Can you explain the concept of the kernel space in an operating system?

The kernel space is a region of memory in the operating system where the kernel and its components run with high privileges. Device drivers, process schedulers, memory management, and other system services operate in this space.

The difference from user space is that code in the kernel space has full access to hardware and memory, whereas user programs operate with limited rights for system security and stability.

For example, when an application requests to read a file, the request transitions from user space to kernel space, where interaction with the file system and devices occurs.
