A port expander is a device that allows one port on a computer system to connect to multiple devices. Two basic forms of port expander exist: internal and external. An internal expander has a connection inside the computer, typically on the motherboard, and the only part the user sees is the expansion plate containing multiple ports.
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 ...
A computer port is a hardware piece on a computer where an electrical connector can be plugged to link the device to external devices, such as another computer, a peripheral device or network equipment. [1] This is a non-standard term.
ExpressCard, initially called NEWCARD, [1] is an interface to connect peripheral devices to a computer, usually a laptop computer.The ExpressCard technical standard specifies the design of slots built into the computer and of expansion cards to insert in the slots.
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.
Accelerated Graphics Port (AGP) is a parallel expansion card standard, designed for attaching a video card to a computer system to assist in the acceleration of 3D computer graphics. It was originally designed as a successor to PCI -type connections for video cards.
F_Port (Fabric port) An F_Port is a switch port that is connected to an N_Port. [14] E_Port (Expansion port) Switch port that attaches to another E_Port to create an Inter-Switch Link. [14] Fibre Channel Loop protocols create multiple types of Loop Ports:
A riser card inside an IBM PS/2, featuring MCA slots Motherboard of an IBM PS/ValuePoint personal computer model (c. from 1993 to 1995) with an Intel i486SX microprocessor, with an elongated connector (black, horizontally in the middle/left between upper and lower edge) for the riser card on which the ISA bus slots were located
