Question

Problem C. Fill True or False in the blanks for the following statements. True

1) _ __ Operating system defines the ways in which the system resources are used to solve the computing problems of the users.

2) _ _ Operating system (OS) controls and coordinates use of hardware among various applications and users.
3) ______ System daemons are the first programs to be loaded and executed when powering-up or rebooting a computing system.

4) ______ When an OS runs a user process, it can only run it in the user mode and can never transition to the kernel mode.

5) ______ A system call in a user process is typically executed in the kernel mode.
6) ______ Client-server computing and peer-to-peer computing are two different models for distributed computing.

7) ______ When Apple computers switched from PowerPC to Intel x86, virtualization was used to allow applications compiled for PowerPC to run on Intel x86 by translating every PowerPC instruction.

8) ______ Some virtual machine managers (VMMs) need to run on a host operating system while some VMMs directly run on hardware without the need of a separate host operating system.

9) ______ Virtualization supports running multiple the same or different guest operating systems on a single computing system.

10) _____ A cloud computing environment can only include traditional OSes and VMMs.
11) ______ Real-time OSes have no fixed time constraints.

12) ______ A process control block includes information associated with a process such as process state, the values of program counter and CPU registers when this process was last executed, CPU scheduling information, memory management information, accounting information, and I/O status information.

13) ______ A PCB is typically implemented as a C structure while a ready queue is typically implemented as a linked list.
