    T vreme prenosa ka/od diska =

    • Broj bajtova za prenos / (broj bajtova na stazi * brzina rotacije)

    • Broj bajtova za prenos * (broj bajtova na stazi / brzina rotacije)

    • (Broj bajtova za prenos / broj bajtova na stazi) * brzina rotacije

    • Option 4

    Correct Answer
    A. Broj bajtova za prenos / (broj bajtova na stazi * brzina rotacije)
    Explanation
    The correct formula for calculating the transfer time from/to the disk is given by dividing the number of bytes to be transferred by the product of the number of bytes per track and the rotation speed. This formula takes into account the number of bytes to be transferred, the density of data on the track, and the speed at which the disk is rotating. By dividing the number of bytes to be transferred by the product of the number of bytes per track and the rotation speed, we get the time it takes to transfer the data.

    • Zavisno od konf. moze a ne mora da prolazi kroz DMA

    • Nikada ne prolazi kroz DMA vec ga odrediste uzima sa magistrale

    • Option 4

    Correct Answer
    A. Zavisno od konf. moze a ne mora da prolazi kroz DMA
    Explanation
    Depending on the configuration, the data may or may not pass through the DMA. The DMA (Direct Memory Access) is a feature that allows data to be transferred between devices without involving the CPU. In some configurations, the data may be directly accessed from the bus by the destination device, bypassing the DMA. However, in other configurations, the data may need to pass through the DMA for the transfer.

    Kod adresiranja steka koristimo:

    • Indirektno adresiranje

    • Implicitno adresiranje

    • Neposredno adresiranje

    • Option 4

    Correct Answer
    A. Implicitno adresiranje
    Explanation
    Implicitno adresiranje se koristi kada se operand za instrukciju automatski određuje na osnovu konteksta ili prethodno definisanih pravila. Ovo znači da se adresa operand-a ne mora eksplicitno navesti u instrukciji. Umesto toga, adresa se dobija implicitno iz registra ili nekog drugog dela memorije. U ovom slučaju, implicitno adresiranje se koristi za adresiranje steka.

    Rate this question:

    • Promenljive u memoriji i/ili registrima CPU

    • Promenljive u memoriji

    • Option 4

    Correct Answer
    A. Promenljive u memoriji
    Explanation
    Indirektno adresiranje adresira promenljive u memoriji. This means that indirect addressing is used to access variables stored in memory. It allows the program to access the value of a variable indirectly, by using a memory address instead of directly referencing the variable itself. This can be useful in situations where the exact memory location of a variable may not be known or may change dynamically during program execution. By using indirect addressing, the program can access and manipulate variables in memory more flexibly.

    Implicitno adresiranje adresira:

    • Promenljive u memoriji

    • Konstante u memoriji

    • Promenljive u registrima CPU

    • Option 4

    Correct Answer
    A. Promenljive u registrima CPU
    Explanation
    Implicitno adresiranje adresira promenljive u registrima CPU. Implicitno adresiranje je način adresiranja u kojem se adresa operanda ne navodi eksplicitno, već se podrazumeva da se operand nalazi u registru CPU. Ovo znači da se vrednost promenljive direktno koristi iz registra, bez potrebe za eksplicitnim navođenjem adrese u memoriji. U ovom slučaju, implicitno adresiranje se koristi za adresiranje promenljivih koje su smeštene u registrima CPU.

    • Option 4

    Correct Answer
    A. Menjaju sadrzaj programskog brojaca
    Explanation
    The correct answer is "Menjaju sadržaj programskog brojača." This answer is correct because operations for controlling the flow of a program often involve changing the value of the program counter. The program counter is a register that keeps track of the memory address of the next instruction to be executed. By modifying the program counter, the control flow of the program can be altered, allowing for branching, looping, and other control structures.

    • Option 4

    Correct Answer
    A. Izmedju kesa i RAM se prenose blokovi
    Explanation
    The correct answer is "Izmedju kesa i RAM se prenose blokovi." This answer states that blocks are transferred between cache and RAM. This is a common practice in computer architecture, where the cache is used to store frequently accessed blocks of data from RAM, allowing for faster access times. By transferring blocks instead of individual words or frames, the cache can effectively store and retrieve larger chunks of data, improving overall performance.

    • Obe pomenute vrste RAM memorija

    • DRAM

    • SRAM

    • Option 4

    Correct Answer
    A. DRAM
    Explanation
    DRAM stands for Dynamic Random Access Memory, which is a type of volatile memory used in computers for the main memory. It is cheaper compared to SRAM (Static Random Access Memory) and is slower in terms of access speed. DRAM stores each bit of data in a separate capacitor within an integrated circuit, which needs to be constantly refreshed to maintain the data. This makes DRAM essentially analog in nature. Therefore, the given statement suggests that DRAM is analog in nature.
