  2. Booting process of Linux - Wikipedia

    en.wikipedia.org/wiki/Booting_process_of_Linux

    The system startup stage on embedded Linux system starts by executing the firmware / program on the on-chip boot ROM, which then load bootloader / operating system from the storage device like eMMC, eUFS, NAND flash, etc. [5] The sequences of system startup are varies by processors [5] but all include hardware initialization and system hardware ...

  3. 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 .

  4. Structural load - Wikipedia

    en.wikipedia.org/wiki/Structural_load

    A structural load or structural action is a mechanical load (more generally a force) applied to structural elements. [1] [2] A load causes stress, deformation, displacement or acceleration in a structure. Structural analysis, a discipline in engineering, analyzes the effects of loads on structures and structural elements.

  5. 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.

  6. 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, AIX, and Multics 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.

  7. 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.

  8. Bootloader - Wikipedia

    en.wikipedia.org/wiki/Bootloader

    In x86 computers, a first-stage bootloader is a compact 512-byte program that resides in the master boot record (MBR) and executes when a computer starts. Running in 16-bit real mode at address 0x7C00, it performs minimal hardware initialization, sets up a basic execution environment, and locates the second-stage bootloader.

  9. Process (computing) - Wikipedia

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

    The operating system keeps its processes separate and allocates the resources they need, so that they are less likely to interfere with each other and cause system failures (e.g., deadlock or thrashing). The operating system may also provide mechanisms for inter-process communication to enable processes to interact in safe and predictable ways.
