  2. Bus error - Wikipedia

    en.wikipedia.org/wiki/Bus_error

    In modern use on most architectures these are much rarer than segmentation faults, which occur primarily due to memory access violations: problems in the logical address or permissions. On POSIX-compliant platforms, bus errors usually

  4. Shell (computing) - Wikipedia

    en.wikipedia.org/wiki/Shell_(computing)

    In the lower right we can see a terminal emulator running a Unix shell, in which the user can type commands as if they were sitting at a terminal. In computing , a shell is a computer program that exposes an operating system 's services to a human user or other programs.

  5. 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.

  6. Bus (computing) - Wikipedia

    en.wikipedia.org/wiki/Bus_(computing)

    An address bus is a bus that is used to specify a physical address. When a processor or DMA-enabled device needs to read or write to a memory location, it specifies that memory location on the address bus (the value to be read or written is sent on the data bus). The width of the address bus determines the amount of memory a system can address.

  7. List of IRC commands - Wikipedia

    en.wikipedia.org/wiki/List_of_IRC_commands

    This command is often used to obtain the IP of an abusive user to more effectively perform a ban. It is unclear what, if any, privileges are required to execute this command on a server. This command is not formally defined by an RFC, but is in use by some IRC daemons. Support is indicated in a RPL_ISUPPORT reply (numeric 005) with the USERIP ...

  8. Page fault - Wikipedia

    en.wikipedia.org/wiki/Page_fault

    Illegal accesses and invalid page faults can result in a segmentation fault or bus error, resulting in an app or OS crash. Software bugs are often the causes of these problems, but hardware memory errors, such as those caused by overclocking, may corrupt pointers and cause valid code to fail.

  9. User space and kernel space - Wikipedia

    en.wikipedia.org/wiki/User_space_and_kernel_space

    The term user space (or userland) refers to all code that runs outside the operating system's kernel. [2] User space usually refers to the various programs and libraries that the operating system uses to interact with the kernel: software that performs input/output, manipulates file system objects, application software, etc.
