First I am talking about virtual ports and not the physical ports. Virtual Ports are those which allow transfer of data just like physical ports but the only thing is they are virtual ie you can’t see them, they just reside in your PC.

In computer networking, a port is an application-specific or process-specific software construct serving as a communications endpoint used by Transport Layer protocols of the Internet Protocol Suite, such as Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). A specific port is identified by its number, commonly known as the port number, the IP address it is associated with, and the protocol used for communication. – Wikipedia

As I said these ports are used to transfer data mainly, but since you can’t see them you aren’t aware which posts are open. For eg if you are using http or in simple language if you are using internet for surfing websites than your port 80 is opened.

But what’s in it? What will happen if I let my ports open? Before answering that note this – some posts are meant to be opened for eg Port 80 for Http and Port 25  for sending and receiving mail etc, but not all. A Hacker may open some of your closed port and initiate data transfer without letting you know. So if you ever get a warning bu your AntiVirus or want to see which all ports are open than you can head up to canyouseeme.org

This page will serve as a free utility for remotely verifying a port is open or closed. It will be useful for users who wish to check to see if a server is running or a firewall or ISP is blocking certain ports. But to check the ports first you need to know thw port no and this List will help you.
