Question

Which is the most common expansion slot found in PCs?

a) PCI Express (PCIe)
b) ISA
c) AGP
d) VESA Local Bus (VLB)

Answer 1

The most common expansion slot in modern PCs is the PCI Express (PCIe) slot, surpassing older slots like ISA, AGP, and VLB with its improved speed and versatility.

Step-by-step explanation:

The most common expansion slot found in modern personal computers is the PCI Express (PCIe) slot. This type of slot has largely replaced older standards such as ISA, AGP, and VESA Local Bus (VLB) due to its greater speed and flexibility. After its initial release in 2003, PCIe has undergone several iterations, with PCIe 4.0 and even PCIe 5.0 providing significant improvements in terms of bandwidth and performance over the original PCIe standard.

PCIe slots are used for a wide range of purposes, such as connecting graphics cards, SSDs, network cards, and many other types of peripherals and expansion cards. The PCIe standard aligns with the continuous demand for higher data transfer rates and the need for greater bandwidth to accommodate the needs of modern computing applications and devices.
