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.
Most functionality provided by PC Card or ExpressCard devices is now available as an external USB device. These USB devices have the advantage of being compatible with desktop computers as well as portable devices. (Desktop computers were rarely fitted with a PC Card or ExpressCard slot.)
USB 3.0 port provided by an ExpressCard-to-USB 3.0 adapter may be connected to a separately-powered USB 3.0 hub, with external devices connected to that USB 3.0 hub. On the motherboards of desktop PCs which have PCI Express (PCIe) slots (or the older PCI standard), USB 3.0 support can be added as a PCI Express expansion card.
Thunderbolt is the brand name of a hardware interface for the connection of external peripherals to a computer.It was developed by Intel in collaboration with Apple. [7] [8] It was initially marketed under the name Light Peak, and first sold as part of an end-user product on 24 February 2011.
A parallel port implemented as a PCI card.Users can use expansion cards to add deprecated legacy ports to newer computer systems that do not provide them. In computing, a legacy port is a computer port or connector that is considered by some to be fully or partially superseded. [1]
The USB 3.2 specification [7] added a second lane to the Enhanced SuperSpeed System besides other enhancements so that the SuperSpeedPlus USB system part implements the Gen 1×2, Gen 2×1, and Gen 2×2 operation modes. However, the SuperSpeed USB part of the system still implements the one-lane Gen 1×1 operation mode.
The Personal Computer Memory Card International Association (PCMCIA) was an industry consortium of computer hardware manufacturers from 1989 to 2009. Starting with the PCMCIA card in 1990 (the name later simplified to PC Card ), it created various standards for peripheral interfaces designed for laptop computers.
A typical 32-bit, 5 V-only PCI card, in this case, a SCSI adapter from Adaptec A motherboard with two 32-bit PCI slots and two sizes of PCI Express slots. Work on PCI began at the Intel Architecture Labs (IAL, also Architecture Development Lab) c. 1990. A team of primarily IAL engineers defined the architecture and developed a proof of concept ...
