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. Devices connected to the PCI bus appear ...
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 ...
BIOS interrupt calls perform hardware control or I/O functions requested by a program, return system information to the program, or do both. A key element of the purpose of BIOS calls is abstraction - the BIOS calls perform generally defined functions, and the specific details of how those functions are executed on the particular hardware of the system are encapsulated in the BIOS and hidden ...
Contrary to its predecessor BIOS which is a de facto standard originally created by IBM as proprietary software, UEFI is an open standard maintained by an industry consortium. Intel developed the original Extensible Firmware Interface (EFI) specification. The last Intel version of EFI was 1.10 released in 2005.
A software protection dongle (commonly known as a dongle or key) is an electronic copy protection and content protection device. When connected to a computer or other electronics, they unlock software functionality or decode content. [1] The hardware key is programmed with a product key or other cryptographic protection mechanism and functions ...

Input/output. v. t. e. In the context of an operating system, a device driver is a computer program that operates or controls a particular type of device that is attached to a computer or automaton. [ 1 ] A driver provides a software interface to hardware devices, enabling operating systems and other computer programs to access hardware ...
In data networking and transmission, 64b/66b is a line code that transforms 64- bit data to 66-bit line code to provide enough state changes to allow reasonable clock recovery and alignment of the data stream at the receiver. It was defined by the IEEE 802.3 working group as part of the IEEE 802.3ae-2002 amendment which introduced 10 Gbit/s ...
