When it comes to hacking, knowledge is power, the more you know, the more options you have to attack, making critical a proper enumeration before any type of exploitation.

Before attacking our target we need to know what is what we are about to attack, we need to know what type of services or OS is running, and we can accomplish that by making a network map, hence the name of Nmap, specifically doing “port scanning”, because these services are listening on a specific “ports” of the network, being ports a network structure your service runs on to establish a connection, the service are always “listening” (waiting for another device that wants to establish a connection) and the user when connecting to the specific port they open a port for receiving information from the other port (for example: HTTPS 443)
