Philips CPWNA100/00 Instructions For Use Manual page 39

Central devices, like a hub, switch, router or wireless access point may be
stand-alone devices or built into a computer.
• A hub has multiple ports and serves as a central connection point for
communication lines from all computers on a wired network. It copies
all data arriving at one port to the other ports. A switch is similar to a
hub, but is able to handle different network speeds at each port.
• Gateway routers and wireless access points route network traffic
from one network to another (e.g. from a wired network to the
Internet, or from a wireless network to a wired network or to the
Internet).
