Defining Networks• Information is usually transmitted between
computers via different types of media
• Media attaches to a computer system through adapter
• Network:
• Consists of two or more computers that can exchange information through a medium
• Servers share information or other resources
• Clients access shared resources

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 70-291, Enhanced23
Network Types and Protocols (continued)
• A network protocol packages information into packets
• A media access method sends packets onto the media itself
