Study Notes
WebSockets
- The primary purpose of a WebSocket is to enable bidirectional, real-time communication between a client and a server over the web.
WebSocket vs HTTP
- WebSockets differ from HTTP in terms of message exchange, as they allow for bi-directional, continuous communication, whereas HTTP uses a request-response model.
WebSocket Handshake
- The WebSocket handshake process is significant as it establishes a connection between the client and server, allowing for subsequent bi-directional communication.
QUIC vs TCP
- QUIC (Quick UDP Internet Connections) differs from TCP (Transmission Control Protocol) in terms of latency, packet loss control, and evolvability, making it a more efficient and secure protocol.
WebSocket Advantages
- The main advantage of WebSocket for collaborative applications like Google Docs is that it enables real-time, bi-directional communication, allowing for seamless collaboration and live updates.
WebSocket vs Traditional Sockets
- WebSockets differ from traditional sockets in terms of communication, as they are designed for bidirectional, real-time communication over the web, whereas traditional sockets are used for general-purpose communication.
Transport Layer Protocols
- TCP (Transmission Control Protocol) is a transport layer protocol that requires an established connection to transmit data and has extensive error checking and acknowledgment of data.
- UDP (User Datagram Protocol) is a transport layer protocol that is connectionless and does not guarantee delivery of data to the destination.
- QUIC (Quick UDP Internet Connections) is a transport layer protocol designed to reduce latency, has improved packet loss control, and is built on top of UDP.
- QUIC is designed to make the web faster, more efficient, and more secure, and is evolvable unlike UDP and TCP.
QUIC Ecosystem
- The Google ecosystem currently supports QUIC and uses it by default instead of TCP.
QUIC Handshake
- QUIC does not require a 3-way handshake like TCP and exchanges security keys as part of the initial handshake process.
TCP
- TCP is a connection-oriented Internet protocol with error-checking and recovery services, and is instinctively reliable, guaranteeing data will be delivered in the order it was sent.
