Unless otherwise specified, computers and laptops are given an automatically generated, alphanumeric name when the operating system is installed. The PC name, also known as the device name or host name, identifies your PC within a network of computers. The random computer name (e.g., ‘LAPTOP-QO1XB2’) is basically meaningless and is used only to identify the computer individually.
Private individuals who do not want to connect their PC to a network of work computers rarely know how to change the PC name. In private use, this name usually plays no significant role. However, if you use your computer as part of a workgroup of computers or if you use different PCsvia the home network, the randomly generated PC name isn’t very meaningful and doesn’t provide any information about the role of the PC within the network or about the user.
In these cases, finding out how to change the name of your computer and renaming it can come in handy.
