What's the difference between a hub, a switch, and a router?

What's the difference between a hub, a switch, and a router?

*

In a word, intelligence.

Hubs, switches, and routers are all devices that let you connect one or more computers to other computers, networked devices, or even other networks. Each has two or more connectors called ports into which you plug in the cables to make the connection. Varying degrees of magic happen inside the device and therein lies the difference. I often see the terms misused, so let's clarify what each one really means.

The Most Important Attitude

Lee Guptill writes:

Great pep-talk, Leo. I have to confess that I absolutely did not want a computer, and my husband MADE me get one around 7 years ago. Not only did my reluctance put my kids at an extreme disadvantage educationally (I did not realize it at the time--I thought computers were just plain evil), but I found that I was really missing out on life. I now have this all-consuming hobby that is computer based and brings me the greatest joy in my life (next to my husband and family). It would not be possible without the WWW. So thanks for the reminder that attitude is just everything. This article will be logged into my thankfulness journal today:)

Even Microsoft, internally, agrees. Despite the names the marketing department gave them, XP is Windows version 6.0, "Windows 7" is really Windows 6.1, and "Windows 8" is really Windows 6.2, making them "minor" version upgrades.
