TTL in networking stands for what?

Explanation:
TTL stands for Time to Live. It is a field in the IP header that acts as a hop limit to prevent packets from looping forever. Each router that forwards the packet decreases this value by one; when it reaches zero, the packet is discarded and often an ICMP Time Exceeded message is sent back to the sender. This mechanism keeps networks from wasting bandwidth on misrouted or looping traffic. While the name suggests elapsed time, in practice TTL is a count of hops, not an exact time measurement. (Note: TTL is also used in DNS with a related but separate meaning—the caching duration for a DNS record—but that is a different context.)
