    parallel file system

    A parallel file system is a software component designed to store data across multiple networked servers.

  • PCIe SSD (Peripheral Component Interconnect Express solid-state drive)

    A PCIe SSD (Peripheral Component Interconnect Express solid-state drive) is a high-speed expansion card that attaches a computer to its peripherals.

  • pebibyte (PiB)

    A pebibyte (PiB) is a unit of measure that describes data capacity.

  • persistent storage

    Persistent storage is any data storage device that retains data after power to that device is shut off.

  • petabyte

    A petabyte is a measure of memory or data storage capacity that is equal to 2 to the 50th power of bytes.

  • primary storage (main storage)

    Primary storage is the collective methods and technologies that capture and retain digital information in active use and critical for an organization's operations.

  • program/erase cycle (P/E cycle)

    A solid-state storage program/erase cycle (P/E cycle) is a sequence of events in which data is written to a solid-state NAND flash memory cell, such as the type found in a flash or thumb drive, and is subsequently erased and rewritten.

  • protected mode

    Protected mode, also called protected virtual address mode, is the primary mode of operation for an Intel-based x86 microprocessor.

  • public cloud storage

    Public cloud storage, also called online storage, is a service model that provides data storage on a pay-per-use basis.

  • Pure Storage

    Pure Storage is a provider of enterprise data flash storage products designed to substitute for electromechanical disk arrays.

  • software portability

    Software portability is a characteristic attributed to a computer program if it can run with minimal rework on operating systems (OSes) other than the one for which it was created.

  • What is a partition in computers?

    A partition is a logical division of a hard disk drive (HDD) that's treated as a separate unit by operating systems (OSes) and file systems.

  • What is parity in computing?

    In computers, parity (from the Latin paritas, meaning "equal or equivalent") is a technique that checks whether data has been lost or written over when it is moved from one place in storage to another or when it is transmitted between computers.

  • What is pay-as-you-go cloud computing (PAYG cloud computing)?

    Pay-as-you-go cloud computing, or PAYG cloud computing, is a payment method for cloud computing that charges based on usage. The practice is similar to that of utility bills, using only resources that are needed.

  • What is personal cloud storage (PCS)?

    Personal cloud storage (PCS) is a local network-attached storage (NAS) device that lets users store data, photos, music, videos and other files and is optimized for media streaming.
