Telephony
Traditional voice communication
Use telephones
All telephones and subscribers share the
telephone network
Thus constrained by peak load
Today telephone industries use the term
telecommunications to refer to
transmission of voice, video, image anddata across today's telephone
infrastructure (Skype)

LAN
Consists of a shared transmission medium and
a set of hardware and software for interfacing
devices to the medium and regulating the
orderly access to the medium Topologies: ring, bus, tree, and star
Usually owned by the organization using the
network to interconnect equipment
