Chapter Summary
A switch running in cut-through mode will read a frame’s header and decide where to forward the data before it receives the entire packet
In store and forward mode, switches read the entire data frame and check it for accuracy before transmitting it
In addition to improving bandwidth, switches can create virtual local area networks (VLANs)
A router is a multiport device that can connect dissimilar LANs and WANs running at different transmission speeds and using a variety of protocols
Routers can keep track of where nodes are on a network and can determine the shortest, fastest path between nodes
