The port number is a numerical identifier used to differentiate different applications or services that are running on the same computer. It is like a street address for a computer, allowing it to receive data from other computers. For example, web servers usually use port 80 to receive data from web browsers. Similarly, email servers use port 25 for incoming emails.
TCP/IP, or Transmission Control Protocol/Internet Protocol, is a set of communications protocols used to connect hosts on the Internet or a network. It is the primary set of protocols used to connect computers to the Internet. TCP/IP is responsible for ensuring that data is correctly formatted, addressed, transmitted, routed, and received.
For example, when you type a website address into your browser, the browser uses the TCP/IP protocol to connect to the website’s server. Once connected, the browser sends a request for the web page, which the server then sends back to the browser. The browser then displays the page on your screen.
TCP/IP stands for Transmission Control Protocol/Internet Protocol. It is a set of communication protocols used for connecting computers on the Internet. TCP/IP is the language computers use to communicate with each other over the Internet.
Example: When you type in a website address in your browser, your computer sends a message to the web server using TCP/IP. The web server then responds with the requested web page, also using TCP/IP.
