Demystifying Ports: Understanding Logical Connections in Computer Networks

🔌Ports are not physical connections but rather logical connections used for exchanging information.

🌐Ports have unique numbers from 0-65535 and are associated with specific programs or services on a computer or server.

🔎IP addresses determine the geographical location of a server, while port numbers determine which program or service on that server is used.

💻Port 80 and 443 are commonly used for web pages, port 21 for FTP, and port 25 for email.

🌍Port numbers range from 0-65535, with well-known ports (0-1023), registered ports (1024-49151), and dynamic/private ports (49152-65535).
