Question

What is the default Port Number used by HTTP?
1. 89
2. 80
3. 21
4. 23

Answer 1

Correct Answer - Option 2 : 80

The correct answer is 80.

• In computer networking, a port is a communication endpoint.
• At the software level, within an operating system, a port is a logical construct that identifies a specific process or a type of network service.
• Port numbers are sometimes seen in web or other uniform resource locators (URLs).
• By default, HTTP uses port 80 and HTTPS uses port 443, but a URL like http://www.example.com:8080/path/ specifies that the web browser connects instead to port 8080 of the HTTP server.

Types of Protocols:

• Transmission Control Protocol (TCP)
• Internet Protocol (IP)
• User Datagram Protocol (UDP)
• Post office Protocol (POP)
• Simple mail transport Protocol (SMTP)
• File Transfer Protocol (FTP)
• HyperText Transfer Protocol (HTTP).
