Document Summary

Wired and wireless lan components: clients and servers, network interface cards (nics aka network adapters) : provide mac addresses to computers on wired and wireless lans. Overlay network: illustrations: overlay: this network combines wire based with wireless portion, lhs: access layer switch that connects to ap, server and client (which is mobile) will be accessing printers, computers, etc. through the ap. Switch: both devices allow for data to be sent and received. Their logical topology is error free different (bus or star) Ethernet: meet the requirement, and stay within budget. No need to pay more for fibre optic if tp is good enough: combining different nominal data rates requires multiple speed devices, implication for security: switches should be secured in locked closets. Rarely used today: request and clear to send, the ap will act as a manager, and everyone that needs to send data needs request it.
