It consists of seven layers, each of which performs a specific function in the communication process. The layers are organized in a hierarchical structure, with each layer relying on the services ...

The Physical Layer includes cable specs, pin-out patterns, voltages, hubs, repeaters, network cards, protocol standards (RJ45, V series modem standards) and even host bus adapters (HBA).

The layers, and what they represent, are as follows: Layer 7: Application. The Application Layer in the OSI model is the layer that is the “closest to the end user”.

The OSI model defines protocols for how a network technically handles communications at the various functional layers. Starting with electrons and photons at the physical layer (Layer 1), the ...

A couple posts ago, we talked about Layer 1 of the OSI Model — the Physical Layer. Today, we’ll start our climb up the Model with a visit to Layer 2, the Data Link Layer .
