Question:

What is DNS and why is it important to the internet?

Joshua M.
Answer:

DNS matches IP addresses to domain names for easier navigation of the web. Think of it as an address book in a phone. Instead of memorizing a contact's number, all you need to do is now their name. DNS works the same way, instead of typing in 199.181.133.5, you can type simply type espn.com.

What is the importance of remarketing in digital advertising?

Joshua M.
Answer:

Remarketing helps target users that have already visited a site but did not make a purchase. It is by far the most effective digital marketing strategy because it targets users that are already interested in your product or service.
