the most commonly used digital line in the United States. It carries 24 pulse code modulation (PCM) signals using time-division multiplexing (TDM) at an overall rate of 1.544 million bits per second (Mbps).
is the process of sending short text messages to a device such as a cellular phone, PDA or pager. Text messaging is used for messages that do not tcontain too many characters. The term is usually applied to messages that takes place between two or more mobile devices.
TIFF (Tag Image File Format)

TCP/IP - Transmission Control Protocol/Internet Protocol
the basic communication language or protocol of the Internet. It can also be used as a communications protocol in a private network (either an intranet or an extranet). When you are set up with direct access to the Internet, your computer is provided with a copy of the TCP/IP program just as every other computer that you may send messages to or get information from also has a copy of TCP/IP. TCP/IP is a two-layer program. The higher layer, Transmission Control Protocol, manages the assembling of a message or file into smaller packets (see packet) that are transmitted over the Internet and received by a TCP layer that reassembles the packets into the original message. The lower layer, Internet Protocol, handles the address part of each packet so that it gets to the right destination.
a user command and an underlying TCP/IP protocol for accessing remote computers assuming they have given you permission.
a low-cost, centrally-managed computer devoid of CD-ROM players, diskette drives, and expansion slots.
a local area network (LAN) in which all computers are connected in a ring or star topology and a binary digit- or token-passing scheme is used in order to prevent the collision of data between two computers that want to send messages at the same time. It is the second most widely-used protocol on local area networks after Ethernet.
