usually a hub or a switch. Each connected device has a dedicated‚ point-to-point connection between the device and the hub. The star network topology is by far the most widely implemented topology in use today. Star topology networks require more cabling than bus‚ but the tradeoff comes in the form of a more solid network topology. A break in the network media will only affect a single node‚ since every node has a dedicated connection to the central device; a hub or switch. This also makes the central

building will have a lot of devices that need to be connected to the school campus network and we will need a lot of tools to do it. First off I think since our building is going to be connected to a lot of students I believe that our best choice of cabling to connect to the building will be fiber-optics. This way the students and professors can access whatever they need as fast as possible from any location on campus. On the inside to save money I would run cat5e cables to each individual device.

CHAPTOR 12 In the early 1930s‚ a mathematician developed a formula that could be used to make accurate weather forecasts‚ something that was unheard of at that time. However‚ because there were no computers or calculators at that time‚ it took almost three months of hand calculations to come up with the next day’s forecast. This obviously was far from useful‚ and many individuals scoffed at such a preposterous solution to weather forecasting. However‚ with the introduction of computers by the
