why use a network switch
People used to use hubs over switches because switches were much more expensive than hubs, but nowadays it's pretty standard to get a switch if you have several devices on the network since they're both around the same price. dbhosttexas. February 13, 2013 4:14:00 PM.
Each port on the switch has a table associated with it of devices that are connected to that port. In this way, the switch will send the data to the correct device without sending the data out every port. I don't know if this will 'speed' up your network. It will certainly make it more efficient.
