What is OSI and what role does it play in computer networks?

OSI model stands for Open Systems Interconnection. Basically it is used for making users understand the concept of networking. This series of actions are defined into different layers which from the basis of OSI model. Each layer has a predefined set of functions and all layers are responsible for the complete process.

How does the OSI model work in the real world?

Conversion of data from one format to another is the job of the PRESENTATION layer. A web browser can convert these file formats into the local formats used on the local computer for displaying images, playing sounds and displaying text; if it cannot, it often can launch an application which does understand the format.

What are the benefits of using the OSI model?

The advantages of the OSI model are

• It is a generic model and acts as a guidance tool to develop any network model.
• It is a layered model.
• It distinctly separates services, interfaces, and protocols.
• It supports both connection-oriented services and connectionless services.

What is OSI model and TCP IP model?

OSI model is a generic model that is based upon functionalities of each layer. TCP/IP model is a protocol-oriented standard. OSI model gives guidelines on how communication needs to be done, while TCP/IP protocols layout standards on which the Internet was developed. So, TCP/IP is a more practical model.

What is OSI model in computer networking PDF?

The concept of computer networking is simplified by a standardized classification model called the Operating System Interconnection i.e. OSI Model. The OSI Model breaks down each of the conceptually similar functions into a framework of seven layers where each layer can communicate with the layer adjacent to it.

What is the role of OSI layers when we open a webpage?

Originally Answered: What is the role of OSI layers when we open a webpage? These layers are part of networking stack provided by the OS. When you make an HTTP request – ultimately this is meant to be sent to a Web Server. Since HTTP works at Application Layer.
