Red Hat Enterprise Linux 6.4 (RHEL 6.4) was released in February 2013, continuing the tradition of excellence and innovation that Red Hat has become known for in the world of open-source operating systems. One of the key features of RHEL 6.4 is the Yellowdog Updater, Modified (YUM) package manager, which simplifies the process of installing, updating, and managing software packages on the system.

YUM is a powerful tool that allows system administrators to easily install and maintain software packages on RHEL systems. With YUM, administrators can easily search for available packages, install or update them with a single command, and resolve dependencies automatically. This makes it much easier to keep the system up-to-date and secure, as administrators can quickly install security updates and patches as soon as they are released.

In RHEL 6.4, YUM has been updated to provide faster performance and improved reliability. The update process has been optimized to reduce the time it takes to download and install packages, making it more efficient for administrators to keep their systems updated. In addition, YUM now supports more repositories and mirrors, making it easier to find and install software packages from a variety of sources.

Another key feature of RHEL 6.4 is the ability to create custom YUM repositories, allowing organizations to create their own repositories of software packages for distribution within their network. This can help to streamline the process of installing and updating software on multiple systems, as administrators can create a centralized repository of approved packages that can be easily accessed by all systems on the network.

Overall, RHEL 6.4 with YUM is a powerful and flexible operating system that makes it easy for system administrators to manage software packages on their systems. With its fast performance, automatic dependency resolution, and support for custom repositories, YUM provides a robust package management solution that is ideal for organizations of all sizes.

In conclusion, Red Hat Enterprise Linux 6.4 with YUM is a great choice for organizations looking for a reliable and secure operating system that is easy to manage and maintain. With its powerful package management capabilities, RHEL 6.4 makes it easy for system administrators to keep their systems up-to-date and secure, ensuring that they have access to the latest software packages and security updates. Whether you are a small business or a large enterprise, RHEL 6.4 with YUM is an excellent choice for your organization's operating system needs.
