Chapter Summary
Switching is a component of a network’s logical
topology that manages the filtering and
forwarding of packets between nodes on a
network
Ethernet is a networking technology and is by far
the most popular logical topology for LANs today
Ethernet follows a network access method called
CSMA/CD
On heavily trafficked Ethernet networks,
collisions are not uncommon
A switch is a device that can separate a network
into smaller segments, each independent of each
other and supporting its own traffic
