22. Network Types and Protocols
Local area networks (LANs) connect computers within close proximity
LANs are the most common types of networks
Metropolitan area networks (MANs) connect computers separated by moderate distances
Wide area networks (WANs) typically connect computers between cities, across countries, or even around the world
Guide to MCSE , Enhanced

23. Network Types and Protocols (continued)
A network protocol packages information into packets
A media access method sends packets onto the media itself
IPv4
Most common LAN protocol used today
Also the standard protocol used to transmit information over the internet
