Before moving to our topic open systems interconnect model (osi), we will gain some information about the internet osi model - brief introduction in the beginning, when people were creating the network, there were no rules regarding interconnecting each network. The osi model (open system interconnect) is a theoretical stack of 7 layers that can be used as a reference to the open systems interconnection (osi) model is a 7-layer data model that very simply describes the software protocols and hardware involved in end-to-end.
