Document Summary

Types of computers: (descending order by processing power) Wire-based is either twisted pair or fiber optics. Backbone network (bbn) -> high-speed network that (cid:272)onne(cid:272)ts different lan"s together or different. Extranet: access is partially public (allows controlled access) Note: we use fi(cid:271)er opti(cid:272)s (cid:271)etween (cid:271)uildings (cid:271)e(cid:272)ause it"s faster and safer. Best practise is to use switches: distribution layer. It is a bbn that connects lans together. Best practise is to use switches: core layer. It is a bbn that interconnects different bbns. Nic (network interface card: uses a specific format to transfer bits, provide mac address (medium access control) to interface with network. Switch: forwards data from a sending computer to a receiving computer. Repeaters: boosts a network signal to travel much further. Attenuation: it is the weakening of a signal as it travels. Network operating systems: it is the operating system for a server: who access/use which file or folder in the network, manage traffic.
