PPP Point-to-Point Protocol. Provides a method for transmitting
datagrams over serial router-to-router or host-to-network
connections using synchronous or asynchronous circuits.
protocol Formal set of rules and conventions that specify how information
can be exchanged over a network.
PSTN Public Switched Telephone Network.
repeater Device that regenerates and propagates electrical signals between
two network segments. Also known as a hub.
RFC Request for Comment. Set of documents that specify the
conventions and standards for TCP/IP networking.
RIP Routing Information Protocol. Protocol responsible for distributing

another.
RJ-45 Eight-pin connector used for 10BaseT (twisted pair Ethernet)
networks.
route Path through a network from one node to another. A large
internetwork can have several alternate routes from a source to a
destination.
routing table Table stored in a router or other networking device that records
available routes and distances for remote network destinations.
RTS Request to Send. Circuit activated in hardware flow control when a
computer (or other DTE) is ready to transmit data to a modem (or
other DCE). See CTS, xon/xoff.
serial communication Method of data transmission in which data bits are transmitted
sequentially over a communication channel.
SLIP Serial Line Internet Protocol. Predecessor to PPP that allows
communication over serial point-to-point connections running
TCP/IP. Defined in RFC 1055.
static route Route entered manually in a routing table.
