Protocol:
Any standard method of communicating over a network.
Remote Access:
Access to network resources not located on the same physical Ethernet. (Physical Ethernet here refers
to an entire site network topology.)
Remote Control:
Form of remote access where a device dialing in assumes control of another network node - all
keystrokes on the remote are translated into keystrokes on the network node. Used primarily with IPX
protocol.
Remote Node:
Form of remote access where the device dialing in acts as a peer on the target network. Used with both
IP and IPX protocols.
Repeater:
A repeater is a network device that repeats signals from one cable onto one or more other cables, while
restoring signal timing and waveforms.
Ring:
A network topology in which the nodes are connected in a closed loop. Data is transmitted from node
to node around the loop, always in the same direction.
RMON:
SNMP-based standard for reporting various network conditions. RMON has 10 different management
groups which provide detailed information about a network.
Rlogin:
Rlogin is an application that provides a terminal interface between UNIX hosts using the TCP/IP
network protocol. Unlike Telnet, Rlogin assumes the remote host is (or behaves like) a UNIX machine
ROM:
Read-Only Memory, a memory device that retains its information even when power to it is removed. A
ROM version of a network device does not need to download, since the ROM contains the entire
executable code and thus never needs to reload it. Frequently the ROM is provided as "flash ROM",
which can be reprogrammed by downloading if the user chooses.
