Final answer:
PCIe offers higher data transfer rates and is a more modern interface than conventional PCI, which is older and not interchangeable with PCIe.
Step-by-step explanation:
Regarding PCI (Peripheral Component Interconnect) and PCI Express (PCIe), the two true statements are:
- PCIe offers higher data transfer rates than conventional PCI.
- Conventional PCI is older than PCIe.
Conventional PCI slots and PCIe slots are not interchangeable - they have different physical configurations, protocols, and purposes. While conventional PCI was used in older systems for various types of expansion cards, PCIe has a serial interface with higher data transfer rates and is now the standard for connecting high-speed components such as graphics cards and solid-state drives.
