Answer 2

3. the company that installed the network card into the computer's motherboard.

Step-by-step explanation:

The MAC or media access control address is a unique address found on all computers and networking devices. It is used by a switch to transfer frames to nodes in a network.

It is a 48 bis or 6 byte address. The first 24 bits is the organisation unique identifier (OUI) while the last 24 bits is uniquely given to a device.

So the company or vendor of a brand can be identified from the Mac address.
