Network devices for wired network communication
Hub
An Ethernet hub acts as a multiport repeater that receives an incoming electrical signal (data) on a port. It then immediately forwards a regenerated signal out all other ports.
Hubs use physical layer processing to forward data.
Switch
LAN switches are essentially multiport bridges that connect devices into a star topology. Like bridges, switches segment a LAN into separate collision domains, one for each switch port.
A switch makes forwarding decisions based on Ethernet MAC addresses.
Router
Provides path determination and packet forwarding
Responsible for encapsulating and deen capsulating packets.
Uses a routing table to determine the best path to use to send packets to a specified network.
Network devices for wireless network communication
Wireless LAN controller
Simplifies configuration and monitoring of numerous APs.
Controls and manages the functions of the APs on a network.
Access Point
Small network
usually a wireless router that integrates the functions of a router.
Large Network
can be many APs
