Networks may be laid out in a number of different fashions. The arrangement of devices on a network is known as a network topology and are commonly described using the shapes that the topology results in when drawn on a network diagram. In this video, explore the common network topologies.
- [Instructor] Networks may be laid out…in a number of different fashions.…The arrangement of devices on a network is known…as the network topology.…And network topologies are commonly described…using the shapes that the topology results in…when drawn on a network diagram.…The simplest network topology is called the bus network.…In a bus network every device is attached to a single wire,…and everything that any device sends…on the network is received by all other devices…on the network.…
Devices simply ignore anything that they receive…that isn't addressed to them.…The original Ethernet design was intended…for use on bus networks.…And bus networks were commonly used…because they were both inexpensive and easy to wire.…However, the bus network has very significant limitations.…First, only a single system on the network can transmit…at any given time.…Second, bus networks depend upon a single wire,…which if broken severs the network.…
And finally, bus networks pose a security issue…because any device on the network can eavesdrop…
