Characteristic
Device(s)
Operates at upper layers to
translate between different
protocol suites
-gateway
Filters traffic based on MAC
address
-bridge
-switch
Introduces the most latency on
a network
-gateway
Boosts the signal but does not
segment the network
–hub
-repeater
Operates differently
depending on whether
nonroutable or routable
protocols are in use
-brouter
Creates broadcast domains
-router
Creates a virtual circuit
between sender and receiver
-switch
Forwards broadcast traffic
-bridge
-switch
-hub and repeater
Filters traffic based on logical
address
-router
-brouter
Associated with the term
“microsegmentation”
-switch
Creates subnetworks
-router

physical star and uses “shared
bandwidth”
–hub

Review Questions Lab 2.3
1. How many collision domains are defined in Figure 2-2?
2. How many collision domains are defined in Figure 2-3?
3. Examine Figure 2-2. If a frame from computer A has a destination MAC address for
computer D, which devices will see the layer 2 information?
4. Examine Figure 2-3. If a frame from computer A has a destination MAC address for
computer D, which devices will see the layer 2 information?
5. Examine Figure 2-3. In terms of network performance, what is the difference
between computers A through H and I through L?
6. What will a bridge and switch do with a frame for which it has no information about
the destination in its table?
7. How do bridges and switches handle broadcast frames?
8. Why is a switch considered more effective than a bridge in terms of increasing
network performance?
