Week 5 posting - Subnetting

 Simply put, a subnet is a network inside of a network. You want to use subnetting when you want to separate your networks from each other. For example, a business has computers that the public uses, but they also have computers that are meant only for employee use. The computers for employees have access to more private data that you would not want the general public to have access to, so you create a subnet that separates the public computers from the private computers the employees use. This allows for the data to be contained to just the employees’ computers that need to remain confidential. This also helps allow to control the traffic in the networks allowing for faster speeds in the area of the network you need and bottlenecking the traffic that is not as important.
