Answer: Inline power switch means that switch can provide current to IP phones

eg:

When you connect an IP phone to a switch using a trunk link, it can cause high CPU utilization in the switches.

As all the VLANs for a particular interface are trunked to the phone, it increases the number of STP instances the switch has to manage.

This increases the CPU utilization.

Trunking also causes unnecessary broadcast / multicast / unknown unicast traffic to hit the phone link

POE is a standard which allows many devices to be powered with only an ethernet cable connection. Access points, IP cameras, even other switches can be POE powered. A POE injector can be used or a POE enabled switch. There are non-standard POE implementations that some cheap IP cameras use that will not work with standard POE hardware.
