• Recognize the following logical or physical topologies, given a schematic diagram or description:

  • Star/hierarchical

  • Bus

  • Mesh

  • Ring

  • Wireless

The term network topology refers to the layout of a network. The type of topology affects what networking method is used, as well as what cable types and network devices are required. Topologies are very important, and they serve as the foundation for the information you'll learn in the following sections. You will certainly be asked about topologies on the Network+ exam.

Before we look at the different types of topologies, we must first examine one of the most confusing networking principles: the difference between physical and logical topologies. Then we'll examine the specific physical LAN topologies ...
