Exam MTCNA Topic 9 Question 110 Discussion

The OSI (Open Systems Interconnection) model is a conceptual framework that standardizes the functions of a communication system into seven distinct layers. It is used to understand and design computer networking systems.
The seven layers of the OSI model are:
* Application
* Presentation
* Session
* Transport
* Network
* Data Link
* Physical
Each layer has its own specific purpose and interacts with adjacent layers to perform data transmission functions.
MTCNA Official Course Material - OSI Model Chapter:
"The OSI model consists of 7 layers. Understanding these layers is critical for troubleshooting and protocol analysis." Rene Meneses MTCNA Study Guide - OSI Model Section:
"There are exactly seven OSI layers. They range from the Physical Layer (Layer 1) to the Application Layer (Layer 7)." Terry Combs Notes - OSI Summary Page:
"OSI = 7 Layers. The most important ones for network engineers are Layer 1 through Layer 4."
