Abstract: Grid computer is one of the trends of the future computer architectures, and the grid-enabled components are the key elements of the grid computer system. The main characteristics of the grid-enabled component are grid entity, functional service and intelligent interconnection, and the key issues in the grid-enabling technology of the computer components include device description, interconnection, resource sharing and multiplexing, security etc. The gDevice protocol is a protocol intending for the grid-enabling of the computer peripherals. The protocol has been partly validated in a grid computer console system called grid console.
