ISO-OSI Model Basics Flashcards
Purpose of the ISO-OSI model Layers of the OSI model Functions of specific layers (Physical, Network, Application, etc.)
What is the primary purpose of the ISO-OSI model?
It gives a standard to how different networks devices communicate among each other.
Which layer of the ISO-OSI model is responsible for determining the best path for data to travel?
Network
What is the primary purpose of the ISO-OSI model?
The ISO-OSI model standardizes network communication by dividing it into 7 layers. This ensures that devices and protocols from different manufacturers can work together smoothly.
Name the seven layers of the ISO-OSI model in order from Layer 1 to Layer 7.
Physical, Data Link, Network, Transport, Session, Presentation, Application
What is the role of the Physical layer (Layer 1) in the ISO-OSI model?
The Physical layer is responsible for the actual transmission of raw data over physical hardware such as cables, fiber optics, or radio signals.
What does the Network layer (Layer 3) handle in the ISO-OSI model?
The Network layer manages logical addressing and routing. It determines the best path for data to travel across different networks.
What is the function of the Application layer (Layer 7) in the ISO-OSI model?
The Application layer provides network services to the end-user and directly interfaces with software applications like web browsers and email clients.
Meaning of ISO-OSI
ISO-OSI stands for International Organization for Standardization - Open Systems Interconnection. It’s a model that helps different devices and networks talk to each other by breaking the communication process into seven layers, like steps in a chain. Each layer has a specific job, making sure data gets from one device to another without issues, even if the devices are from different companies.
