- BAUD - a binary event, a signal change from positive to negative or vice versa.
Speed II - At higher speeds a single signal change can transmit more than one bit at a time, so the bit rate will generally be higher that the baud rate.
- Transmission capacity is a function of the frequency, higher frequency means higher capacity
More Speed - Bandwidth = range of frequencies that a channel can support (difference between highest and lowest frequency).
- Greater range means greater bandwidth.
- Greater bandwidth means greater transmission capacity.
Faster Yet - Bandwidth is like pipe diameter.
- Larger diameter pipes can transmit more water in a given period of time.
- Personal Communication Services, PCSs, have a greater bandwidth than fiber optics.
Communications Processors - Star Network
- Bus Network
- Ring Network
Networks - Local Area Network, LAN
- Wide Area Network, WAN
- Value Added Network, VAN
