Info You Need About Routers for A+ Exams
If you’re pursuing your compTIA A+ Certification, you need to know about the hardware devices involved in setting up a network. One of the devices that might appear on the exams is a router.

When a computer on your network wants to send information to a computer on another network, your computer passes the information to your router.
