Which port is assigned to the Gopher service?

• A. 70
• B. 80
• C. 53
• D. 7

Answer: (A)

Gopher uses the well-known port 70. This protocol, an early text-based browser for navigating online resources, was assigned port 70 by IANA, so servers offering Gopher services typically listen on that port. When you connect to a host on port 70, you’re usually interacting with a Gopher menu. The other ports map to different services: port 80 is HTTP for the web, port 53 is DNS for name resolution, and port 7 is the Echo service used for simple connectivity tests. Knowing these mappings helps with firewall rules, traffic analysis, and troubleshooting.
