Nice overview of a network switch. However, you missed one very important IP device: a VoIP phone. A lot of companies will run PoE to the VoIP phone and then plug the PC into the VoIP phone’s second Ethernet port. This way, they only have to run one Ethernet cable per cubicle and can keep the phones powered up during a power outage; if they have a UPS powering the network switch.
