"Kerogen" Natural Recordings by Native Speakers
Kerogen is a waxy, organic substance derived from the remains of tiny plants and animals that lived millions of years ago. It is found in sedimentary rocks, such as shale and coal, and is a rich source of fossil fuels, including oil and natural gas.
The kernel is the central part of an operating system that manages the system's hardware resources. It acts as a bridge between the application programs and the hardware resources, controlling the allocation of resources such as memory and CPU time.
