Obe informacije i imena datoteka i broj datoteka iz /bin direktorijuma koje počinju sa
Correct Answer
C. Samo broj datoteka iz /bin direktorijuma koje počinju sa bExplanation
The command "ls /bin/b* | wc l" lists all the files in the /bin directory that start with "b" and then pipes the output to the "wc" command with the "l" option. The "wc" command counts the number of lines in the output, which in this case represents the number of files in the /bin directory that start with "b". Therefore, the output will only display the count of files that meet the specified criteria.Rate this question:

Correct Answer
C. Stderr (standardni izlaz za greške)Explanation
The "2>" operator in this context is used to redirect the standard error output. In Unix-like systems, file descriptors are used to represent input, output, and error streams. The number 2 represents the file descriptor for standard error. By using the "2>" operator, any output generated by the command will be redirected to the standard error stream, which is typically displayed as error messages. Therefore, the correct answer is "stderr (standardni izlaz za greške)".Rate this question:

Correct Answer
C. Baferisani ili blokovskiExplanation
The correct answer is "baferisani ili blokovski." This is because the question is asking about the two methods or approaches to accessing files or disks through the cache mechanism. The term "baferisani ili blokovski" refers to buffered or block-based access, which involves reading or writing data in blocks or chunks rather than individually. This method allows for more efficient and faster access to data by utilizing the cache memory to store and retrieve larger amounts of data at once.Rate this question:

The correct answer is "kernelski nivo." In the architecture of the UNIX operating system with 3 levels, the second or middle level represents the kernel level. The kernel is the core component of the operating system that manages the system's resources and provides essential services for the other layers. It interacts directly with the hardware and handles tasks such as memory management, process scheduling, and device drivers. The kernel level is responsible for maintaining the overall stability and functionality of the operating system.Rate this question:

Koji od sistemskih poziva kreira novi proces na UNIX OS: Izaberite jedan odgovor:
- A.
Exec
- B.
Wait
- C.
Exit
- D.
Fork
Correct Answer
D. ForkExplanation
The correct answer is "fork". In UNIX OS, the "fork" system call is used to create a new process by duplicating the existing process. The new process, called the child process, is an exact copy of the parent process, including its memory space and code. After the fork system call, both the parent and child processes continue their execution from the next instruction following the fork. The child process can then execute a different program using the "exec" system call.Rate this question:

- A.
Fork
- B.
Wait
- C.
Exit
- D.
Exec
Correct Answer
B. WaitExplanation
The wait system call allows for process synchronization in UNIX OS. It suspends the execution of the calling process until one of its child processes terminates. This ensures that the parent process waits for the child process to complete before continuing its execution, thereby synchronizing their activities.Rate this question:

In the architecture of a UNIX operating system with 3 levels, the first and lowest level represents the hardware level. This means that at this level, the operating system interacts directly with the hardware components of the computer, such as the processor, memory, and input/output devices. The hardware level is responsible for managing and controlling the physical resources of the computer.Rate this question:
