As there are many terms to such a large project like Elastos and Cyber Republic, we’ve decided to build a growing glossary of terms that can help the less technically acquainted understand better what the tech means and the impact it could have. This week we’re focusing on Kernel.

Term: Kernel

“The kernel is the central module of an operating system (OS). It is the part of the operating system that loads first, and it remains in main memory. Because it stays in memory, it is important for the kernel to be as small as possible while still providing all the essential services required by other parts of the operating system and applications. The kernel code is usually loaded into a protected area of memory to prevent it from being overwritten by programs or other parts of the operating system.

“Typically, the kernel is responsible for memory management, process and task management, and disk management. The kernel connects the system hardware to the application software. Every operating system has a kernel. For example the Linux kernel is used numerous operating systems including Linux, FreeBSD, Android and others.”


Layman’s Terms: 

Kernel is the program that controls all other programs.  It is the heart of each Operating System, its Source Code. It does all the stuff the user never sees like managing the hardware, checking the memory and assigning memory space, and forwarding requests.  It helps with multitasking. 

Kernel processes are similar to daemon processes, except that kernel processes are more powerful and less flexible.
