Networking capabilities include support for the major protocols and services, as well as enhanced features provided by Mac OS X. Developers can use the networking APIs to provide sophisticated LAN, WAN, Internet, and web capabilities in Cocoa applications. These are accessible through sockets and Core Foundation, as well as through the higher-level Cocoa APIs.
