Ports Before we begin here are what I chosen. I chose to go with that are considered beginner to the intermediate stages of IT. They are as follows.
Port 22 - SSH (Secure Shell):
A standard for secure remote login and network services. Understanding SSH is crucial for secure administration of servers and network devices.
Port 80 - HTTP (Hypertext Transfer Protocol):

Port 443 - HTTPS (HTTP Secure):

Port 53 - DNS (Domain Name System):
Crucial for understanding how domain names are resolved into IP addresses, which
is a foundational aspect of internet navigation and networking.
Port 25 - SMTP (Simple Mail Transfer Protocol):
