There is an ongoing conflict between computers and networks. As businesses and homes grow, the number of devices increase, along with the amount of data being transferred. Also, components like switches and Wi-Fi access points are added without regard to the technical capabilities of each device. Inexpensive data switches will cause the network to run at a slower speed when they are added. Wiring and connections also degrade over time, requiring a network be tested to uncover where the choke points are located.
