The section also discusses the two principles upon which the protocol layering is based. The first principle dictates that each layer needs to have two opposite tasks. The second principle dictates

The Elements of Communication * The first of these elements is the message source‚ or sender. Message sources are people‚ or electronic devices‚ that need to send a message to other individuals or devices. * The second element of communication is the destination‚ or receiver‚ of the message. The destination receives the message and interprets it. * A third element‚ called a channel‚ consists of the media that provides the pathway over which the message can travel from source to destination

explained with all layers as well as their responsibilities. Open Systems Interconnection model (OSI model): OSI reference model is now considered as a primary standard for internetworking and inter computing. Today many network communication protocols are based on the standards of OSI model. In the OSI model the network/data communication is defined into seven layers. These 7 layers further divide the tasks of moving the data across the network into subtask and hence complete one communication

It would manage their use of the network and keep them focused on their work. These are just several examples of the Session layer of the OSI Model in action. The OSI model interacts with protocols that correspond with each layer and help regulate and manage the network communications. There are many protocols which work

and each vendor had its own standards and protocol? What impact would this have on your personal life or business communications? If each vendor had their own standards and protocols‚ we would have a harder time making devices that we use every day to inter-operate. Imagine buying specific BRAND of ROUTER for a SPECIFIC computer just to use the internet; so if you have a Sony computer you would also need a Sony wireless router to connect to the internet via provided Sony made routers. We would

extensible‚ flexible‚ and scalable. As a result‚ the WAP protocol stack is divided into five layers: 1) Application Layer - Wireless Application Environment (WAE). This layer is of most interest to content developers because it contains‚ among other things‚ device specifications and the content development programming languages‚ WML and WMLScript.
