What is a hostname?

A hostname is essentially the unique identifier assigned to a specific device on a network. It serves as a human-readable label that helps users and systems identify and communicate with that device. Hostnames are used in various networking contexts, including in URLs where they correspond to web servers, allowing users to access websites without needing to remember numerical IP addresses.

This identification is fundamental in networking because each device must be distinguishable from others, and a hostname helps to fulfill that role effectively. The significance of the hostname lies in its role in facilitating user-friendly interaction with the network, making it easier to manage and troubleshoot devices within that environment.
