Mbone is short for multicast backbone on the internet, and is an extension to the internet designed to support IP multicasting, or the transmission of data packets to multiple addresses. Most of this traffic is streaming audio and video which, like radio and TV broadcasts, is sent to many people at once. The Mbone was established in 1994 by the Internet Engineering Task Force.
Mbone is likely to go obsolete with the adoption of IPv6 which supports multicasting by default.
NetCaster was Netscape Communicator’s push delivery system. It was basically a web environment that is always active and can update its onscreen appearance without going to a new URL or reloading. Like all push mechanisms, NetCaster doesn’t require the user to manually check for new content or sit through an update. It let the developer put new content in front of users instead of hoping they come looking for it.
The Netscape Communicator browser ceased development in 2002.
The path tool in Photoshop enables the selecting, identifying, and saving of parts of an image more precisely than the Lasso tool. Using the path tool, you can create an adjustable line connected by dots around a particular area. Once you’ve completed a circle, the path tool will select that area, allowing you to name and save it. The path can then be manipulated just as you’d manipulate a layer.
In computer science, architecture means the conceptual arrangement of a system’s components.
Taking the analogy of a physical building, if a website’s individual pages are rooms, its architecture is the hypertextual relationship between the rooms within the structure.
A bridge (not to be confused with a router) is a data network device used to connect two network segments of different protocols.
For example, if you want computers on a TCP/IP network to talk to computers on a token ring network, you need a bridge to connect the two segments.
