2 Objectives Understand data communication basics. Know the data transmission speed for communication between computers. Be familiar with local area networks, metropolitan area networks, wide area networks, and the Internet of networks. Understand the two main local area network protocols-- Token-Ring and Ethernet. Understand the data communication services provided by public telephone systems, also known as common carriers. Be familiar with communications hardware that supports networking.
3 Communication Basics Computer communications is at three levels Application level Computer level Communication channel Protocol Set of rules for communications OSI Standard 10-3
4 OSI Reference Model Layer Name Purpose 7 Application Layer Application-to-application communication 6 Presentation Layer Manage data representation conversions 5 Session Layer Establish and maintain communication channel 4 Transport Layer Guarantee end-to-end integrity of transmission 3 Network Layer Route data between network addresses 2 Data Link Layer Move data from one network address to another 1 Physical Layer Put data onto and off of the network media 10-4
