In my understanding, This project is best suited for technical person rather writers only. Expert IT professional is here with more than 06 years work experience. I am from CSE background. I wrote several technical papers. No copy paste work, No third party hiring. I will write from my own knowledge and experience. Thanks -Russel

Give me a chance and i will make your homework immediately after you accept my proposal. The topics of your homework are mostly related with kernel in an OS. Kernel is like a bridge between software and hardware. It connects the software and hardware

I have been developing commercial operating systems almost 15 years. Not only do I deal with this subject matter on an almost daily basis, I can offer a unique and practical viewpoint. Incidentally, I still have my "Dinosaur" textbook (Operating System Concepts, 4th edition by Silberschatz and Galvin). It may not be latest edition, but to be honest, for the questions you posted, very little has changed. Hope to hear from you.

This is all pretty straightforward stuff. Can answer them without reading the text book. However, you mention they should be from the text book, what, like exact sentences? Or just worded very similar? Here's an example answer (without looking at the book) 1.4: Kernel mode instructions are fully priviledged and have full access to all system and CPU resources. User mode instructions are non-priviledged instructions that all programs may run. Dual mode is desirable because a seperation of priviledge allows the operating system kernel to maintain a stable system state, protecting user programs and the operating system itself from either buggy or deliberately malicious user programs. Feel free to contact to discuss further if necessary. Regards, Owen
