6.3 Operating systems

• What is the primary role of an operating system (OS)?

  Manages hardware and resources
• The file system management function organizes files and directories for storage and retrieval.
• A graphical user interface (GUI) is an example of a user interface provided by an operating system.
• What does the security control function of an OS manage?

  Access control and permissions
• Match the OS component with its function:

  Kernel ↔️ Core of the OS

  Device Drivers ↔️ Hardware interface

  System Utilities ↔️ OS tools

  User Interface ↔️ User interaction
• The hardware management function controls access to CPU, memory, and peripherals.
• The user interface function allows users to interact with the computer.
• What does the security and access control function protect the system from?

  Unauthorized access
• Match the OS function with its description:

  Hardware Management ↔️ Controls CPU and memory

  Resource Allocation ↔️ Coordinates usage for applications

  User Interface ↔️ Enables user interaction

  Security Control ↔️ Protects system access
• The hardware management function controls access to CPU, memory, and peripherals.
• What type of interface allows users to interact with the computer?

  User Interface
• The file management function organizes files and directories for storage.
• Match the type of OS with its example:

  Batch OS ↔️ IBM OS/360

  Time-Sharing OS ↔️ Unix

  Real-Time OS ↔️ VxWorks

  Distributed OS ↔️ Amoeba
• What is an Operating System (OS)?

  Manages hardware and software
• A single-user operating system supports one
• Match the type of OS with its example:

  Single-user ↔️ MS-DOS

  Multi-user ↔️ Unix

  Multitasking ↔️ Windows

  Real-time ↔️ VxWorks
• MS-DOS is an example of a multi-user operating system.

  False
• A multitasking OS allows multiple applications to run concurrently
• Which operating system is used in embedded systems and guarantees a fast response to events?

  VxWorks
• A multitasking OS allows users to switch between applications seamlessly.
• The type of OS used depends on specific system requirements like multi-user support or real-time processing
• What is the primary role of process management in an operating system?

  Managing programs in execution
• Arrange the key aspects of process management in the correct sequence:

  1️⃣ Creating and terminating processes

  2️⃣ Scheduling processes for CPU execution

  3️⃣ Synchronizing processes to avoid conflicts

  4️⃣ Communicating between processes
• Match the process management component with its function:

  Process Scheduler ↔️ Allocates CPU time

  Process Synchronizer ↔️ Avoids data conflicts
• Process synchronization is necessary to avoid data conflicts between processes.
• One key aspect of process management is creating and terminating processes
• Process Management is a critical function of an Operating System (OS) that involves managing processes
• Process management includes scheduling processes for CPU execution.
• What is one purpose of synchronizing processes in process management?

  Avoid conflicts
• The Process Scheduler decides which process to execute next
• What does the Process Control Block (PCB) store information about?

  Each process
• Inter-Process Communication (IPC) enables data exchange between processes.
• In a multitasking OS like Windows, process management allows multiple applications to run concurrently
• What other OS functions is process management closely related to?

  Memory management and file management
• An operating system (OS) coordinates CPU usage, memory allocation, device interaction, file system management, and security
• Resource allocation is a key function of an operating system.
• What is the purpose of the user interface in an operating system?

  Interact with the computer
• Match the operating system component with its function:

  Kernel ↔️ Manages CPU and memory

  Device Drivers ↔️ Translates between OS and hardware

  System Utilities ↔️ Performs file management
• What is one example of hardware management performed by an operating system?

  Controls CPU access
• Resource allocation by an OS coordinates usage for multiple applications.
