Questions and Answers

What is the definition of multiprocessing?

  • The random execution of instructions.
  • The execution of only one instruction at a time.
  • The simultaneous execution of two or more instructions at the same time. (correct)
  • The sequential execution of two or more instructions one after the other.

    • What is the role of a coprocessor in a computer?

  • Monitors the temperature of the CPU to avoid overheating.
  • Speeds processing by executing specific types of instructions while the CPU works on another processing activity. (correct)
  • Acts as the main processor and executes all instructions.
  • Coordinates the execution of all instructions in the CPU.

    • What is a multicore microprocessor?

  • A microprocessor that combines two or more independent processors into a single computer to share the workload. (correct)
  • A microprocessor that executes instructions sequentially.
  • A microprocessor that executes only one instruction at a time.
  • A microprocessor that executes instructions in a random order.

    Study Notes

    Multiprocessing and Parallel Computing

    • Multiprocessing is the use of two or more central processing units (CPUs) within a single computer system to execute multiple instructions simultaneously.

    Coprocessor

    • A coprocessor is a special-purpose processing unit that assists the central processing unit (CPU) in executing specific types of instructions.
    • The coprocessor offloads specific tasks from the CPU, freeing it to perform other processing activities.

    Multicore Microprocessor

    • A multicore microprocessor is a single integrated circuit that contains two or more processing units (cores) that can execute instructions independently.

    Coprocessor vs. Multicore Microprocessor

    • A coprocessor is a separate processing unit that assists the CPU, whereas a multicore microprocessor has multiple processing units within a single chip.
    • Coprocessors are specialized for specific tasks, whereas multicore microprocessors are general-purpose processing units.

    Component Roles

    • Coprocessors are responsible for executing specific types of instructions while the CPU works on another processing activity.

    Parallel Computing

    • Parallel computing is the simultaneous execution of multiple instructions or tasks across multiple processing units or nodes to speed up processing times.

    Massively Parallel Processing Systems

    • Massively parallel processing systems use hundreds or thousands of processing units to execute tasks in parallel, achieving high processing speeds.

    Grid Computing

    • Grid computing is a distributed computing system that coordinates and shares computing resources across a network to achieve a common goal.

    Cloud Computing

    • Cloud computing is a model for delivering computing services over the internet, providing on-demand access to a shared pool of computing resources.

    Storage

    • Secondary storage refers to non-volatile storage devices that hold data when the power is off, such as hard disk drives or solid-state drives.
