The kernel
The kernel is the core part of an operating system. It manages low level hardware access, memory, processes, and communication between software and hardware.

Drivers are software components that help the operating system communicate with specific hardware. A graphics driver, for example, helps the OS and apps use the GPU properly.
Operating system updates are not only cosmetic. They often fix security weaknesses, compatibility problems, performance issues, and reliability bugs.
