  • Patent number: 5745682
    Abstract: A computer station location method and apparatus is disclosed which is efficient, simple and reliable. The invention utilizes a location code to indicate a physical location of a computer station of interest on a computer network. When users connect to the computer network, the users will specify location codes indicative of the physical locations of the particular computer stations on which the users are operating. The location codes are stored in name tables of the computer stations if those location codes are unique, i.e., not stored in the name tables of any computer station on the computer network. To determine the physical location of a computer station of interest, an interrogation of the name table of the computer station of interest is performed using the hexadecimal address of the computer station of interest.
