- What is the difference between packet-switched and circuit-switched networks?
2. Do we need Ethernet MAC if we're using an Ethernet switch to build up a LAN?
Packet switching and circuit switching are two networking methods for transferring data between two nodes or hosts. For a packet-switched network, data is transferred by dividing the data into individual packets and passing it through the circuits to the other host. In packet-switched networks, the route is not exclusively determined when the packets hit the wire. Using routing algorithms, each packet may actually take a different route through the network to arrive at the destination host. Unlike a circuit-switched network where a static route is setup and pre-established prior to initializing connections to the host.
Using an Ethernet switch to build up a LAN should inherently require an Ethernet MAC.
