Final answer:
In general, other threads in the same process can read from a file opened with read privileges by one thread, and threads in another process can also read from that file if they have the necessary permissions. It is not typically true that other threads cannot read from the file.
Step-by-step explanation:
When one thread opens a file with read privileges in a computing context, the following are typical behaviors:
- Other threads in the same process usually can also read from that file because they share the same file descriptors or handles.
- Other threads in another process can also read from the file if they have the necessary permissions, since file access control is typically managed at the operating system level, not by individual processes or threads.
- It is not correct that any other thread cannot read from that file; it depends on the operating system's permissions and whether the file has been exclusively locked.
- All of the mentioned conditions can be true under specific circumstances, depending on the file system and operating system.
Therefore, the option b) Other threads in the same process can also read from that file is generally true, alongside option a) Other threads in another process can also read from that file, assuming proper permissions are in place.
