QUIC
QUIC
A communication protocol designed to make data exchange on the internet faster and more reliable.
In Simple Terms
QUIC is a technology that reduces the waiting time when browsing websites on a smartphone or computer. It streamlines the setup process when starting a connection, allowing data to be exchanged right away. For example, when streaming a video in an area with an unstable signal, QUIC can maintain the connection even if it temporarily drops. It is used throughout the internet to speed up website loading and make apps run more smoothly.
Behind the Name
QUIC is simply the name of the protocol itself. While it was once described as standing for 'Quick UDP Internet Connections,' it is officially defined as a standalone name — 'QUIC' — rather than an acronym. Google originally developed it with the goal of making internet connections literally 'quick,' and it has since become a widely adopted international standard.
Take a Closer Look!
QUIC is a communication protocol designed to transport data efficiently over the internet.
It was built to address the limitations of the traditional TCP standard, enabling faster and more secure communication.
In simple terms, one of its defining features is reducing the overhead of the 'handshake' that takes place before a connection is established.
With older methods, multiple back-and-forth exchanges were required before any data could be sent — but with QUIC, that setup can be completed in a single round trip.
QUIC also recovers very quickly when a connection is interrupted.
Even if a smartphone switches from Wi-Fi to a mobile network while on the move, QUIC helps keep videos and websites loading without interruption.
Another key point is that encryption is built in from the start, protecting the contents of the connection by default.
Because it improves both speed and security at the same time, QUIC serves as the foundation of the HTTP/3 standard and is widely used across the internet.
