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.
Broadband is a general term used to describe any high-speed, high-bandwidth, “always on” internet connection.
Cable modems, DSL modems, satellite link-ups, and T1 lines are all broadband devices. Dial-up modems and other low-bandwidth devices are called “narrowband.”
