OSI (Open Systems Interconnection) reference model
[post_ad]
This lesson is an introduction to OSI (Open Systems Interconnection) reference model. In this lesson I explain the reasons of the emergence of OSI model as well as its benefits and advantages. To understand how data is transferred from computer to another, it is required that you study OSI model along with its layers. The lesson uses examples from everyday life to avoid vagueness in understanding and also to inculcate the stages of data transmission in students' minds. Moreover, the lesson gives a brief statement of the functions of each layer which will minutely be expounded in the following lessons.
