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

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

Answer: (A)

Sending information from one network to another relies on network (logical) addressing. Addresses that identify the destination network and the specific host allow routers to determine the next hop and forward the packet toward its destination, potentially across multiple networks. When the packet finally reaches the destination network, it can be delivered to the exact device using its MAC address on the local link. The subnet mask plays a supporting role by helping decide whether the destination is on the same local network or requires routing, but it doesn’t move data between networks by itself. Port addressing, meanwhile, is about directing data to the correct application on a host, not about routing across networks.
