What Is Port 80?
Port 80 is a communication endpoint on your computer that allows incoming and outgoing data to be transmitted over the internet. It is the default port for HTTP (Hypertext Transfer Protocol) traffic, which is used to access websites, web applications, and online services. When you enter a URL into your web browser, your computer sends an HTTP request to the server hosting the website, and the server responds with the requested data, which is then displayed in your browser.
How Does Port 80 Work?
Here’s a simplified overview of the process:
- When you request a website, your computer sends an HTTP request to the server hosting the website.
- The request is sent to the server’s IP address, along with the port number (in this case, port 80).
- The server receives the request, processes it, and sends the response back to your computer.
- Your computer receives the response and displays the website in your browser.
