| The Network Port Scanner application identifies virtual network ports for a computer that are open to connection from another computer.
 
 A network port such as: 80 (http),
 443 (https), or 21 (ftp) are common ports.
 
 There are many reasons a network port would be open on a computer to allow access to an application or service.
 
 However, there are other times that having a 
						port open for when not necessary provides an opportunity 
						for a bad actor to be able to connect to a computer.
