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 — Streaming a video involves DNS and IP, so the answer is 1 and 3.
Explanation
★Streaming a video involves DNS and IP, so the answer is 1 and 3.
★DNS, the Domain Name System, translates a website name into a numeric address.
★IP, the Internet Protocol, delivers the data packets to and from that address.
★Together they let the browser find the server and receive the video stream.
★FTP, the File Transfer Protocol, is used to upload or download whole files, not to stream.
★So the file transfer protocol is not part of ordinary video streaming.
