In order to make it easier for most, there is a movie file available which will show your exactly what we are about to analyse. 2018-08-22 2020-05-01 Networking is a vast topic. The OSI model helps us better understand it. In this article, we will cover the OSI model. The Open Systems Interconnection (OSI) model is a conceptual framework that describes the functions of a networking or telecommunication system in seven layers..

Advanced Data Center Switching (ADCX) En attack mot ett datasystem i syfte att hindra normal användning av systemet. The Open Systems Interconnection model (OSI model) is a conceptual model  av D Wildmark — and the TCP/IP model are similar to each other, and a comparison can be seen in table 1. OSI Model. TCP/IP Model.

The main function of the data-link layer is to perform error detection and combine the data bits into frames. It combines the raw data into bytes and bytes to frames and transmits the data packet to the network layer of the desired destination host.

It is a 7 layer architecture with each layer having specific functionality to perform. All these 7 layers work collaboratively to transmit the data from one person to another across the globe. When the data are sent across networks, and reach the receiving computer, they will be sent up from the bottom of the OSI model (decoding process), and are displayed to the end user. The OSI Model Layered Architecture :- The seven layers can be thought of as belonging to three subgroups. Layers 1,2 and 3- physical, data link and network are the network support layers; they deal with the physical aspect of moving data from one device to another.
