Computer Science I'm working on project about building an operating system simulator and in the description of the project under the section about I/O management, the requirement is two typed of I/O event must be handled. One come from a process and the other one come from external (e.g hardware peripherals) which may happen at moment and caused by process being executed by CPU. So I dont really know what to do here? is it asking to implement some kind of disk scheduling algorithms? im doing the project in python btw
Dynamic memory is defined as follows: what is it and how does it vary from conventional memory?
A "dynamic memory" is a kind of "memory" that may be accessed at any time.
What, exactly, is a "memory void?" When it happens, how does the operating system handle it, and what causes it?
What is the difference between processes that are I/O-bound, CPU-bound, and memory-bound?
In operating system, each process has its own a) address space and global variables b) open files c) CPU state d) all of the mentioned

Memory management is the functionality of an operating system which handles or manages primary memory and moves processes back and forth between main memory and disk during execution. Memory management keeps track of each and every memory location, regardless of either it is allocated to some process or it is free. Given five memory partitions of 110 KB, 450 KB, 100 KB, 250 KB, and 500 KB (in order), how would each of the first-fit, best-fit, and worst-fit algorithms place processes of 212 KB, 417 KB, 112 KB, and 426 KB (in order)?Which algorithm makes the most efficient use of memory? Write a program to compare and justify your answer.
