UNIX Process - Learning of a Classic never ends

Learning never stops and if it is a classical subject every becomes teacher in no time and student in no time. With a bit of optimism, let me put my thoughts here. Surely comments are welcome and all comments will be put in the hall of fame of this online magazine.

Today, I got sometime to think :-) and thought that I should start writing on processes. For anyone who is new/old the right place to get a start is process. Before getting started, the objectives of this entire article to discuss on process with sufficient details. Moving forward, this blog will have tutorials/scribblings on Unix Externals/Internals.

1. What is process? How it looks like?
2. As an user how one can see the process in your Unix/Linux System?
3. What are various states of process? How they transition?
4. What are the important terminology and data structure needed to continue my journey?
5. Why I need kernel to run my process? I have written "Hello, World" program, why I need kernel to run and get the output?
6. What are various modes/context?
7. How processes switch between modes and contexts? What is the object of those switches?
8. What are the commonly used commands/utilities that are related to the process/process management?
9. Is it going to be a theory? Can you give me code and explain stuffs? Can you also give me license to use the example as per my wish?
