Introduction of Socket/UDP protocol based on UDP Protocol/UDP protocol lookup dns/process Introduction/operating system and process history

Both TCP and UDP are port-based protocols. TCP has links, and UDP has no links. The TCP protocol also drops packets (network problems, the data may be gone)The application is sent to the operating system's cache, and the operating system is removed from the cache, and once the data is lost, it is completely gone. TCP is reliable because the data in its own cache is emptied after it receives a confirmation message.How UDP works I took it out of my own
