The computer name, also called device name orhost name, is used to identify a computer in a network. For computers with a pre-installed operating system, the random working name of a computer (e.g. “DESKTOP-BRA0TN”) is already predefined. However, if the computer is part of a computer network, each device needs a unique and unambiguous name, because double naming in a computer network can interfere with data transfers, IT infrastructure, and overall problem-solving.
That’s why it’s sometimes necessary to change the computer name manually. However, this can only be done if you know how to find out the name of your computer.
