocol. RARP allows a node to broadcast a
message asking for an IP address given its hardware address. If a RARP server
has been configured to reply to this node, it will tell the node what its IP
address should be. Note that RARP provides less information than BOOTP,
but is more widely implemented.
A network device that repeats signals from one cable onto one or more other
cables, while restoring signal timing and waveforms. Repeaters are the most
common way to connect local networks together, and can provide either
Thinwire or Thickwire connections. They are commonly used to create larger
local networks up to a certain limit based on the number of repeaters and the
length of the cables.
Request For Comments. An RFC is a standard document describing protocols,
systems, or procedures used by the Internet community. For example, the IP
network protocol is detailed in an RFC (RFC 791), as are SNMP, TCP, Finger,
BOOTP, and the Domain name system. Information on obtaining RFCs is
available from NIC@NIC.DDN.MIL.
Routing Information Protocol. RIP packets, along with SAP packets, allow the
Server to broadcast its known routes and services to the network and obtain this
information from other routers on the network.
An application that provides a terminal interface between (usually UNIX)
hosts using the TCP/IP network protocol. Unlike Telnet, Rlogin assumes the
remote host is or behaves like a UNIX machine. Rlogin can also be configured
to disable login password checking, so should be used with care. See your
host's documentation, especially regarding the .rhosts and hosts.equiv files, for
more information.
