This is a partial list of expansion bus interfaces, or expansion card slots, for installation of expansion cards. Bus interfaces. Interface name Year introduced
In computing, an expansion card (also called an expansion board, adapter card, peripheral card or accessory card) is a printed circuit board that can be inserted into an electrical connector, or expansion slot (also referred to as a bus slot) on a computer's motherboard (see also backplane) to add functionality to a computer system. Sometimes ...
Two types of DIMMs (dual in-line memory modules): a 168-pin SDRAM module (top) and a 184-pin DDR SDRAM module (bottom). Memory modules of SK Hynix. In computing, a memory module or RAM stick is a printed circuit board on which memory integrated circuits are mounted.
Originally developed by the Personal Computer Memory Card International Association (), the ExpressCard standard is maintained by the USB Implementers Forum ().The host device supports PCI Express, USB 2.0 (including Hi-Speed), and USB 3.0 (SuperSpeed) [2] (ExpressCard 2.0 only) connectivity through the ExpressCard slot; cards can be designed to use any of these modes.
An option ROM for the PC platform (i.e. the IBM PC and derived successor computer systems) is a piece of firmware that resides in ROM on an expansion card (or stored along with the main system BIOS), which gets executed to initialize the device and (optionally) add support for the device to the BIOS.
The PCI-X standard was developed jointly by IBM, HP, and Compaq and submitted for approval in 1998. It was an effort to codify proprietary server extensions to the PCI local bus to address several shortcomings in PCI, and increase performance of high bandwidth devices, such as Gigabit Ethernet, Fibre Channel, and Ultra3 SCSI cards, and allow processors to be interconnected in clusters.
The computer sends and receives data via an input/output device; examples: storage device (such as disk drive, solid-state drive, USB flash drive, memory card and tape drive), modem, router, gateway and network adapter
In particular, PCI Express expansion cards take much of their power from the 12 V rail (up to 5.5 A), while the older AGP graphics cards took only up to 1 A on 12 V and up to 6 A on 3.3 V. The CPU is also driven by a 12 V rail, while it was done by a 5 V rail on older PCs (before the Pentium 4).
