    Correct Answer
    A. Za modelovanje sistema u cilju merenja deadlocka
    Explanation
    The correct answer suggests that the structure in the picture is mainly used for modeling systems in order to measure deadlocks. This means that the structure depicted in the picture is designed to represent and analyze situations where multiple processes are unable to proceed because each is waiting for the other to release a resource. By using this structure, one can simulate and evaluate the occurrence and impact of deadlocks in a system.

    • Deadlock detection algorithm

    • Banker algorithm

    • Deadlock prevention algorithm

    • Ostrich algorithm

    Correct Answer
    A. Banker algorithm
    Explanation
    The correct answer is Banker algorithm. The Banker algorithm is used to prevent deadlock in a system by dynamically allocating resources to processes. It works by keeping track of the available resources, the maximum resources each process can request, and the resources currently allocated to each process. Before granting a request, the algorithm checks if it will leave the system in a safe state, meaning that there will always be a way to satisfy the remaining processes' resource requests. If the request would lead to an unsafe state, it is denied. This algorithm helps in avoiding deadlock situations by carefully managing resource allocation.

    Correct Answer
    A. Hardvera
    Explanation
    In the given question, the correct answer is "Hardvera". This means that in the structure of a computer system, the operating system (OS) is directly above the hardware. The hardware refers to the physical components of the computer system such as the processor, memory, storage devices, and input/output devices. The operating system interacts with the hardware to manage and control its resources, allowing the software (system software, application software, and network layer) to run efficiently on the computer system.

    Identifikujte short term scheduler algoritam, pa ga ocenite po pitanju preemption - ProProfs

    Identifikujte short term scheduler algoritam, pa ga ocenite po pitanju preemption

    • Zavisi od Os

    • Preemptive

    • Ne moze se odrediti

    • Non preemptive

    • Uslovno preemptive

    Correct Answer
    A. Preemptive
    Explanation
    The given answer is "Preemptive." This means that the short term scheduler algorithm can interrupt or preempt a running process in order to allocate the CPU to another process. This allows for better responsiveness and priority management in the system. However, without further information, it is not possible to determine the specific algorithm being referred to.

    U slučaju ulaska nekih procesa u deadlock, za sistem sa Deadlock detection algoritmom, najbolja metoda je:

    • Rollback

    • Ovakav sistem nikada nece uci u deadlock

    • Detekcija kruga i razbijanje kruga unistavajuci sve procese u krugu

    • Detekcija kruga i razbijanje unistavajuci jedan ili vise procesa

    Correct Answer
    A. Rollback
    Explanation
    The best method in case of processes entering a deadlock in a system with a Deadlock detection algorithm is to perform a rollback. Rollback involves reverting the state of the system to a previous checkpoint before the deadlock occurred, allowing the system to recover and continue running without the deadlock. This approach ensures that the system can resolve the deadlock and resume normal operation without the need to terminate or destroy any processes.

    Objasniti MVT. Koji algoritam za MVT ne mora da analizira postojeće šupljine, prilikom alokacije memorije.

    • First-fit

    • Best fit

    • Worst fit

    Correct Answer
    A. First-fit
    Explanation
    The explanation for the correct answer, which is "first-fit," is that the first-fit algorithm does not need to analyze existing holes or gaps in memory during the memory allocation process. It simply allocates the first available block of memory that is large enough to accommodate the requested size. This algorithm is efficient and fast, but it may lead to fragmentation over time as smaller gaps are left between allocated blocks.

    Potpunu CPU izolaciju u odnosu na i/o akcije omogucavaju dva hardverska uredjaja. To su:

    • MMU I DMA

    • MMU i timer

    • MDA i timer

    • MDA I PIC

    • PIC i mrezna kartica

    • MMU I PIC

    Correct Answer
    A. MDA I PIC
    Explanation
    The correct answer is MDA I PIC. MDA stands for Memory Direct Access, which allows the CPU to directly access memory without going through the CPU. PIC stands for Programmable Interrupt Controller, which manages and prioritizes interrupt requests from various devices. Both MDA and PIC contribute to the complete isolation of the CPU from I/O actions. MDA allows direct memory access, reducing the CPU's involvement in I/O operations, while PIC manages interrupts, ensuring that the CPU is not interrupted unnecessarily during I/O actions.
