What is the primary port for POP3?

• A. 143
• B. 110
• C. 25
• D. 53

Answer: (B)

The primary port for POP3 (Post Office Protocol version 3) is 110. This protocol is commonly used by email clients to retrieve emails from a server. When a client connects to an email server using POP3, it typically does so through port 110, allowing for the downloading of messages. While port 143 is associated with IMAP (Internet Message Access Protocol) for email retrieval, port 25 is used for SMTP (Simple Mail Transfer Protocol), which is responsible for sending emails. Port 53 is designated for DNS (Domain Name System) services related to translating domain names into IP addresses. Therefore, 110 is the correct choice for POP3, reflecting its standard designation in internet protocols for email retrieval.
