Data Communication and Networking
Video Presentation OSI Layer model and Network Component The Open Systems Interconnection (OSI) model was first introduced in the late 1970s by International Standards Organization (ISO), it is a standard that covers all aspects of network communications. The OSI model is a reference model that describes how information from a software application in one computer moves through a physical medium to the software application in the other computer. The OSI model consists of seven separated but related layers, each of which defines a part of the process of moving information across a network. The seven layers from top-down are: 1. Application Layer 2. Presentation Layer 3. Session Layer 4. Transport Layer 5. Network Layer 6. Data Link Layer 7. Physical Layer Based on the scenario, the data will travels from student's computer using their home network to reach the Online Learning system located in OUM network facilities. We will explain the details on how the data flow based
