Rfid tagging is an iot technology that allows assets to be tracked using electromagnetic fields to automatically identify tagged objects. rfid tags have two main categories: passive tags, which are powered by collecting radio waves from a nearby reader, and another type that is self-powered with a battery and can be read at further distances. what is this other type of rfid tag called?

The Active Tags

Explanation:

They have that name doe to that this tags are self-powered by using batery, giving them independence from the reader, because don't need its energy to work, this characteristic allows to work at distances that can reach about 100 meters, but they are also more expensive, bigger and heavier because of the batery and the transmitter

given the options, i would say your best bet is c. the modem supports up to 56 kbps, which is too low for video streaming. dial up modems use actual phone lines, which only can go up to 56 kbps as that's more than sufficient for traditional phone calls. this is also the reason why when a dial-up modem connects, you hear all those sounds. it's literally using the phone line to establish a connection.
