Adding Excitement to your Presentations Network - a communication system between computers. Bandwidth - the amount of information that can be sent through a network in a fixed amount of time. High bandwidth means the picture and sound will be clearer. Digital vs. analog information - digital data are represented by discrete values. Analog information is represented by ranges of values, and is therefore less precise.
Computers use digital data.
Because your computer only understands digital data, your modem converts analog data to digital and vise versa. The bandwidth is shared by all the users, so the effective speed of communication depends on how many people are currently using the network. Ethernet is the primary type of networking used in the Internet. Dedicated Lines - special cables used only for videoconferencing, usually within an office or school. Compression - the computer equivalent of saying the same thing with fewer words.
