TTL stands for Time To Live in the context of DNS (Domain Name System). It is a value in DNS records that determines how long the record should be kept in a server's cache. Here are the steps to understand it:

1. DNS is like the phonebook of the internet. It translates human-friendly domain names (like "google.com") into IP addresses that computers use to identify each other.

2. When a server looks up a DNS record, it stores that record in its cache so it doesn't have to look it up again next time. This speeds up the process and reduces the load on the DNS system.

3. However, these records can't be stored forever. Information changes, and the server needs to get the updated records from time to time. This is where TTL comes in.

4. The TTL is a value in each DNS record that tells the server how long to keep that record in its cache. The value is in seconds. For example, a TTL of 3600 means the server should keep the record for one hour.

5. After the TTL has passed, the server will discard the cached record. The next time it needs that record, it will fetch the updated record from the DNS system.

6. This ensures that the server always has relatively up-to-date information, while still benefiting from the speed and efficiency of caching.
