A network that spans over long distance. A way to lay out a network. You must know basic network topologies. For example token ring network uses physical star topology and logical ring topology. Mesh topology is the most difficult and expensive to implement but it offers greatest reliability and redundancy.
Ethernet network are logical bus topologies, but can have physical star or bus topologies.
The following table outlines the network devices and their functions. To install the NIC card you must have available IRQ in the computer. MAU Multistation access unit. Acts as u hub in Token ring networks. Repeater Repeaters are used to extend segment beyond the limitation of the maximum allowed cable length.
