What does local name server, mail server and root name server mean and if possible how to find them using the terminal

Description nslookup is a common tool used for querying name servers. A very nice article describing its use on Windows machines may be found on a Microsoft Support site. Using nslookup (or if you'd prefer, the commands dig and host will do the job if they're installed on your computer), please answer the following questions. For each question, please indicate the command typed into nslookup that you used in order to answer the question. - What is the name and IP address of a local name server for Temple? - What is the name and IP address of a local name server for your home ISP? - What is the name and IP address of the mail server for your home ISP? - What are the names of the root name servers (Hint- you'd do the appropriate query for the name ".")
