About network ports
A network port is an endpoint that is allocated by the system to connect a specific application or service on a device to other devices/hosts (as well as with programs on the same device). Each unique port has its own number from 0 to 65535, which is transmitted across the network in the packet header along with the IP address. When establishing communication with a designated host, the app sends a request or waits for receiving data from a known port open on the device.
Why port scanning is important
Using an online scanner allows you to check the vulnerability of your device from the outside as it is "seen" by potential hackers and malware (viruses, Trojans).
