Network topology year 9 week 6
- 2. This lesson describes designs for connecting computers. You will also learn about variations that are often used and what you need to consider when planning your network.
- 3. After this lesson, you will be able to: • Identify the four standard topologies and their variations. • Determine an appropriate topology for a given Case Study.
- 4. Designing a Network Topology • network topology = the arrangement or physical layout of computers, cables, and other components on the network. • "Topology" is the standard term that most network professionals use when they refer to the network's basic design.
- 5. A network's topology affects its capabilities. The choice of one topology over another will have an impact on the: 1. Type of equipment the network needs. 2. Capabilities of the equipment. 3. Growth of the network. 4. Way the network is managed.
- 6. Developing a sense of how to use the different topologies is a key to understanding the capabilities of the different types of networks. Before computers can share resources or perform other communication tasks they must be connected. Most networks use cable to connect one computer to another.
- 7. A small, independent, business/home/life insurance company consisting of an owner, a business manager, an administrator, and four agents decides to implement a network. The company occupies half of a small building in an office park. Their volume of business had been stable for the past three years, but recently it has been increasing. To handle the increased business volume, two new agents will be hired. Figure 1 illustrates the current arrangement.
- 9. Everyone in the company has a computer, but the business manager has the only printer. These computers are not connected by any form of networking. When agents need to print a document, they must first copy the file to a floppy disk, then carry it to the business manager's computer, where they are finally able to print it. Similarly, when staff members want to share data, the only means available is to copy the data on one computer to a floppy disk and insert the disk in another computer.
- 10. Recently, problems have arisen. The business manager is spending too much time printing other people's documents; and it is frequently unclear which copy of a given document is the current and authoritative version. Your task is to design a network for this company. Draw a proper topology on your Ms Word and explain why.
