Name Description
Task Bar: The task bar was introduced with Windows 95 and has been part of every version of Windows since then. It is the bar that spans the bottom of the screen and contains the Start button on the left side and the systray on the right. The task bar also includes the current time on the far right side and can hold shortcuts to programs directly to the right of the Start button.
TCP/IP Stands for "Transmission Control Protocol/Internet Protocol." These two protocols were developed in the early days of the Internet by the U.S. military. The purpose was to allow computers to communicate over long distance networks. The TCP part has to do with the verifying delivery of the packets. The IP part refers to the moving of data packets between nodes. TCP/IP has since then become the foundation of the Internet. Therefore, TCP/IP software is built into all major operating systems, such as Unix, Windows, and the Mac OS.

Template: A template is a file that serves as a starting point for a new document. When you open a template, it is pre-formatted in some way. For example, you might use template in Microsoft Word that is formatted as a business letter. The template would likely have a space for your name and address in the upper left corner, an area for the recipient's address a little below that on the left site, an area for the message body below that, and a spot for your signature at the bottom.
Terabyte: A terabyte is 2 to the 40th power, or 1,099,511,627,776 bytes.
It can be estimated as 10 to the 12th power, or 1,000,000,000,000 bytes. A terabyte is 1,024 gigabytes.
Third Party: Third party software refers to software programs developed by companies other than the operating system developer. It may also refer to third party plug-ins, which are developed by other companies besides the original application developer.
Throughput: Throughput refers to how much data can be transferred from one location to another in a given amount of time. It is used to measure the performance of hard drives and RAM, as well as Internet and network connections.
Throw Distance: Also known as projection distance. Throw distance is the distance from the projector to the screen.
Thumbnail: A thumbnail is the nail on your thumb. If you look at your thumbnail, you will notice it is rather small in size. This is why the term "thumbnail" is also used to refer to a reduced size version of a digital image. While digital thumbnails might not always be as small as a human thumbnail, they are usually less than 200x200 pixels in size.
Title Bar: A title bar is the section at the top of a window that contains the name or description of the window. Nearly all windows displayed on your computer have a title bar. Therefore, if several windows are tiled across the screen at one time, a user can identify each window by just glancing at the title bar. Windows makes this even easier by placing the information from each window's title bar in the Task Bar. Mac OS X displays the title bar information in the middle of each window when the Exposé function is active.
TMDS: Transition Modulated Differential Signaling. A technology for transmitting serial data at very high speeds. TMDS is a core technology used in both DVI and HDMI.
Toolbar: A toolbar is a set of icons or buttons that are part of a software program's interface or an open window. When it is part of a program's interface, the toolbar typically sits directly under the menu bar. For example, Adobe Photoshop includes a toolbar that allows you to adjust settings for each selected tool. If the paintbrush is selected, the toolbar will provide options to change the brush size, opacity, and flow. Microsoft Word has a toolbar with icons that allow you to open, save, and print documents, as well as change the font, text size, and style of the text. Like many programs, the Word toolbar can be customized by adding or deleting options. It can even be moved to different parts of the screen.
Toslink: Toslink is a type of digital audio connection developed by Toshiba Corporation. It uses a fiber optic cable to transmit an audio signal in the form of pulses of light. A single Toslink cable can be used to carry a mono, stereo, or even a surround audio signal.

Toslink is similar to the Sony/Philips Digital Interfance, known as S/PDIF. It provides the same digital audio data as S/PDIF, but uses a light beam instead of an electrical current to send the data. Because the Toslink cable does not use electrical currents, the connection is immune to electrical or magnetic interference. Toslink connections are most commonly found on high-end home theater receivers, MiniDisc players, and professional audio equipment.
Troffer A large recessed luminaire that is typically flush-mounted on a ceiling.

Troubleshooting: Troubleshooting is the process or identifying and fixing problems. Computer troubleshooting may involve hardware or software and can sometimes involve both at the same time. The basic process of troubleshooting is to check the most general possible problems first, and then gradually check for more specific problems. This provides a logical approach to problem solving and can apply to multiple types of products.
TX: TX stands for Transmitter unit. Transmits the signal to the reciver unit.
