Which of the following is a basic function all computers perform? (Choose three.) processing Internet access graphics input email output 2. Which of the following executes instructions provided by computer programs? NIC USB CPU drive 3. You are asked to develop a process that runs in the background and handles network communications. What type of process should you develop? service ISR kernel foreground 4. Which of the following is a feature typically provided by an operating system? (Choose two.) file system spreadsheet database app kernel 5. A friend of yours described a program he is writing that runs on a microcontroller and will read sensors and write to devices that control industrial equipment. What type of system is his program most likely working with? general-purpose operating system multiuser operating system embedded system multitasking system 6. While on a coffee break, your colleague asserts that cooperative multitasking is the best operating system design. What is your response? (Choose three.) A disadvantage of cooperative multitasking is that it relies on each program to decide when to give control back to the operating system. Cooperative multitasking can be faster than other forms of multitasking because it increases the clock speed of the processor. Cooperative multitasking OSs can freeze due to a process getting stuck in an infinite loop. Modern operating systems use preemptive multitasking so that the operating system is fully in control. Cooperative multitasking is best used on real-time operating systems. 7. You have been asked to recommend an operating system for a project that requires precise timing of I/O devices and deterministic response times to events. Which OS should you recommend? Android VxWorks Linux PDP-10 8. Which of the following is best to run on a client operating system? DHCP server Active Directory virtualization Web browser 9. Which component of the operating system gets called when a process must be allocated memory and scheduled to run? kernel user interface file system application 10. A new application you are installing is critical to business operations and downtime is to be avoided. In addition, fast response times are necessary, so performance must be scaled when more users start using the system. What OS and server hardware feature should you consider implementing on the system on which the application is installed? single-tasking interrupts real-time clustering 11. Which of the following best describes the MS-DOS operating system? client real-time standalone embedded 12. Which of the following are you most likely to find in firmware? kernel bootstrap LILO ISR 13. A colleague asks you where the code for the power-on self-test is located. What do you tell her? bootloader hard disk non-volatile memory random access memory 14. You're writing a program that must enable and disable interrupts. In which CPU mode must your program operate? user mode real-time mode POST mode kernel mode 15. Your manager has asked you to terminate a process running on a Linux server. Before you can terminate the process, what information do you need? the PID the file handle the IRQ number the I/O address 16. Which of the following are ways that a process is created? (Choose two.) by the bootloader by the BIOS POST routine by a file handle by the user 17. Which of the following is performed by the BIOS? (Choose two.) runs the power-on self-test starts the operating system manages the file system allocates memory to applications 18. Which method of I/O handling uses a round-robin technique? interrupts NMI polling RTOS 19. Which type of operating system is most likely to be part of an embedded system? task-switching cooperative multitasking real-time batch processing 20. Which aspect of security and protection services verifies that an account has permission to perform an action on an o
