Today, although the underlying protocols used by the socket API have evolved over the years, and new ones have developed, the low-level API has remained the same. Client-server applications of all types and sizes came into widespread use. Web servers and browsers weren’t the only applications taking advantage of newly connected networks and using sockets. When the Internet took off in the 1990s with the World Wide Web, so did network programming. Their use originated with ARPANET in 1971 and later became an API in the Berkeley Software Distribution (BSD) operating system released in 1983 called Berkeley sockets.
