Document Summary
Networks: group of computers & other devices connected via some type of transmission media. Types (processing power decreases as you go down) Wireless (radio frequencies: can be small or large: lan, man, wan, bbn (connects lan to wan) Extranet is private data shared with suppliers etc. Intranet is private data: two possible views. Component view (network from the perspective of components) Switches & routers are intermediary devices (or connectivity devices) Nic (network interface card: provides mac address. Signal weakens as it travels distance, which causes error in transmission (discrepancy between what is sent & received: regenerates signal as it travels. User orientated: os/network os 9os for server machine) Protocols: agreed upon rules for transmitting data between 2 devices, some of these rules handled by hardware, example (switch parts must be compatible with choice of cable) Models that reduce the complexity of data communication between computers.
