    en.wikipedia.org/wiki/Symmetric_multiprocessing

    Diagram of a symmetric multiprocessing system. Symmetric multiprocessing or shared-memory multiprocessing [1] (SMP) involves a multiprocessor computer hardware and software architecture where two or more identical processors are connected to a single, shared main memory, have full access to all input and output devices, and are controlled by a single operating system instance that treats all ...

    en.wikipedia.org/wiki/Power_supply_unit_(computer)

    Most modern desktop personal computer power supplies conform to the ATX specification, which includes form factor and voltage tolerances. While an ATX power supply is connected to the mains supply, it always provides a 5- volt standby (5VSB) power so that the standby functions on the computer and certain peripherals are powered.

    en.wikipedia.org/wiki/Uninterruptible_power_supply

    A large data-center-scale UPS being installed by electricians. An uninterruptible power supply (UPS) or uninterruptible power source is a type of continual power system that provides automated backup electric power to a load when the input power source or mains power fails.

  9. Uniform memory access - Wikipedia

    en.wikipedia.org/wiki/Uniform_memory_access

    Uniform memory access (UMA) is a shared memory architecture used in parallel computers.All the processors in the UMA model share the physical memory uniformly. In an UMA architecture, access time to a memory location is independent of which processor makes the request or which memory chip contains the transferred data.
