They need to be connected via routers/links to make an internetwork. The above internetwork is made of 5 networks: 4 LANs and 1 WAN. E.g. If host A needs to send a data packet to host D, the packet needs to go from A to S1, then from S1 to S3, and finally from S3 to D. Therefore the packet passes through 3 links.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
