Top 8 Popular Network Protocols???

The internet runs on protocols.

Every time you open a website, send an email, join a video call, or upload a file — different network protocols are working behind the scenes.

This visual breaks down 8 essential protocols engineers should understand:

• HTTP / HTTPS – web communication
• HTTP/3 (QUIC) – faster modern web transport
• WebSocket – real-time communication
• TCP – reliable data transport
• UDP – fast connectionless communication
• SMTP – sending emails
• FTP – file transfer

Understanding these protocols helps you design better backend systems, APIs, and distributed applications.

The internet isn't magic.
It's protocols.
