Well I have a Windows machine and also a Ubuntu laptop, my Ubuntu laptop can see everything in the network, but Windows cannot see Ubuntu. Please remember that I am an absolute beginner to Networking and Ubuntu, so keep it simple! Thanks in advance.
If I remember correctly, Windows does not(I don't want to use the incorrect technical terminology) recognize the format of the Linux OS, but Linux did program their OS to recognize Windows(ntfs). However you could write a text document with a Linux text application, and Windows would be able to open it with Notepad. For the most part you can open, not everything, but Linux is way more flexible toward Windows. I hope that helps.
