When watching videos from a website using streaming technology, which of the following will be involved? Choose the correct answer from the options given below.

1.DNS

2.FTP

3.IP

A1 and 2 only

B1 and 3 only ✓ Correct

C2 and 3 only

D1, 2 and 3

Correct answer: (B) 1 and 3 only

Explanation

Statement 1 is involved because DNS resolves the site's domain name into the server's IP address.

Statement 3 is involved because IP delivers the video packets across the network to the viewer.

Statement 2 is not involved since FTP is a file transfer protocol, not what carries streamed media.

Streaming plays the content as it arrives rather than downloading a whole file first.

Streaming typically rides on HTTP or dedicated streaming protocols over IP.

The DNS lookup happens first so the browser knows which server to contact.
