Give the two types of transmission technology being in widely use and describe their working method please. 3.?what does the store_and_forward mean? 4.Use one sentence to describe functions of each layers in OSI reference model. 5.What job do IP protocol and TCP protocol do respectively? 作业 1, The definination of computer network, client, server, broadcasting, multicasting, unicasting, layers, protocol, peers, interface, network architecture 2, What are the two types of transmission technology? 3, Use one sentence to describe functions of each layers in OSI reference model. 4, The relationship and difference of services to protocols. ● A set of layers and protocols is called a network architecture. ● Between each pair of adjacent layers is an interface. The interface defines which primitive operations and services the lower layer makes available to the upper one. 1.3 Network Software ● A list of protocols used by a certain system, one protocol per layer, is called a protocol stack.
