8 Popular Network Protocols in 1 Diagram
Network protocols are standard methods of transferring data between two computers in a network.
1. HTTP (HyperText Transfer Protocol)
HTTP is the fundamental protocol that enables all communication on the World Wide Web. It allows web browsers to request documents, images, videos and other resources from web servers.
2. HTTP/3
HTTP/3 is the next major iteration of HTTP, providing faster page loads by running on the QUIC protocol instead of TCP. It's optimized for modern mobile internet usage.
3. HTTPS (HyperText Transfer Protocol Secure)
HTTPS secures HTTP web requests through SSL/TLS encryption. This is critical for protecting sensitive information like financial and personal data transmitted online.
4. WebSocket
WebSocket enables persistent, low-latency real-time communication between clients and servers - ideal for applications like messaging, gaming and stock trading that require constant data streams.
5. TCP (Transmission Control Protocol)
TCP guarantees reliable end-to-end data delivery through sequence numbers, acknowledgments and automatic retransmissions. It ensures complete transfer of data despite network interruptions. Many application-layer protocols build on top of TCP.
6. UDP (User Datagram Protocol)
UDP focuses on sheer speed rather than reliability, blasting video, voice and game data across networks without guaranteed delivery checks. Packets may arrive out of order or go missing altogether.
7. SMTP (Simple Mail Transfer Protocol)
SMTP is the standard that enables routing and transferring of email messages between mail servers, services and clients.
8. FTP (File Transfer Protocol)
FTP allows simple, efficient transfer of files between network devices. Though aging, it's still widely used by services offering file downloads and storage.
