What Are Hub, Switch, Router, and Modem?
In today's digital age, networking has become an integral part of our daily lives. Whether it's at home, in the office, or on the go, we rely on networks to connect us to the world around us. To establish and maintain these connections, various networking devices are used, including hubs, switches, routers, and modems. In this article, we will discuss each of these devices, their functions, and how they differ from one another.
Hubs
A hub is the simplest type of networking device, and it is typically used to connect multiple devices to a network. Hubs operate at the physical layer of the OSI model, which means they simply repeat incoming network traffic to all connected devices, regardless of whether or not the devices need the information. Because of this, hubs are not very efficient and can lead to network congestion.
