What Is The OSI Model? (Tech Lesson)
What Is The OSI Model? Here at CyberFreakz, we like to educate as well as inform. Today, we will be discussing the OSI model. The OSI (Open Systems Interconnection) model is a conceptual framework that defines how data is transmitted over a network. It is a seven-layer model that was created in 1984 by the International Organization for Standardization (ISO) to facilitate communication between different computer systems. In this blog, we will go over each layer of the OSI model and explain their functions. Layer 1 - Physical Layer : The physical layer is the first layer of the OSI model. It is responsible for the physical transmission of data over a network. This layer defines the physical characteristics of the network, such as the cable types, connectors, and transmission rates. It also defines the way that data is represented and transmitted over the network. Layer 2 - Data Link Layer : The data link layer is responsible for the reliable transmission of data between two devices.
