Networking devices are hardware components that facilitate communication between computers and other devices within a network. Common examples include routers, switches, and hubs. These devices help manage data traffic, ensuring that information is sent to the correct destination efficiently. Routers connect different networks, allowing data to flow between them, while switches connect multiple devices within the same network, directing data to the appropriate device. Hubs serve a similar purpose but are less efficient, broadcasting data to all connected devices. Together, these devices form the backbone of modern communication systems.
