the first two layers of OSI model i.e. physical layer & data link layer are involved in hard ware installation.
The physical and link layers (layers 1 and 2) are implemented in hardware. The remaining five layers use these two layers to communicate across a network, and are done by software.
OSI
an upper-layer, connection-oriented protocol or service
The OSI Model stands for Open Systems Interconnection. The answer to the question which layer of the OSI model are layers capable of functioning is at all layers.
no its is not implemented right now its just conceptual
The benefits of following the OSI model are as follows: * Any hardware that meets the OSI standard will be able to communicate with any other hardware that also meets the standard * Any software that meets the OSI standard will be able to communicate with any other hardware or software that also meets the standard * Consumers are given a wider choice since hardware/software from any manufacturer will work together * OSI is independent of country, it doesn't matter where the hardware/software is made * OSi is not dependent on the operating system used * The Protocols for OSI are defined at each stage * Any errors that occur are handled in each layer * The different layers can operate automatically Why is it important to have standards for communicating? * To enable devices to communicate together * To allow devices to be guaranteed as reliable * To allow purchasers to know the device will work How does the OSI model assist in the introduction and maintenance of standards? * It is an agreed standard that has world wide recognition * Use of the standard ensures compatibility * Purchasers recognize what the standard means and the guarantees that come with it
