Document Summary

Workflow control - a business process, but for internal use. Network externality - the larger the network, the more valuable it is. Critical mass: value of being part of network > cost of being on network. Wan - connect several separate locations internet - network of networks. Protocol - set of rules that communicating devices follow. Lan connect through a switch (like an operator) Nic - network interface card, connects to network by implementing proper protocols. Mac - media access control address, unique identifier for each nic. Utp - unshielded twisted pair cable, connect to switch optical fibre cables - light ray signals, for longer distances or heavy traffic. The ethernet protocol (ieee 802. 3) most popular most computers equipped with onboard nic which support 10/100/1000 ethernet speed of transmission allowed. Wireless lan needs a wireless nic (wnic) devices need ap (access points) to connect to switch.
