What is Architecture | Kernel | Open-source

Architecture:

PC_Architecture

   When referring to computers, architecture or computer architecture is their overall design and layout. Architecture includes where connections and parts of the computer are to be placed, how each of components operate with each other, dimensions, etc. CPU architecture is very similar, except it deals with the arrangement of processor components, how they work together, and the distance between transistors.

Kernel :

          When referring to an operating system, the kernel is the first section of the operating system to load into memory. As the center of the operating system, the kernel need to be small, efficient and loaded into a protected area in the memory; so as not to be overwritten. It can be responsible for such things as disk drive management, interrupt handler, file management, memory management, process management, etc.

Open-Source:

OSI  | OSS

           Open source is a term used to describe a program or file that can be freely modified by anyone. Open source allows users or organizations to adjust the program's functionality to perform for their specific needs. There are numerous open source licensing agreements a program or file may follow. Therefore, it is best to refer to the appropriate documentation to see what the original developer allows and prohibits.
