Consider an operating system that have three process states, READY, BLOCKED, and RUN- NING. The READY state means that the process is waiting to be assigned to a processor. The RUUNING state means that instructions of the process are being executed on the CPU. The BLOCKED state means that the process is waiting for an I/O completion event. Answer the following questions:
(a) Draw a process state transition diagram.
(b) Explain what may cause a process to enter each state, and when a scheduling decision must be made to switch to a different process.
(c) Explain the concept of context switch and the source of context switch cost.
(d) Can the operating system support preemptive scheduling?
2. Let us consider the following C program running in a POSIX system. int main() { fork() fork) fork() return 0;
(a) How processes will be created?
(b) Justify your answer.

okay, so i know we just goofed around in that chat, but ive been like genuinly depressed, like medically depressed for almost 4 years now. i had my first panic attack when i was 8. i woke my mum up and told her i felt like i was in a dream. like i was a goldfish in a bowl, looking at all these things going on around me and feeling . tiny. wort hless. and i now am now 17 y/o. i still feel those emotions daily. life used to go by so quick.like every day i would wake up and just like want to go back to bed cause i always felt like i was in the wrong place. i guess looking back, i was in the wrong state of mind. i took a expensive like nice trip to whyoming with my grandfather and ha ted it. like idk why. i would have loved it now, but i found myself writing in a journal everyday because i would forget what happened the day before, couldnt remember what i ate for like the previous meal. just my memory left me for the week i was there. worst feeling ive ever experienced.
