• What are the types of operating systems mentioned in the study material?

  Single-user single-task, single-user multi-tasking, multi-user, real-time
• What is the role of the operating system in managing networking?

  It manages how computers connect to a network and presents users with available networks
• How does the operating system manage security?

  By restricting user access to certain files or programs and managing user accounts
• What does the operating system manage in terms of memory?

  It manages the Random Access Memory (RAM) and allocates it to running programs
• What is the function of device drivers in an operating system?

  Device drivers manage hardware devices by sending signals to the hardware and translating them for software
• What is the main feature of Android as a mobile operating system?

  It is a free operating system that is customizable by phone manufacturers
• What happens when a user tries to open a second app on the original iPhone?

  The first app would pause, allowing the second one to run
• What is a characteristic of single-user, multi-tasking operating systems?


  They allow the user to open many applications at the same time
• How does multi-tasking work in computers with a single CPU?


  Programs are stored in RAM, and the CPU allocates time to each program to run
• What is a real-time operating system?

  An operating system that must complete executing certain instructions by a specific time
• Give examples of systems that require a real-time operating system.

  Flight-control systems, train management systems
• What is the function of multi-user operating systems?

  They allow many users to access the same computer from their own terminals
• How do operating systems manage network connections?

  They present users with available networks and manage network passwords
• What is the purpose of password protection in operating systems?

  To prevent unauthorized access to user accounts and files
• What happens when a user opens a music player on a phone?


  The music app and song are copied from internal storage to RAM
• What is the effect of using virtual memory on computer speed?

  Using virtual memory slows the computer down due to the time spent moving data
• What are the five roles that operating systems manage?

  • Networking: Manages network connections and protocols
  • Security: Manages passwords and user accounts
  • Memory management: Manages programs and data in RAM
  • Multi-tasking: Allows multiple programs to run simultaneously
  • Device drivers: Manages signals from devices and translates them for software
• How does the role of an operating system extend beyond just the graphical user interface?

  Operating systems manage networking, security, memory, multi-tasking, and device drivers
