In the OSI model, what is the main purpose of a Layer 3 device?
Networking Model
Networking is a method of linking two or more devices in order to share data, give technical support, and communicate. It refers to the communication between connected computing devices such as desktops, laptops, smartphones, servers, and tablets and also Internet of Things (IoT) devices such as cameras, doorbells, door locks, and various sensors.
Design of the Network System
For a medium and a large scale business around the globe computers and networking plays a major role. With the access of these digital components hardware, all the necessities are interconnected and thus business runs smoothly. As the daily consumption rate of a product is increasing day by day thus the networking factor or the network design of a business is also becoming more complex.
Networking
Networking refers to the communication shared between a group of computers. A group of computers connected to each other for the purpose of sharing resources and information is called a computer network. The first computer network was ARPANET, which stands for Advanced Research Projects Agency Network.
In the OSI model, what is the main purpose of a Layer 3 device?
In the OSI (Open Systems Interconnection) model, Layer 3 is the Network Layer. The main purpose of a Layer 3 device is to provide network routing and logical addressing within a network. Layer 3 devices are responsible for forwarding data packets between different networks, and they play a critical role in determining the best path for data to travel from a source to a destination across interconnected networks.
