In the context of a Fedora-RHEL `dnf update` and `dnf upgrade`, `kernel-modules` for `x86_64` architecture refers to a package that contains loadable modules for the Linux kernel. These modules extend the functionality of the kernel without the need to reboot the system. They can provide support for various hardware components, file systems, network protocols, and more.

1. Key Points:
2. **Kernel Modules**: These are pieces of code that can be loaded into the kernel as needed. They allow the kernel to be extended without the need to reboot the system.
3. **x86_64**: This denotes the 64-bit architecture for x86 processors, which is commonly used in modern computers.

1. Purpose:
2. **Hardware Support**: Kernel modules can provide drivers for various hardware components, such as graphics cards, network adapters, and storage controllers.
3. **File Systems**: Modules can add support for additional file systems not included in the base kernel.
4. **Network Protocols**: They can also enable support for additional network protocols and features.

1. Usage in `dnf update` and `dnf upgrade`:
2. When running `dnf update` or `dnf upgrade`, the `kernel-modules` package ensures that the system has the latest and most compatible kernel modules installed.
3. Keeping these modules updated is crucial for system stability, security, and performance, especially after a kernel update.

In summary, the `kernel-modules – x86_64` package in Fedora is essential for maintaining and extending the functionality of the Linux kernel on a 64-bit system.
