Why do we need packets of data?
Data packets. The main purpose of networking is to share data between computers. A file has to be broken up into small chunks of data known as data packets in order to be transmitted over a network.
Which device has the most network ports?
hub

Does the type of USB port matter?
Generally, you can plug standard devices like mice and keyboards into a USB 2.0 port, as speed isn’t a priority for them. But any devices that will transfer data, like an external hard drive, should be plugged into a USB 3 port for best results.
