Chapter Summary
A LAN is just two or more network-capable devices connected to each other over a small area through a medium, such as a cable. LAN architecture is the set of rules and design principles that define the LAN. A LAN is made up of three components: physical media, such as the cabling and network interfaces; the topology, such as a star or ring topology; and the protocols, or LAN technologies, such as Token Ring or Ethernet.
The topology of a LAN is characterized by its logical form and its physical shape, such as the shape of a star, ring, or a tree. A star topology is also known as a hub-and-spoke because the connecting point of all devices is at the center of the star, much as the hub of a wheel is the center of the wheel spokes. ...
