The 'hostname' command displays the name of the system or machine on the network, which is crucial for identifying devices within a network. When you run the command, it returns the configured hostname, allowing users and systems to recognize and communicate with that particular system. The hostname is often used in network configurations and is essential for various networking tasks, including connecting devices and performing administrative functions.
