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 […]
The Physical Layer is the first and lowest layer in the OSI (Open Systems Interconnection) model and is responsible for the actual physical transmission of data over a network medium. It deals with the hardware aspects of network communication and provides the means to transmit raw bits over the physical medium. Here are the key […]
The OSI (Open Systems Interconnection) model is a conceptual framework that standardizes the functions and processes of computer networks and data communication into seven distinct layers. Each layer in the model performs specific tasks and interacts with adjacent layers, creating a hierarchy of network-related functions. The OSI model is used as a reference point to […]
