Red Hat RedHat Linux 9.0

RedHat Linux is the most popular cold operating system in the world. Because it has the best graphic interface, it is very convenient to install, configure, and use, and runs stably, so it is highly appreciated by new users and old players. Now, RedHat Linux has a new version of 9.0, and has made great progress on the basis of the original version. It improves the graphic interface, enhances hardware compatibility, and is more handy for installation, especially enhances multimedia capabilities-the new version of xfree 4.0.1 allows you to play multimedia files in Linux. It also uses the OpenSSL 128-bit encryption technology to make your network communication more secure. The latest kernel provides support for USB interface mouse and keyboard; provides graphical desktop and Graphical Kernel adjustment and firewall configuration tools that are easier to configure and manage. In short, RedHat Linux 9.0 is your best choice whether you are a novice or an old Linux player, whether you are an individual or an enterprise server.
