A hostname is the label of any machine that identifies the system by which the system can be accessed from the network. The hostname of any system is a simple string consisting of letters, numbers, dots, and hyphens. The system hostname can be assigned in two main ways, the first way you can set the hostname while installing the operating system and second you can change the hostname from the command line by logging into the system with the root account.
