A communication protocol is a set of rules for exchanging info over a network. In a protocol stack (additionally see the OSI mannequin ), each protocol leverages the companies of the protocol layer below it, till the lowest layer controls the hardware which sends info across the media. The use of protocol layering is at this time ubiquitous across the sphere of computer networking. An vital example of a protocol stack is HTTP (the World Wide Web protocol) operating over TCP over IP (the Internet protocols ) over IEEE 802.eleven (the Wi-Fi protocol). This stack is used between the wireless router and the home user’s personal computer when the consumer is surfing the online.
