Besides the standards that are common to all computer operating systems (like TCP/IP and IEEE 802.11), there are standards that are specific to Unix, POSIX, and Linux systems.
Obviously, Linux has standards that it follows. Standards, protocols, and other specifications make programming and telecommunications easy, predictable, compatible, and universal. Also, standards ensure compatibility and a common framework for developers to use. Computer and communication systems require standards and protocols to ensure that systems using such standards can efficiently and effectively communicate with one another.
