Data Communications Model : 30-Jun-19 Networks and Communication Department

Communications Tasks : 30-Jun-19 Networks and Communication Department

Transmission Line : The basic building block of any communications facility is the transmission line. Required capacity , acceptable reliability , minimum cost 30-Jun-19 Networks and Communication Department

Transmission Mediums : Two mediums currently driving the evolution of data communications transmission are: 30-Jun-19 Networks and Communication Department

Networking : Advances in technology have led to greatly increased capacity and the concept of integration, allowing equipment and networks to work simultaneously. 30-Jun-19 Networks and Communication Department

LANs and WANs : There are tow board categories of networks: Local Area Network ( LAN ) . Wide Area Network ( WAN ) . 30-Jun-19 Networks and Communication Department

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 30-Jun-19 Networks and Communication Department

Wide Area Network (WAN): Alternative technologies used include: Circuit switching Packet switching Frame relay Asynchronous Transfer Mode (ATM) 30-Jun-19 Networks and Communication Department

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 . 30-Jun-19 Networks and Communication Department

The Internet: Internet evolved from ARPANET Developed to solve the dilemma of communicating across arbitrary, multiple, packet-switched network TCP/IP provides the foundation 30-Jun-19 Networks and Communication Department

Internet Key Elements: 30-Jun-19 Networks and Communication Department

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 30-Jun-19 Networks and Communication Department
