Return to Kernel (operating system), Linux kernel or Linux topics

Kernel may refer to:

In Computer science:

• Kernel (image processing), a matrix used for image convolution
• Kernel (operating system), the central component of most operating systems
  • Kernel: “The kernel is the program that manages the system, including (depending on the kernel model) hardware devices, memory, and CPU scheduling. It runs in a privileged CPU mode that allows direct access to hardware, called kernel mode.” (SysPrfBGrg 2021)

• Compute kernel, in GPGPU programming
• Kernel method, in machine learning
• In numerical analysis, a subroutine that performs a common numerical operation
  • In particular, a routine that is executed in a vectorized loop; see, e.g., Kernels
• Kernelization, a technique for designing efficient algorithms

• Seed, inside the nut of most plants, especially:
  • Corn kernel
  • Palm kernel
  • Wheat kernel
• Atomic nucleus, the center of an atom

• KERNAL, Commodore's 8-bit OS software
