OSI model
The OSI means open system interconnection model is conceptual and logical layout that defines network communication used by systems open to interconnection and communicate with other system.
It defines logical network and effectively describes computer packet transfer by using different layer protocol . the OSI model was developed by the international for standardization (ISO) in 1978.
The ISO was a committee different vendors system. The ISO was a committee represented by many different organizations whose goal was not to favor a specific method of communication but rather to develop a set of guidelines that would allow vendors to ensure that their products would inter-operate
Moreover, the OSI model was created to simplify communications between system. There are many events that need to take place in order to ensure that data first reaches the correct system and is then passed along to the correct application in a usable format. A set of rules was required to break down the communication process into a simple set of building blocks.
