Which component manages the details of communicating with the NIC hardware to send and receive data to and from network media?

device driver

When data is being prepared for transmission onto the network, it is broken into small pieces and a header and trailer are added to each piece to help identify it. What is this process called?

encapsulation

What does a switch do if it doesn't find the destination MAC address in its switching table?

forwards the frame out all ports
