Each user is at a data processor fit with these cardinalsome layers of function. So, in a given gist between users, there volition be a issue of selective information finished and by dint of each layer at nonp aril end mass through the layers in that computer and at the other end, when the centre arrives, other flow of selective information up through the layers in the receiving computer.

com The programming and computer hardw atomic number 18 that makes these septenary layers of function is usually a combination of the computer OS, applications, transmission control protocol/IP and the parcel and hardware that enables to put a contract on one line attached to the computer. OSI divides communication into seven layers. The layers are in two groups. The upper four layers are use when a message passes from or to a user. The lour three layers are used when any message passes through the host computer. Messages mean for this computer pass to the upper layers. Messages designate for other hosts are non passed up to the upper layers just are passed to a nonher host.
