Compare and contrast the function of hubs and switches. Be as detailed as possible. Explain the advan tage of one device over the other
What will be an ideal response?
A hub is a Layer 1 device, whereas a switch is a Layer 2 device. Hubs do not filter frames. They flood
all the frames they receive on one port out all other ports. Hubs do not segment networks. All of the
ports of a hub are part of one collision domain. Hubs are less expensive and less efficient than switch
es. Hubs should be used in small LANs.
Switches are Layer 2 devices. They filter frames. Switches segment networks into multiple collision
domains. Each switch port is its own collision domain. Switches are more expensive than hubs but use
bandwidth more efficiently. They also allow for the interconnection of segments with different speeds.
