  2. Key Code Qualifier - Wikipedia

    en.wikipedia.org/wiki/Key_Code_Qualifier

    Key Code Qualifier is an error-code returned by a SCSI device. When a SCSI target device returns a check condition in response to a command, the initiator usually then issues a SCSI Request Sense command. This process is part of a SCSI protocol called Contingent Allegiance Condition.

  3. Radio Interface Layer - Wikipedia

    en.wikipedia.org/wiki/Radio_Interface_Layer

    A RIL is a key component of Microsoft's Windows Mobile OS. The RIL enables wireless voice or data applications to communicate with a GSM/GPRS or CDMA2000 1X modem on a Windows Mobile device. The RIL provides the system interface between the CellCore layer within the Windows Mobile OS and the radio protocol stack used by the wireless modem hardware.

  4. Error recovery control - Wikipedia

    en.wikipedia.org/wiki/Error_recovery_control

    Modern hard drives feature an ability to recover from some read/write errors by internally remapping sectors and performing other forms of self-test and recovery. The process for this can sometimes take several seconds or (under heavy usage) minutes, during which time the drive is unresponsive.

    initialize, size, and verify system main memory; initialize BIOS; pass control to other specialized extension BIOSes (if installed) identify, organize, and select which devices are available for booting; The functions above are served by the POST in all BIOS versions back to the very first. In later BIOS versions, POST will also: initialize chipset

    en.wikipedia.org/wiki/Fill_device

    A fill device or key loader is a module used to load cryptographic keys into electronic encryption machines. Fill devices are usually hand held and electronic ones are battery operated. Older mechanical encryption systems, such as rotor machines, were keyed by setting the positions of wheels and plugs from a printed keying list. Electronic ...

    seed key - (NSA) a key used to initialize a cryptographic device so it can accept operational keys using benign transfer techniques. Also a key used to initialize a pseudorandom number generator to generate other keys. signature key - public key cryptography can also be used to electronically sign messages. The private key is used to create the ...

  8. Error correction code - Wikipedia

    en.wikipedia.org/wiki/Error_correction_code

    Low-density parity-check (LDPC) codes are a class of highly efficient linear block codes made from many single parity check (SPC) codes. They can provide performance very close to the channel capacity (the theoretical maximum) using an iterated soft-decision decoding approach, at linear time complexity in terms of their block length.

  9. UEFI Platform Initialization - Wikipedia

    en.wikipedia.org/wiki/UEFI_Platform_Initialization

    The Platform Initialization Specification (PI Specification) is a specification published by the Unified EFI Forum that describes the internal interfaces between different parts of computer platform firmware. [1] This allows for more interoperability between firmware components from different sources.
