Test 1: Operating Systems Why Does Threads have private Registers? Threads have stacks? Why? During a Interrupt, which stack is utilized? User level or kernel level? C) . Difference between Kernel thread, kernel-level thread and a process being executed in kernel mode? 3 advantages and 3 disadvantages of memory shared and client- server for IPC? Once the information is copied from user memory to kernel memory, why does it make sense allow a kernel thread to finish handling the information? If code in the kernel needs to access user space, do you need to wait for a context-switch? before you can gain access? Explain . Test 1: Operating Systems Why Does Threads have private Registers?
