Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which bus architecture is most often seen in today’s high-speed video adapters?
A
ISA Express
B
PCI
C
AGP
D
PCI Express
Explanation: 

Detailed explanation-1: -Hardware and Software Compatibility PCI Express maintains software compatibility with traditional PCI but replaces the physical bus with a high-speed (2.5 Gb/s) serial bus. Because of this architecture change, the connectors themselves are not compatible.

Detailed explanation-2: -PCI operates at a maximum speed of 266 MBps at 66 MHz or 133 MBps at 33 MHz. This enclosure features a PCI Express (PCIe) x1 slot (v. 1.0) that operates at 250 MBps. The available bandwidth from the PCIe bus is split equally between the PCI slots, regardless of whether or not a card is inserted into each slot.

Detailed explanation-3: -Comparison of PCI and PCIe: PCI is a parallel interface whereas PCIe is a serial interface. PCI uses individual buses for each of the devices connected to it instead of a shared one like what PCIe uses. The difference in speed between standard PCI interface and 16 slot PCIe is large.

Detailed explanation-4: -The Peripheral Component Interconnect (PCI) bus is an expansion bus standard developed by Intel that became widespread around 1994. It was used to add expansion cards such as extra serial or USB ports, network interfaces, sound cards, modems, disk controllers, or video cards.
