A router is a device that connects two or more packet-switched networks. It is typically used to connect employees to networks, both local and the Internet, where just about every essential business activity takes place. Routers guide and direct network data, using packets that contain various kinds of data—such as files, communications, and simple transmissions like web interactions. Without routers, we wouldnt be able to use the Internet to collaborate, communicate, or gather information and learn.

A router is also used to provide security. Embedded firewall and content filtering software provide additional protection from unwanted content and malicious websites without affecting your online experience.

Most routers allow you to connect hard drives and use them as file-sharing servers, or printers that can then be accessed by anyone on the network. Routers can also broadcast a wireless signal (Wi-Fi) to connected and enabled devices, but they are not only for Wi-Fi. Routers also offer hard-wired connections to the Internet.

In summary, a router is used to:

• Connect employees to networks, both local and the Internet, where essential business activities take place.
• Guide and direct network data, using packets that contain various kinds of data.
• Provide security through embedded firewall and content filtering software.
• Allow you to connect hard drives and use them as file-sharing servers, or printers that can then be accessed by anyone on the network.
• Broadcast a wireless signal (Wi-Fi) to connected and enabled devices, and offer hard-wired connections to the Internet.
