Binary Numbers
splitterless
A type of DSL installation where no splitter is installed, saving
the cost of a service call by the telephone company. Instead,
each jack in the home carries both voice and data, requiring
a microfilter for each telephone to prevent interference from
the data signal. ADSL is usually splitterless; if you are unsure
if your installation has a splitter, ask your DSL provider.
See also splitter, microfilter.
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
subnet's 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.
