    • Exec

    • Wait

    • Exit

    • Fork

    Correct Answer
    A. Exit
    Explanation
    The correct answer is "exit." The exit system call allows a process to terminate and return an exit status to the parent process. When a process calls the exit system call, it releases all its resources and terminates. The exit status can be used by the parent process to determine the outcome of the terminated process.

    Baferski keš, kešira sledeće: Izaberite jedan odgovor:

    • Blokove na disku, tj delove datoteka

    • Procese

    • Stranice virtulene memorije

    • Pakete za mrežne komunikacije

    Correct Answer
    A. Blokove na disku, tj delove datoteka
    Explanation
    The correct answer is "blokove na disku, tj delove datoteka." This is because the term "Baferski keš" refers to a cache memory that stores blocks of data from disk files. These blocks are accessed more frequently, so they are stored in the cache to improve the system's performance by reducing the time it takes to access the disk. Therefore, the correct answer refers to blocks on the disk, which are parts of files.

    Koliko blokova čita algoritam breada: Izaberite jedan odgovor:

    • 1

    • 0

    • Zavisi od zahteva

    • 2

    • 1 ili 2

    Correct Answer
    A. 1 ili 2
    Explanation
    The algorithm of Breadth-First Search (BFS) reads one or two blocks. This is because BFS explores all the vertices at the current level before moving to the next level. Therefore, it reads one block for the current level and potentially reads an additional block for the next level if there are any adjacent vertices.

    Imate datoteke /tmp/a.a i /tmp/b.b koje niko nije otvarao. Proces obavi sledeću sekvencu sistemskih poziva fd1=open(/tmp/a.a, O_RDONLY,0) fd2=open(/tmp/a.a, O_RDWR,0) fd3=open(/tmp/b.b, O_WRONLY,0) count1=read(fd1, buffer,200) count2=read(fd2, buffer,100) count3=read(fd3, buffer,300) Odrediti pomeraj offset za sledeće čitanje iz datoteke /tmp/b.b za desktriptor fd3 Izaberite jedan odgovor:

    • 100

    • 0

    • 101

    • 301

    • 201

    • 200

    • 300

    Correct Answer
    A. 300
    Explanation
    The offset for the next read from the file /tmp/b.b for file descriptor fd3 is 300. This is because the process has already performed the system call "open(/tmp/b.b, O_WRONLY,0)" to open the file with write-only access. Since no other operations have been performed on this file descriptor, the current offset is 0. The next read operation will start reading from the offset of 0 and read 300 bytes from the file. Therefore, the offset for the next read will be 300.

    Da bi ste promenili / (root direktorijum) na UNIX OS, upotrebićete sledeći sistemski poziv: Izaberite jedan odgovor:

    • Chmod

    • Chown

    • Chdir

    • Chroot

    Correct Answer
    A. Chroot
    Explanation
    The correct answer is chroot. To change the root directory on a UNIX OS, the chroot command is used. This command allows the user to run a process or a command with a different root directory, effectively isolating it from the rest of the system. This can be useful for security purposes or when testing software in a controlled environment.
