MicroByte Title: Explore caching

Improvement Proposal: DNS TTL (time to live) is a setting that tells the DNS resolver how long to cache a query before requesting a new one. This can be found in result of dig command and can be helpful for identify the cache eviction policy of the DNS resolver.

Benefits of proposed improvements:

  1. Learners will be able to grasp cache terminologies much better for eg. CACHE EVICTION
  2. Learners will understand the importance of DNS TTL .
