TCP, or Transmission Control Protocol, is connection-oriented, meaning it establishes a formal handshake before transmitting data and ensures packets arrive in order and without errors. Commonly Used Port Numbers and Their Roles Certain tcp udp port numbers have been standardized by the Internet Assigned Numbers Authority (IANA) to ensure global consistency.

This prevents conflicts and allows multiple simultaneous connections on the same machine. Security policies must explicitly define which ports are open to the internet and which are closed to prevent unauthorized access.
In contrast, UDP is preferred for scenarios where speed matters more than perfection, such as live video streaming, online gaming, and Voice over IP (VoIP), where a dropped packet is preferable to a delayed one. Port Number Protocol Service / Description 80 TCP HTTP (Unencrypted Web Traffic) 443 TCP HTTPS (Encrypted Web Traffic) 22 TCP SSH (Secure Shell Access) 53 TCP/UDP DNS (Domain Name System) 25 TCP SMTP (Email Transmission) Dynamic and Private Ranges Above the well-known ports, the range from 1024 to 49151 is registered for user applications or dynamic assignment.

The Core Difference Between TCP and UDP The primary distinction between TCP and UDP dictates how these port numbers are utilized in practice. These well-known ports, ranging from 0 to 1023, are reserved for specific system or network services.
