Read the first 7 Operating Systems & Platforms flashcards as text

  1. Which CPU scheduling algorithm gives each process a fixed time slice in turn?

    Answer: Round robin

    Round robin rotates through ready processes and gives each one a fixed time quantum.

  2. How do containers like Docker mainly differ from virtual machines?

    Answer: Containers share the host OS kernel

    Containers isolate processes but share the host kernel, so they're lighter than VMs.

  3. Which Windows edition includes BitLocker and can join an Active Directory domain?

    Answer: Windows 11 Pro

    Pro adds domain join, Group Policy, and full BitLocker, which Home doesn't have.

  4. What is a key advantage of a symbolic link over a hard link on Linux?

    Answer: It can point across different file systems

    Symlinks store a path, so they can cross file systems, while hard links must stay on the same file system.

  5. Which journaling file system is the default on many Linux distributions such as Debian and Ubuntu?

    Answer: ext4

    ext4 is a journaling file system and the common default on Debian-based Linux.

  6. What does preemptive multitasking let the operating system do?

    Answer: Interrupt a running process to give the CPU to another

    With preemptive multitasking, the OS scheduler can take back the CPU, so one app can't take it over.

  7. A company wants to push security policies to, and remotely wipe, employees' iOS and Android phones. What should it use?

    Answer: Mobile device management (MDM)

    MDM platforms enroll mobile devices so the company can enforce policies, push apps, and wipe them remotely.
