Apple computer's proprietary LAN for linking Macintosh computers and peripherals. The difference between the highest and lowest frequencies of a transmission channel. A measure of the information capacity of the transmission channel.
Bridges connect LANs with different hardware and different protocols.
Bridges are best used to break a large network into smaller networks, while allowing the individual networks to share the same resources. On LANs, all workstations and devices receive the message. Both parties then have to retransmit their information. In most systems, a built-in delay ensures that the collision does not occur again. The whole process takes fractions of a second.
