1. OSI Model stands for Open System interconnection model. 2. OSI Model defines how data is transferred from one computer to another computer. 3. In a very basic scenario two computers connected with a LAN and connectors transfer data using the NIC. This forms a computer network, however if both the system uses different operating systems, for example one system runs on windows and other one runs on MacOS then how can data be transferred between these two different systems, here comes the role of a OSI model which is a seven layered model that defines how a data can be transferred between different systems. 4. OSI model was introduced by International Organisation for standardisation (ISO) in 1984. 5. There are seven layers in a OSI model Application layer Presentation Layer Session layer Transport layer Network Layer DataLink layer Physical layer Physical Layer We now learned that a transport layer converts the data into segments, network...
