GNU means? can u tell me brief info. about it?

Answer 1

@Jaque: You are confusing GNU and open source, I think. GNU is a set of open source utilities that make up the core of a Linux sys (file utilities etc), not necessarily the Linux kernel. There is a GNU kernel, true, but it's not yet production ready so the Linux kernel is used instead on Linux systems.

Answer 2

GNU stands for "GNU not unix." GNU is usually used with linux as the kernal, for example I use debian on my laptop for work. It's a free OS similar to unix. If you decide to use linux there's more like GUI which is graphical user interface, I use KDE on my laptop and gnome on my desktop.
