A Guide to Network Topology January 26th, 2008 • Related Filed Under A network topology is how computers, printers, and other devices are connected over a network. It describes the layout of wires, devices, and routing paths. Essentially there are six different common topologies you should familiarize yourself with: Bus, Ring, Star, Extended Star, Hierarchical, and Mesh. Although it is usually easier to start connecting wires and setting up your network, you’ll appreciate the level of organization these models provide- especially when your network grows in size. And if you’re looking to do well on networking exams, consider these topologies essential to both learn and memorize. Bus Topology The bus topology was fairly popular in the early years of networking. It’s easy to setup- not to mention inexpensive. All devices on the Bus Topology are connected using a single cable. If you need help remembering how the Bus Topology operates, think of it as the route a bus takes throughout a city. It is extremely important to note that both ends of the main cable need to be terminated. If there is no terminator, the signal will bounce back when it reaches the end. The result: a bunch of collisions and noise that will disrupt the entire network. The Bus Topology is less common these days. In fact, this topology is commonly used to network computers via coaxial cable- when’s the last time you can say you’ve done that? Ring Topology

The Ring Topology is a very interesting topology indeed. It is a lot more complex that it may seem- it looks like just a bunch of computers connected in a circle! But behind the scenes, the

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
