What is a Router?
A router is similar to a switch, but it performs a number of useful networking functions:
- It allows you to create a home network (like a switch), but a router actually separates networks allowing you to share your Internet access without being dependent on one computer's connection (unlike a switch).
- You can plug a printer directly into some routers, allowing printer access to any computer on the network.
- It provides built-in firewall capabilities that do not hinder network performance.
- You can share your broadband connection without purchasing additional IP addresses. (Check to see if your provider allows this.)
You can also get a wireless router. It performs many of the same functions, but allows you to combine a regular network with a wireless network.
