. Operating System Kernel.

Answer 1

Detailed explanation of the topics mentioned in the question is given below:

1. Open Source Operating Systems: Just like we have an open source code repository (let's say for example on Github) which anyone can access, use and modify, similarly comes the concept of Open Source Operating Systems. It is not only freely available to anyone to view, but also modify, use and share under the terms of open-source licenses such as MIT, Apache etc.

On the contrary, on a closed-source or paid operating system like Windows, the source code can be altered only by Microsoft and can be used by only those (individuals or organisations) who have purchased and paid for the Windows OS.

Examples of Open Source Operating Systems:

Linux, OpenSolaris, Android (mobile phone platform)

2. Operating System Kernel: The Kernel is a computer program at the core of a computer's operating system with complete control over everything in the system. It is that portion of the operating system code that is always resident in memory. It facilitates interaction between the hardware and the software components. In a nutshell, the kernel is the most fundamental part of an Operating System and it can be thought of as a program which controls all other programs on the computer.
