This figure shows the logical network flow from student’s home network to UTeM campus network. A student is trying to access the Ulearn system located in UTeM network facilities. In this article, we are going to see how data travels from student’s computer to reach the Ulearn system server using OSI Model. What is OSI Model? Open System Interconnection (OSI) Model is a conceptual framework that describe the working of networking system. It is a 7 layered architecture where each layer perform different functionality in the communication system. The seven layers are: Physical Layer Data Link Layer Network Layer Transport Layer Session Layer Presentation Layer Application Layer The travel of data from student’s computer to reach the Ulearn system server is as below: Application Layer (Layer 7) The application layer is responsible for providing services to user. It provides services for network applications with the help of protocols which allows the student to acces
