An internet router is a device that connects your devices to the internet and creates a local area network (LAN). It receives data from your modem and sends it to your devices, such as computers, phones, and tablets. 

A router acts like a dispatcher, choosing the best route for your data to travel. It can also:

• • Protect your network: A router can act as a firewall to protect your network from outside threats. It can also hide the IP addresses of your devices from the public internet.
  • Set parental controls: You can use a router to restrict internet access for certain devices.
  • Connect to a VPN: A router can connect to a virtual private network (VPN) to provide additional security and privacy.
