How do I find the name of my computer?

In a network environment, nodes (network enabled equipment or objects on the network) have unique identifiers. The MAC address is the physical address of a network interface. It is unique at the hardware manufacturer level, and this hardware address uniquely identifies your computer. 

Physical Address: Refers to the physical address of the Ethernet connection to your computer or server. This may also be your MAC (Media Access Control) Address, Host ID, or Server ID. It is twelve characters long and combines numbers (0–9) and letters (A–F, a–f). Your physical address is often presented in this format: XX-XX-XX-XX-XX-XX.

Each computer with an IP address will also possess a hostname (also known as a Computer Name).

Host Name: The unique identifier that serves as the name of your computer or server.

Below you will find the steps to identifying the hostname of your computer.
