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 the TTL
reaches zero, the packet is discarded.
twisted pair
The ordinary copper telephone wiring long used by telephone
companies. It contains one or more wire pairs twisted together to
reduce inductance and noise. Each telephone line uses one pair.
In homes, it is most often installed with two pairs. For Ethernet
LANs, a higher grade called Category 3 (CAT 3) is used for
10BASE-T networks, and an even higher grade called Category
5 (CAT 5) is used for 100BASE-T networks.
