a) A technique used to allow external devices to access services on a private network
b) A method for encrypting network traffic
c) A way to assign dynamic IP addresses
d) A tool for monitoring bandwidth usage
Answer:
a) A technique used to allow external devices to access services on a private network
Explanation:
Port forwarding is a networking technique used to allow external devices to access services or devices on a private network. It works by mapping a specific port on a public IP address to a device on the internal network with a private IP address.
This is commonly used for hosting services like gaming servers, web servers, or remote desktop connections, where external users need to access resources on the local network.
Port forwarding helps overcome NAT limitations and allows seamless communication between external devices and the services running on private networks.
