  2. PCI configuration space - Wikipedia

    en.wikipedia.org/wiki/PCI_configuration_space

    One of the major improvements the PCI Local Bus had over other I/O architectures was its configuration mechanism. In addition to the normal memory-mapped and I/O port spaces, each device function on the bus has a configuration space, which is 256 bytes long, addressable by knowing the eight-bit PCI bus, five-bit device, and three-bit function numbers for the device (commonly referred to as the ...

  3. Type Allocation Code - Wikipedia

    en.wikipedia.org/wiki/Type_Allocation_Code

    The Type Allocation Code (TAC) is the initial eight-digit portion of the 15-digit IMEI and 16-digit IMEISV codes used to uniquely identify wireless devices.. The Type Allocation Code identifies a particular model (and often revision) of wireless telephone for use on a GSM, UMTS, LTE, 5G NR, iDEN, Iridium or other IMEI-employing wireless network.

  4. GSM Cell ID - Wikipedia

    en.wikipedia.org/wiki/GSM_Cell_ID

    values 1, 2, and 3 are used to identify sectors of bisector or trisector antennas. In UMTS, there is a distinction between Cell ID (CID) and UTRAN Cell ID (also called LCID). The UTRAN Cell ID (LCID) is a concatenation of the RNC-ID (12 bits, ID of the Radio Network Controller ) and Cell ID (16 bits, unique ID of the Cell).

  5. Cell Global Identity - Wikipedia

    en.wikipedia.org/wiki/Cell_Global_Identity

    Cell Global Identity (CGI) is a globally unique identifier for a Base Transceiver Station in mobile phone networks. [1] It consists of four parts: Mobile Country Code (MCC), Mobile Network Code (MNC), Location Area Code (LAC) and Cell Identification (CI).

  6. Peripheral Component Interconnect - Wikipedia

    en.wikipedia.org/wiki/Peripheral_Component...

    Peripheral Component Interconnect (PCI) [3] is a local computer bus for attaching hardware devices in a computer and is part of the PCI Local Bus standard. The PCI bus supports the functions found on a processor bus but in a standardized format that is independent of any given processor's native bus.

  7. Vital Product Data - Wikipedia

    en.wikipedia.org/wiki/Vital_Product_Data

    Vital Product Data (VPD) is a collection of configuration and informational data associated with a particular set of hardware or software. [1] VPD stores information such as part numbers, serial numbers, and engineering change levels. Not all devices attached to a system will provide VPD, but it is often available from PCI and SCSI devices.

  8. Protocol-control information - Wikipedia

    en.wikipedia.org/wiki/Protocol-control_information

    In telecommunications, the term protocol-control information (PCI) has the following meanings: [1] [2] [3] [4]. The queries and replies among communications equipment ...

  9. Message Signaled Interrupts - Wikipedia

    en.wikipedia.org/wiki/Message_Signaled_Interrupts

    MSI (first defined in PCI 2.2) permits a device to allocate 1, 2, 4, 8, 16 or 32 interrupts. The device is programmed with an address to write to (this address is generally a control register in an interrupt controller), and a 16-bit data word to identify it. The interrupt number is added to the data word to identify the interrupt. [1]
