Hubs – less expensive, used in a very small LAN where low throughput is OK
Switches – segments collision domains, interconnects network segments, more expensive, but performance makes it cost effective.
Each type has advantages/disadvantages:
Cable length, cost, bandwidth, ease of installation, susceptible to EMI/RFI
Attenuation: the decrease in signal strength along an electrical or optical cable.
