In the 7-layerOSI model(see below), the network layer is layer 3. TheInternet Protocol (IP)is one of the main protocols used at this layer, along with several other protocols forrouting, testing, andencryption. Suppose Bob and Alice are connected to the same local area network (LAN), ...
OSI is a communications reference model to help conceptualize how data can be transmitted and received on a network. The model consists of seven distinct layers forming astack. Each layer in the stack is performed in a step-by-step manner: first, moving up the stack during data transmissions ...
The application layer is the seventh layer in the OSI model. Though the name might be deceiving, it’s not an actual application; rather, it’s a component within an application that manipulates information. It’s essentially designed to provide network services to the end user. Users can tra...
The network layer is layer 3 in the Open Systems Interconnection model or OSI model. It describes protocols used to route traffic within or across multiple networks. Furthermore, Routers are a key piece of networking hardware that implements this packet routing in the real world. The network lay...
The modern Internet is not based on OSI, but on the simpler TCP/IP model. However, the OSI 7-layer model is still widely used, as it helps visualize and communicate how networks operate. Why Is the OSI Model Important? The OSI model provides several advantages for organizations managing net...

In the following section, we will delve into each layer of the OSI Model, providing detailed insights into their functions, protocols, and contributions to the seamless operation of network communication. Layer 1: Physical Layer The Physical Layer serves as the foundation of the OSI Model, ...
The Open Systems Interconnection (OSI) model is a conceptual model that divides network communication and interoperability into seven abstract layers.
In the OSI model, the transport layer is positioned between the session layer and the network layer. This means, then, that the layer fundamentally makes sure that the anticipated message is supplied. What does the transport layer do? In computing networking, OSI model layer 4 provides a lot...
OSI Model in the Real World While conceptual in nature, the OSI model can come in handy on the job. If there's an issue with a network, having a visual map of what's occurring can help IT pros narrow down the problem. For example, is it a physical layer or an application layer is...
