T-1
A dedicated phone connection supporting data rates of 1.544Mbits per second. A
T-1 line actually consists of 24 individual channels, each of which supports
64Kbits per second. Each 64Kbit/second channel can be configured to carry voice
or data traffic.
T-3
A leased-line connection capable of carrying data at 44,736,000 bits-per-second.
This is more than enough to do full-screen, full-motion video.
Tier 1 Carrier
A large telecommunications provider that has large, direct links to the
INTERNET. Small telecoms lease their INTERNET connections through these large
companies. We deal directly with Tier 1 carriers.
TCP
Abbreviation of Transmission Control Protocol, and pronounced as separate
letters. TCP is one of the main protocols in TCP/IP networks. Whereas the IP
protocol deals only with packets, TCP enables two hosts to establish a
connection and exchange streams of data. TCP guarantees delivery of data and
also guarantees that packets will be delivered in the same order in which they
were sent.
TCP/IP
Acronym for Transmission Control Protocol/Internet Protocol, the suite of
communications protocols used to connect hosts on the Internet. TCP/IP uses
several protocols, the two main ones being TCP and IP. TCP/IP is built into the
UNIX operating system and is used by the Internet, making it the de facto
standard for transmitting data over networks. Even network operating systems
that have their own protocols, such as Netware, also support TCP/IP.
Telnet
A method of logging onto remote computer systems using a terminal program or
other applications using the Telnet protocol. You can use the Telnet application
to run commands and programs on a remote computer.
Terabyte
1024 gigabytes.
Terminal
A device that allows you to send commands to a computer somewhere else. At a
minimum, this usually means a keyboard and a display screen and some simple
circuitry. Usually you will use terminal software in a personal computer--the
software pretends to be ("emulates") a physical terminal and allows you to type
commands to a computer somewhere else.
Terminal Server
A special purpose computer that has places to plug in many modems on one side,
and a connection to a LAN or host machine on the other side. Thus the terminal
server does the work of answering the calls and passes the connections on to the
appropriate node . Most terminal servers can provide PPP or SLIP services if
connected to the Internet.
Top Level Domain: (TLD)
A Top Level Domain (TLD) is the uppermost in the hierarchy of domain names. For
example, 1001resources.com is our domain name. The "net" is considered the TLD
and the "1001resources.com" is considered the second level domain. Together they
form a domain name which is unique. There are two types of TLDs. The most common
type is the Generic or Global TLDs which include .COM, .NET, .ORG, .MIL, .INT
and .EDU.
There is a possibility that new gTLDs will be introduced in the near future.
National or ccTLDs are two letter country code domains that are managed by a
registry designated and controlled by each specific country. Each registry might
have differing prices, residency requirements and structure.
Traceroute
A computer program that lists network hosts visited by a packed on the way to
its destination. Very useful for network debugging.
Trademark
As it relates to domain names... a word, phrase or slogan used to identify and
distinguish the source of the goods or services. Trademark law may be different
worldwide. If someone registers a domain name such as Microsoft.To then
Microsoft would need to go to the courts in Tonga to fight to get the name back.
Expensive international litigation is one reason why it is important to protect
your trademarks before someone else registers the names.
Traffic
Data packets being transmitted over a network.
Transfer (Domain Name)
On occasion, domains are sold to another organization or sometimes the name of a
company might change. Most registries require a letter of permission from the
old owner to hand over control to the new owner. The procedures for Transfer of
ownership will depend on the registry.
Trojan Horse
Like the Trojan horse of mythology, Trojan horse viruses hide inside another
program. They are activated when you use the program they are hidden in.
