By using it. Many Linux distributions are designed to cater especially to new users. Classic Unix is abit harder to learn, but Solaris has a decently friendly user interface, if you can get past the god-awful installer.
Unix and windows are two separate groups of operating systems. Windows is the operating system of about 90% of personal computers, while unix is the basis of many other operating systems, such as Mac OS X
Ubuntu seems to be the easiest if you are looking for something that "just works" and you want to learn on it as well. If you are looking for a real learning experience try one of the more advanced distros like Slackware or Linux From Scratch. Either way, your distro doesn't matter as much as you would think once you get under the hood.
There is very little difference in the C compiler between Unix and Linux; in some cases (the gcc compiler) it is the same. The differences come in when using system calls; some system calls do not exist in Unix or Linux, although most do. The program I work on compiles the same way (for the most part) between all commercial versions of Unix and several variants of Linux. In other words, the code is fairly portable across platforms.

The easiest way is to use the "networkmanager" applet. In kde it is called "knetworkmanager".
"Linux" as a operating system distribution (which includes the kernel as created by Linus Torvalds), was in some way influenced by Unix (this includes Apple's Mac OS and OS X, which was based on BSD, which was derived from Unix) at some point in their development.
Depends on how you learn, I find repetition easiest
Learn to play Christian music
The easiest way would be: cat file1 > file2
I would say that the easiest way to learn sign language is to go to your local library, get some books on sign language, and study up!
Type to learn 3 it helped me a lot
the easiest way to learn more is to listen more and if your in the back of the room ask to be in the front so you learn more.
