I am currently running Knoppix on CD just learned that i cannot install new promgrams because it is a CD. well i went online looking for programs available to download for linux and went to Firefox. I went to go see how it would install and i saw a bunch of codes

Now my question is, when installing programs is it like windows and all i have to do is active the program and then it will install itself or do i need to learn about these codeS?
