INTERNETWORKING BASICS
The primary advantage of bridging is increased bandwidth available on a segment
because of the decreased number of devices in the collision domain.
Switches have the same basic functionality as bridges but usually have more ports.
Each switch port is a separate collision domain, and each port provides dedicated
bandwidth.
Virtual local area networks (VLANs) can be used to make a group of switch ports into
a separate, isolated LAN. Routing is required for communication between VLANs.
VLANs can function across multiple switches when they are connected by a trunk
connection. Inter-switch linking (ISL) is used to create a trunk connection between
Fast Ethernet ports on Cisco switches.
Switches make it possible to run Ethernet devices in full-duplex mode. In full-duplex
mode, two devices share the Ethernet wire exclusively, enabling faster throughput
because no collisions are possible.
Store-and-forward switching reads the entire frame before making a forwarding
decision; cut-through switching reads only the first six bytes - the destination media
access control (MAC) address - to make a forwarding decision. Store-and-forward
switching performs error checking; cut-through switching does not.
The primary advantages of routers are:
l Allow you to connect dissimilar LANs
l Provide multiple paths to a destination network
l Allow the interconnection of large and complex networks
Connection-oriented communication uses a nonpermanent path for data transfer. It

involves three steps: establish the connection, transfer the data, and terminate the
