protocol
A set of rules governing the transmission of data. In order
for a data transmission to work, both ends of the connection
have to follow the rules of the protocol.
remote
In a physically separate location. For example, an employee
away on travel who logs in to the companyʼs intranet is a
remote user.
RJ-45
Registered Jack Standard-45
The 8-pin plug used in transmitting data over phone lines.
Ethernet cabling usually uses this type of connector.
routing
Forwarding data between your network and the Internet
on the most efficient route, based on the dataʼs destination
IP address and current network conditions. A device that
performs routing is called a router.
shaper
The shaper holds back traffic exceeding the configured rate.
subnet
A subnet is a portion of a network. The subnet is
distinguished from the larger network by a subnet mask
which selects some of the computers of the network
and excludes all others. The subnetʼs computers remain
physically connected to the rest of the parent network, but
they are treated as though they were on a separate network.
See also network mask.
subnet mask
A mask that defines a subnet. See also network mask.
TCP
See TCP/IP.
TCP/IP
Transmission Control Protocol/Internet Protocol
The basic protocols used on the Internet. TCP is
responsible for dividing data up into packets for delivery and
reassembling them at the destination, while IP is responsible
for delivering the packets from source to destination. When
TCP and IP are bundled with higher-level applications such
as HTTP, FTP, Telnet, etc., TCP/IP refers to this whole suite
of protocols.
Telnet
An interactive, character-based program used to access a
remote computer. While HTTP (the web protocol) and FTP
only allow you to download files from a remote computer,
Telnet / allows you to log into and use a computer from a
remote location.
TFTP
Trivial File Transfer Protocol
A protocol for file transfers, TFTP is easier to use than File
Transfer Protocol (FTP) but not as capable or secure.
