MAC - Company Id
The MAC address (Media Access Control) is the unique hardware number of your computer. (On the local Ethernet network, this is the same as your Ethernet address.) When you connect to the Internet from your computer, the matching table associates your IP address with the physical (MAC) on the local network.
For each physical device connected to the network, there is a unique MAC address.

In information technology, a protocol is a special set of rules that use nodes in a telecommunications connection when they communicate. Protocols define the interaction between transmitting entities.
Protocols exist on several levels in a telecommunications connection. For example, there are protocols for exchanging data at the hardware device level and communication protocols at the application program level. In a standard model known as Open Systems Interconnection (OSI), at each level of telecommunications exchange there is one or more protocols that must be recognized and participate in network communication. Protocols are often described in a sectoral or international standard.
