What is used to send information from one network to another network?

• A. MAC Address
• B. IP Address
• C. Subnet Mask
• D. Network or Logical Addressing

Answer: (D)

Sending information from one network to another relies on network or logical addressing. This is the addressing scheme used by routers to determine the next hop toward the destination, allowing packets to be forwarded across multiple networks. In practice, a device places the destination IP address in the packet and uses the gateway’s MAC address on the local link to reach the router; the router then uses the destination IP to route the data onward. MAC addresses stay within a single local network and aren’t used for inter-network routing, while a subnet mask helps decide whether a destination is on the same network but doesn’t perform the inter-network delivery itself. So the concept of network or logical addressing is what enables communication between different networks.
