(In order to ensure the security of the system, this cabling system plan needs to realize the isolation of the internal and external networks, so it is necessary to deploy two sets of systems for the computer network system, one for the internal working network and the other for connecting to the external Internet. Therefore, the total number of information points in the equipment computer network should be 154, including 77 information points for internal network equipment and 77 information points for external network equipment.)
