T

TAFN: Chat and newsgroup abbreviation of "That's all for now." TTFN is the Tigger variation, "Ta-ta for now."

Tangible product: "Tangible" means you can touch it. Most things we think of as "products" (such as Big Macs) are physical. An intangible product would be a service.

Target audience: The people most likely to buy your product or service, or most interested in the information you provide. The more you know about them, and have designed your product or service with them in mind, the easier it will be to sell it to them.

TCP/IP: Transmission Control Protocol/Internet Protocol. A language allowing different types of computers to communicate over a network. It's how computers talk over the Internet, and sometimes even Local Area Networks.

Telnet: A command-driven access to information on the Internet. I recommend ignoring it unless your job requires you to use it or you already understand it. Like gopher, it was around before the World Wide Web, and is being replaced by simpler methods of accessing information.

THX: "Thanks."

TIA: Abbreviation for "Thanks in advance." I don't recommend you use it with your business email responses!

TPTB: Abbreviation for "The Powers That Be."

TTYL: Chat abbreviation for "Talk to you later." TLK2UL8R is a longer variation. They both mean exactly the same thing.
