QUICType
About
QUIC is a transport layer network protocol built on UDP that provides encrypted, low-latency data transfer, underpins 
HTTP/3, and was originally developed by Google.
It combines transport and security in a single protocol, establishes connections in as little as one round trip, supports multiple independent streams within a single connection to avoid blocking, and preserves sessions when a device changes IP address or network.
Transport Layer Security (TLS) is a cryptographic protocol that provides end-to-end encryption of data transmitted over the Internet, ensuring confidentiality, integrity, and authentication between communicating systems.
It is used in HTTPS to secure communication between browsers and servers, combining asymmetric cryptography for key exchange, symmetric encryption for data transfer, and digital certificates to verify server identity.
