15. LANs and WANs : There are tow board categories of networks:
Local Area Network ( LAN ) .
Wide Area Network ( WAN ) .

16. Wide Area Network (WAN):
Span a large geographical area
Require the crossing of public right-of-ways
Rely in part on common carrier circuits
Typically consist of a number of interconnected switching nodes

17. Wide Area Network (WAN):
Alternative technologies used include:
Circuit switching
Packet switching
Frame relay
Asynchronous Transfer Mode (ATM)

18. Local Area Network (LAN):
Smaller scope, typically a single building .
Usually owned by the same organization that owns attached devices .
Internal data rates greater than WANs .
Most common configurations are switched LANs and wireless LANs .

19. The Internet: Internet evolved from ARPANET
Developed to solve the dilemma of communicating across arbitrary, multiple, packet-switched network
TCP/IP provides the foundation

21. Metrics Units The main prefixes we use:
Use powers of 10 for rates, powers of 2 for storage
E.g., 1 Mbps = 1,000,000 bps, 1 KB = 1024 bytes
“B” is for bytes, “b” is for bits
