How is the OSI model used in networking?

The OSI Model (Open Systems Interconnection Model) is a conceptual framework used to describe the functions of a networking system. The OSI model characterizes computing functions into a universal set of rules and requirements in order to support interoperability between different products and software.

How does the OSI model work and include an example?

The Physical layer of the OSI model is responsible for the transfer of bits — the 1’s and 0’s which make up all computer code. This layer represents the physical medium which is carrying the traffic between two nodes. An example would be your Ethernet cable or Serial Cable.

What is the OSI model Why is it important for understanding networking?

The OSI model acts as a roadmap of what is happening within a network and helps to see how information is transferred across a network. In this article, we’re going to look at what the OSI model is. The OSI model has proved itself a worthy blueprint for network administrators since its creation in 1984.

Why is routing the responsibility of the network layer?

The network layer is responsible for routing, which is moving packets (the fundamental unit of data transport on modern computer networks) across the network using the most appropriate paths. It also addresses messages and translates logical addresses (i.e., IP addresses) into physical addresses (i.e., MAC addresses).

Which layers of the OSI model are the network support layers and user support layers?

Transport layers has the network support layer and the user support layer.

  • The transport layer is the layer in the open system interconnection (OSI) model responsible for end-to-end communication over a network.

    • Which layers are not network support layers?
