### Activities in this Lesson

• Use this video to establish the analogy of the computer network function with the transportation of vehicle through roads and highways. Many small lanes are connected to road which provide access to highways.  Transfer of traffic takes place at the interconnection of roads with highways. Explain the  analogy of highway transportation and information transfer.

The primary function of a network is to transfer information from a source to destination. Its basic capability is to provide "connectivity" for information (data, voice, video, bits, characters, etc.) to flow among the users through the "transmission systems" (made using various media such as wires, ables, radio, optical fiber, etc.)

• Use the following project to introduce the concept of network topology to the students. This project uses cities and freeways interconnected to allow traffic to flow. The cities can represent computers, and the freeways can represent media. The connection of media and computers will represent the different types of network topologies.

Teacher give the  instructions on the first page of the attached file to the students, and answer questions if need it.

Students answer the worksheet base on the assumptions.

Teacher helps the students to analyze the 4 possible configurations of connecting cities with freeways, and relate the concepts to network topologies.
