  2. Central processing unit - Wikipedia

    en.wikipedia.org/wiki/Central_processing_unit

    Inside of a laptop, with the CPU removed from socket. Since microprocessors were first introduced they have almost completely overtaken all other central processing unit implementation methods. The first commercially available microprocessor, made in 1971, was the Intel 4004, and the first widely used microprocessor, made in 1974, was the Intel ...

  3. CPU cache - Wikipedia

    en.wikipedia.org/wiki/CPU_cache

    A CPU cache is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory. [1] A cache is a smaller, faster memory, located closer to a processor core, which stores copies of the data from frequently used main memory locations.

  4. Computer hardware - Wikipedia

    en.wikipedia.org/wiki/Computer_hardware

    Computer hardware includes the physical parts of a computer, such as the central processing unit (CPU), random access memory (RAM), motherboard, computer data storage, graphics card, sound card, and computer case.

  5. Platform Controller Hub - Wikipedia

    en.wikipedia.org/wiki/Platform_Controller_Hub

    Technically the processor can operate without a chipset; it only continues to be present for interfacing with low speed I/O. [8] AMD server and laptop CPUs adopt a self contained system on chip (SoC) design instead which doesn't require a chipset. [9] [10] [11]

  6. Processor register - Wikipedia

    en.wikipedia.org/wiki/Processor_register

    A processor register is a quickly accessible location available to a computer's processor. [1] Registers usually consist of a small amount of fast storage , although some registers have specific hardware functions, and may be read-only or write-only.

  7. Southbridge (computing) - Wikipedia

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

    At Intel, the authors of the PCI specification viewed the PCI local bus as being at the very centre of the PC platform architecture (i.e., at the Equator). The northbridge extends to the north of the PCI bus backbone in support of CPU, memory/cache, and other performance-critical capabilities. Likewise the southbridge extends to the south of ...

  8. 64-bit computing - Wikipedia

    en.wikipedia.org/wiki/64-bit_computing

    In computer architecture, 64-bit integers, memory addresses, or other data units [a] are those that are 64 bits wide. Also, 64-bit central processing units (CPU) and arithmetic logic units (ALU) are those that are based on processor registers, address buses, or data buses of that size. A computer that uses such a processor is a 64-bit computer.
