Packet tracer
Lets play around with Packet tracer
This is a good network simulation for those who never been in with Cisco devices before. I have play with it for a number of times, and find it quite useful. I can suggest another one, where it is a network emulator (notice the difference?) which is more powerful and uses more processing and memories.
It is GNS3. It is more real-life comparing to Packet Tracer, but still we can learn something out of Packet Tracer. GNS3 is emulate the image of the device which is actually boots up the image and I heard we can even use it in LAN setup. How far we can use the feature is not known to me but I'm sure you can find out about it. Let's focus on the Packet Tracer.

You'll need to login for downloading it and get the latest version. If you have another way of obtaining it, be my guess.
Let's play around once install. I'll show you around in next post.
