Network equipment refers to the hardware devices that facilitate communication and data transfer within a computer network. Common types of network equipment include routers, switches, hubs, and modems. These devices help connect computers and other devices, allowing them to share resources and access the internet. Each piece of network equipment plays a specific role. For example, routers direct data traffic between different networks, while switches connect devices within the same network, ensuring efficient data flow. Modems convert digital signals to analog for internet access, making them essential for connecting to service providers.
