The Session Layer, also known as Layer 5 in the OSI (Open Systems Interconnection) model, is responsible for managing sessions or connections between devices on a network. It provides services that allow applications to establish, maintain, and terminate communication sessions. Here are the key characteristics and functions of the Session Layer: It’s important to note […]

The Transport Layer is the fourth layer in the OSI (Open Systems Interconnection) model, and it is responsible for end-to-end communication between two devices in a network. The Transport Layer ensures that data is delivered reliably, efficiently, and in the correct order. Here are the key characteristics and functions of the Transport Layer: The Transport […]

The Network Layer is the third layer in the OSI (Open Systems Interconnection) model, and it plays a crucial role in routing data packets from a source to a destination across multiple networks and devices. This layer is responsible for logical addressing, routing, and the establishment of end-to-end communication paths. Here are the key characteristics […]

The Data Link Layer is the (2nd) second layer referred to as layer 2 in the OSI (Open Systems Interconnection) model and is responsible for creating a reliable link between two directly connected nodes, typically over a shared medium. It manages the data link, ensuring the integrity of data transmission and controlling access to the […]
