  2. Loader (computing) - Wikipedia

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

    In order to load the operating system itself, as part of booting, a specialized boot loader is used. In many operating systems, the loader resides permanently in memory, though some operating systems that support virtual memory may allow the loader to be located in a region of memory that is pageable .

  3. Hazard (computer architecture) - Wikipedia

    en.wikipedia.org/wiki/Hazard_(computer_architecture)

    A structural hazard occurs when two (or more) instructions that are already in pipeline need the same resource. The result is that instruction must be executed in series rather than parallel for a portion of pipeline. Structural hazards are sometimes referred to as resource hazards.

  4. Monolithic kernel - Wikipedia

    en.wikipedia.org/wiki/Monolithic_kernel

    Modular operating systems such as OS-9 and most modern monolithic-kernel operating systems such as OpenVMS, Linux, FreeBSD, NetBSD, DragonFly BSD, Solaris, and AIX can dynamically load (and unload) executable kernel modules at runtime. This modularity of the operating system is at the binary (image) level and not at the architecture level.

  5. Comparison of operating system kernels - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_operating...

    A kernel is a component of a computer operating system. [1] A comparison of system kernels can provide insight into the design and architectural choices made by the developers of particular operating systems.

  6. Load (computing) - Wikipedia

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

    In UNIX computing, the system load is a measure of the amount of computational work that a computer system performs. The load average represents the average system load over a period of time. It conventionally appears in the form of three numbers which represent the system load during the last one-, five-, and fifteen-minute periods.

  7. Automated storage and retrieval system - Wikipedia

    en.wikipedia.org/wiki/Automated_storage_and...

    An AS/RS can be used with standard loads as well as nonstandard loads, [2] meaning that each standard load can fit in a uniformly-sized volume; for example, the film canisters in the image of the Defense Visual Information Center are each stored as part of the contents of the uniformly sized metal boxes, which are shown in the image. Standard ...

  8. Operating system - Wikipedia

    en.wikipedia.org/wiki/Operating_system

    The operating system provides an interface between an application program and the computer hardware, so that an application program can interact with the hardware only by obeying rules and procedures programmed into the operating system. The operating system is also a set of services which simplify development and execution of application programs.

  9. Dynamic linker - Wikipedia

    en.wikipedia.org/wiki/Dynamic_linker

    In computing, a dynamic linker is the part of an operating system that loads and links the shared libraries needed by an executable when it is executed (at "run time"), by copying the content of libraries from persistent storage to RAM, filling jump tables and relocating pointers. The specific operating system and executable format determine ...
