My LAN Diagram

First Diagram

I try to design this diagram and I so proud to made this because I did not have basic in LAN design, I just learn by my self and I read in the manual.

So. I do not know is this right diagram..

Ini adalah gambar perdana saya belajar menggunakan Offiece Visio.. entahlah apakah ini bagus apa nggak, tapi menurutku lumayan.
