First, the purpose of the experiment 1. Master the concept of network topology structure. 2. Understand the main factors to consider when choosing a network topology. 3. Recognize several common network topologies. 4. Master the basic methods of accessing information by using a browser to access the Internet. Second, the content of the experiment 1. Understand the software and hardware information of the network used in the experiment; 2. Draw the network topology diagram of the computer room; 3. Learn to use IE to access the teaching aids site in the Internet, using search engines to search for some of their own learning resources to help. Third, the experiment step the method and form of each node connection in the network is called the network topology structure. Generally speaking, the common network topology has bus type, star type, ring type, net type four kinds. The main factors to consider when choosing a network topology are reliability, economy, and flexibility. In the experiment, students can carefully observe the network equipment in the computer room, understand the network by which hardware equipment (equipment name, function, main technical indicators), run what kind of network operating system, understand the network size and network type, and the network to provide what services. And in each other on "What is the computer network" discussion, set up a computer network preliminary concept, as well as the concept of interconnection network platform. Careful observation, careful inquiry, determine the network type of experiment selection, and draw the network topology diagram of laboratory room. The characteristics of the topological structure are analyzed and discussed. In the course of the experiment encountered not understand the problem, through Internet search engines such as Baidu http://www.baidu.com search related knowledge. Four, study questions 1. What is a computer network. Imagine the computer network after 50 years. 2. According to your observation, the computer room used some kind of network equipment and network software. List their information. 3. What type of network is selected in the computer room. What is the feature of this topology? Draw a diagram of its topological structure. 4. You use search engines to find out which learning resources are available. Briefly listed and explained.
1, the computer network in layman's terms is by many computers (or other computer network equipment) through the transmission media and software physical (or logical) connected together. In general, the composition of computer network basically includes: computer, network operating system, transmission medium (can be tangible, can also be intangible, such as wireless network transmission medium is air) and the corresponding application software four parts.
50 years from now, it may be wireless coverage of the world, where people can communicate through satellite networks.
2, network equipment has d-link DES-3526 (workgroup level, two layer, can network management switch, Gigabit switch, two-layer switch backplane Bandwidth 8.8Gbps Interface number 24), Server (Kai Day DR335), PC Software has Microsoft Web Publishing Tencent software Microsoft SQL Server U8 management software [V8.50] and so on
3, topological star-type Cascade 3,
4, Baidu Encyclopedia computer Network and related topology knowledge, as well as through Pacific Internet find d-link DES-3526 parameters
