A) ISA

B) AGP

C) PCI

D) PCI Express


Answer: C) PCI

The PCI (Peripheral Component Interconnect) architecture may not be one of the newest, but it certainly is one of the most popular adapter card architectures around. Most computers still include PCI slots alongside the similarly-named-but-not-compatible PCI Express slots.

The incorrect answers:
A) ISA
ISA (Industry Standard Architecture) is an older bus standard that’s usually only seen on legacy systems. It’s unlikely that you’ll find any new systems that support ISA, and locating any new ISA adapters cards for sale is just as unlikely.

B) AGP
AGP (Advanced Graphics Port) adapters were very popular before the introduction of PCI Express, but the use of AGP has slowly dwindled away. As the name implies, the AGP architecture was designed to provide high-speed access for graphics cards.

D) PCI Express
PCI Express (PCI-E or PCIe) is the latest in bus architectures, providing higher speeds than PCI or AGP. PCIe supports many different slots sizes, with the largest size slots supporting speeds of 500 megabytes per second.
