What service is identified with port 70?

Gopher Services
SMTP
FTP
NTP

The correct answer is: Gopher Services

Port 70 is associated with Gopher services, which is a pre-World Wide Web system designed for distributing, searching, and retrieving documents over the Internet. Gopher operates as a protocol for communication and uses a hierarchical structure to organize different types of online content, allowing users to navigate text-based menus to find information. This makes Gopher the correct association with port 70, as it was specifically designed to use this port for its operations. Other services listed, such as SMTP (Simple Mail Transfer Protocol), FTP (File Transfer Protocol), and NTP (Network Time Protocol), utilize different ports—SMTP typically uses port 25, FTP uses port 21, and NTP uses port 123. Understanding the specific ports associated with various protocols is vital for network management and security analysis, helping practitioners identify and manage data traffic effectively.
