A GUID (Globally Unique Identifier) is a 128-bit number used to identify resources or objects in a computer system. GUIDs are often used in software development to generate unique identifiers for objects such as files, folders, and database records. They are also used in hardware devices to identify the device.
There are several ways to check a GUID. One way is to use the “Get-Guid” cmdlet in PowerShell. Another way is to use the “uuidgen” command in Linux. You can also use a GUID generator website to generate and check GUIDs.
