To communicate with devices on the same subnet, what does a computer need to communicate with?

• A. Its default gateway
• B. The internet
• C. Another device in the network
• D. Any available DNS server

Answer: (A)

The requirement for a computer to communicate with devices on the same subnet is that it needs to interface with another device in that subnet. The reason for this is that a subnet is a logical subdivision of an IP network, and devices on the same subnet can reach each other directly without the need for a gateway. They rely on the subnet's addressing to recognize and send packets to each other. In this context, communication occurs directly between devices that share the same network address and subnet mask, allowing them to send and receive data through local network protocols. The default gateway's role is primarily related to traffic directed out of the local subnet toward external destinations, such as the internet or other subnets. Therefore, while the default gateway is critical for accessing resources outside the local subnet, it is not necessary for communication with another device within the same subnet. Understanding this concept is vital for network communication, as it outlines how devices interact locally before considering broader network infrastructure.
