Dear yancom-ga;
Thank you for allowing me an opportunity to answer your interesting
question.
The four major divisions of an operating system are Kernel, File
System, I/O System and Shell.
KERNEL: A kernel arranges the memory management for all the running
processes, and makes sure they all get a fair (or unfair, if you
please) share of the CPU's attention. It also provides a nice, fairly
portable interface for programs to talk to your hardware.

FILE SYSTEM: a hierarchical system of folders-within-folders
containing individual files that in turn consist of one or more
strings of bytes

I/O SYSTEM: Basically, an I/O system is a series of calls and
functions through which your computer searches for programs via
designated substrings (calls) and orders the program matching that
substring to begin its designated action (function).

SHELL: A shell is basically a user interface that acts as a command
interpreter. It converts the commands of the user into input that the
computer understands, thus resulting in an action or function.

I hope you find that that my research exceeds your expectations. If
you have any questions about my research please post a clarification
request prior to rating the answer. I welcome your rating and your
final comments and I look forward to working with you again in the
near future. Thank you for bringing your question to us.
Best regards;
Tutuzdad-ga
