  2. Control register - Wikipedia

    en.wikipedia.org/wiki/Control_register

    A control register is a processor register that changes or controls the general behavior of a CPU or other digital device. Common tasks performed by control registers include interrupt control, switching the addressing mode, paging control, and coprocessor control.

  3. Race condition - Wikipedia

    en.wikipedia.org/wiki/Race_condition

    The memory model defined in the C11 and C++11 standards specify that a C or C++ program containing a data race has undefined behavior. [3] [4] A race condition can be difficult to reproduce and debug because the end result is nondeterministic and depends on the relative timing between interfering threads. Problems of this nature can therefore ...

  4. Segmentation fault - Wikipedia

    en.wikipedia.org/wiki/Segmentation_fault

    Segmentation faults can also occur independently of page faults: illegal access to a valid page is a segmentation fault, but not an invalid page fault, and segmentation faults can occur in the middle of a page (hence no page fault), for example in a buffer overflow that stays within a page but illegally overwrites memory.

  5. C signal handling - Wikipedia

    en.wikipedia.org/wiki/C_signal_handling

    In the C Standard Library, signal processing defines how a program handles various signals while it executes. A signal can report some exceptional behavior within the program (such as division by zero), or a signal can report some asynchronous event outside the program (such as someone striking an interactive attention key on a keyboard).

  6. Memory paging - Wikipedia

    en.wikipedia.org/wiki/Memory_paging

    Also, the page file is rarely read or written in sequential order, so the performance advantage of having a completely sequential page file is minimal. However, a large page file generally allows the use of memory-heavy applications, with no penalties besides using more disk space. While a fragmented page file may not be an issue by itself ...

  7. File locking - Wikipedia

    en.wikipedia.org/wiki/File_locking

    (System calls are available from languages such as C or C++, and shell scripts can make use of noclobber) Using the mkdir command and checking the exit code for failure [11] Lock files are often named with a tilde (~) prefixed to the name of the file they are locking, or a duplicate of the full file name suffixed with .LCK . If they are locking ...

  9. Second Level Address Translation - Wikipedia

    en.wikipedia.org/wiki/Second_Level_Address...

    A hardware page table walker can treat the additional translation layer almost like adding levels to the page table. Using SLAT and multilevel page tables, the number of levels needed to be walked to find the translation doubles when the guest-physical address is the same size as the guest-virtual address and the same size pages are used.
