What is the function of a default gateway in a subnet?

Step 1: Understand what a subnet is. A subnet is a smaller network within a larger network.
Step 2: Know that devices in a subnet can communicate with each other directly.
Step 3: Realize that sometimes devices need to communicate with devices outside their subnet.
Step 4: The default gateway is a device (usually a router) that helps with this communication.
Step 5: When a device wants to send data to an outside destination, it sends the data to the default gateway.
Step 6: The default gateway then forwards the data to the correct destination outside the subnet.
Step 7: This process allows devices in the subnet to access the internet or other networks.
