Definition OSI Layer along with usability and how to work OSI Layer

In the old days before the creation of OSI, doing a communication on the computer network is not easy because each vendor and developer at that time use their respective network protocols, thus complicating users when going Exchanging data from a computer with another computer due to the network protocols that each computer has different.

Seeing this, in the year 1980-an international standardization agency, the International Organization for Standardization (ISO) created a reference model called OSI consisting of seven layers.

Each layer has its own role so that at this time we do not have to worry about the problem of computer protocols what you will use to be able to communicate with your friends. For more clarity on the definition of OSI layer or OSI model, seven layers and how it works, see the explanation below.

Definition of OSI Layer (OSI Model)
Open System Interconnection or commonly abbreviated OSI is a reference model in the form of a conceptual framework that defines the standard of connection for a computer.

The purpose of this OSI reference model is to be a referral for vendors and developers so that the products or software they make can be interporate, which means it can cooperate with other systems or products without having to Make special efforts from the user.
