A mask that defines a subnet. See also network mask.
See 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.
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.
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.
Two or more ports are combined as one virtual port, also called
as Link Aggregation.
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.
