|Bandwidth|,|bandwidth|,|<P>The data transfer capacity of a digital communications system, such as the Internet or a local area network (LAN). Bandwidth is usually expressed in the number of bits that a system is capable of transferring in a second: bits per second (bps). High bandwidth or broadband refers to a network capable of a fast data transfer rate.|
|Bitrate|,|bit rate|,|<P>The speed at which digital audio and video content streams from a source, such as a file, to be rendered properly by a player, or the speed at which binary content in general is streamed on a network. Bit rate is usually measured in kilobits per second (Kbps), for example, 28.8 Kbps. The bit rate of a Windows Media file or live stream is determined during the encoding process, when the streaming content is created. Bandwidth is the total bit-rate capacity of a network. For audio and video content to render properly when streaming over a network, the bandwidth of the network must be high enough to accommodate the bit rates of all the different content that is being streamed concurrently.|
|Broadcast|,|broadcast|,|<P>Describes how a client experiences receiving a stream. A broadcast stream can be unicast or multicast. In a broadcast connection, the client is passive and does not control when the stream starts or stops. In an on-demand connection, the client is active and controls when the stream is started and stopped.|
|Broadcastmulticast|,|broadcast multicast|,|<P>Delivery of one stream by a Windows Media server to many clients. From a client perspective, a broadcast is a connectionless experience because the client never connects to a Windows Media server.|

|codec|,|codec|,|<P>Short for compressor/decompressor. Codecs are various types of computer algorithms that are applied to audio, video, and image files to compress the size of the files. The benefit of this is that the files do not use as much disk space when stored or network bandwidth when streamed. To open a compressed file, the same codec must be used to decompress the file. If your computer does not have the correct codec to decompress a file, Windows Media Player will attempt to download the codec for you. |
|CompactMode|,|compact mode|,|<P>Windows Media Player can appear in two modes: full mode or compact mode. Compact mode is the smaller, reduced-functionality mode that is customizable.

|port|,|port|,|<P>A number that enables IP packets to be sent to a particular process on a computer connected to a network. Ports are most often identified with a particular service. For example, port 80 on an Internet computer indicates a Web server. Windows Media server components, when in use, bind to particular ports. By default, the Windows Media Unicast service binds to port 1755 and the Windows Media Station service binds to port 7007.
