• What is the purpose of a user interface in an operating system?

  It provides a method for users to interact with a computer.
• What does memory management in an operating system involve?


  It involves managing programs and data stored in RAM and freeing up memory when a program is closed.
• What is multitasking in the context of an operating system?

  It is the ability to run two or more programs at once.
• What is the role of peripheral management in an operating system?

  It manages devices such as mice and printers.
• What does user management in an operating system entail?

  It involves managing usernames, passwords, and access permissions for users.
• What is file management in an operating system?


  It is the organization of files on storage drives, including naming, moving, saving, copying, and deleting files.

• What is system software?


  It is the software that provides a platform for other software to work, including operating systems and utility programs.
• What are the main responsibilities of operating systems?

  They manage computer hardware, users, and the resources used by software.
• What features do graphical user interfaces (GUIs) have?


  They include pointers, windows, menus, icons, and drag-and-drop functionality.
• How do smartphone interfaces differ from desktop interfaces?

  Smartphone interfaces generally take up the full screen and do not use pointers.
• What does the acronym WIMP stand for in traditional GUIs?


  Windows, Icons, Menus, and Pointers.
• What is a command line interface (CLI)?

  It is an interface where text commands are entered into the computer.
• What are the advantages of using a command line interface?

  It requires very little processing power and can be faster for expert users.
• What are menu-driven interfaces commonly used for?

  They are often used by devices with dedicated functions, such as MP3 players and ATM machines.
• Why must the operating system manage memory?


  To ensure that programs and their data are properly loaded and do not overwrite each other.
• What is the purpose of interrupts in an operating system?

  They are signals sent to the CPU to indicate an event that needs immediate attention.
• What are hardware interrupts?

  They are generated by hardware devices to signal events, such as a printer running out of paper.
• What are software interrupts?

  They are generated by programs to indicate errors, such as a divide-by-zero error.
• What is the role of device drivers in an operating system?

  They are programs that control peripheral devices and communicate with the OS.
• How does the operating system handle data sent to a printer?

  The data is sent to a print queue or buffer, where it is transmitted to the printer page by page.
• What is the function of the print queue?


  It shows the status of each job in the queue, indicating whether it is printing or waiting.
• What does the operating system do for disk and file management?

  It manages where files are written on the disk, keeps track of their locations, and prevents overwriting.
• What features are included in file management by the operating system?


  Features include naming files, allocating files to folders, moving, saving, copying, and deleting files.
• What is the purpose of access rights in user management?

  Access rights ensure that users can only see their own files and have different levels of permissions.
• What is the role of the operating system in user logins?

  It is responsible for storing all users and their passwords in a file or database.
