SNMP Simple Network Management Protocol
The TCP/IP protocol used for network management.
STP Spanning Tree Protocol
The bridge protocol to avoid packet looping in a complicate
network.
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/SSH 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 / SSH 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.
Trunk Two or more ports are combined as one virtual port, also
called as Link Aggregation.
TTL Time To Live
A field in an IP packet that limits the life span of that packet.
Originally meant as a time duration, the TTL is usually
represented instead as a maximum hop count; each router
that receives a packet decrements this field by one. When
