HTTP (HyperText Transfer Protocol) - HTTP is a protocol for fetching resources such as HTML documents. It is the foundation of any data exchange on the Web and it is a client-server protocol.
HTTP/3 - HTTP/3 is the next major revision of the HTTP. It runs on QUIC, a new transport protocol designed for mobile-heavy internet usage. It relies on UDP instead of TCP, which enables faster web page responsiveness. VR applications demand more bandwidth to render intricate details of a virtual scene and will likely benefit from migrating to HTTP/3 powered by QUIC.
HTTPS (HyperText Transfer Protocol Secure) - HTTPS extends HTTP and uses encryption for secure communications.
WebSocket - WebSocket is a protocol that provides full-duplex communications over TCP. Clients establish WebSockets to receive real-time updates from the back-end services. Unlike REST, which always “pulls” data, WebSocket enables data to be “pushed”. Applications, like online gaming, stock trading, and messaging apps leverage WebSocket for real-time communication.
TCP (Transmission Control Protocol) - TCP is is designed to send packets across the internet and ensure the successful delivery of data and messages over networks. Many application-layer protocols build on top of TCP.
UDP (User Datagram Protocol) - UDP sends packets directly to a target computer, without establishing a connection first. UDP is commonly used in time-sensitive communications where occasionally dropping packets is better than waiting. Voice and video traffic are often sent using this protocol.
SMTP (Simple Mail Transfer Protocol) - SMTP is a standard protocol to transfer electronic mail from one user to another.
FTP (File Transfer Protocol) - FTP is used to transfer computer files between client and server. It has separate connections for the control channel and data channel.
