Multiple Choice

What is the main purpose of routers?

• Routers connect computers and choose the path that information takes from one computer to another.

• Routers connect computers to nearby wireless devices, such as headphones and speakers.

• Routers translate a website’s name into an IP address.

• Routers increase the speed of a network’s internet connection by decreasing the latency.
