How to kill a process which is using port 8080 in windows

A process is basically a copy of a program. So, if you run a program like Notepad multiple times, each specific time will get its own Process. A process uses resources, such as available RAM on your computer. If you look at Task Manager and you see the program running multiple times, each different occurrence of the program can be a different process.

The PID (“process ID”) numbers are assigned by the operating system each time a new process is made.

Port Number:

A port number is a way to identify a specific process to which an Internet or other network message is to be forwarded when it arrives at a server.A port number is the logical address of each application or process that helps in identifying the sender and receiver processes of messages.
