New cards that support PCIe 2.0 are backward compatible with PCIe 1.1, thus you can install latest PCIe 2.0 cards on x16 PCIe slot of current or older motherboards. Latest PCIe 2.0 standards offer double the bandwidth of current PCIe 1.1 standards. The majority of single graphics cards are yet fast enough to fully take advantage of the wider bandwidth of PCIe 2.0. It is the multi-GPU or the multi-card set up that benefit most from PCIe 2.0. PCIe 2.0 and PCIe 1.1 use the x16 PCIe slot format but the PCIe 2.0 slot is capable of sustaining 150 watts while the PCIe 1.1 slot is only capable of 75 watts max. PCIe 3.0 is electrically compatible with previous generations but uses a different encoding scheme to increase the throughput.

yes it does

A person should install a PCIe network adapter in the PCIe network slot on a pc. The PCIE network adapter allows the PC the ability to connect with the Internet.
PCIe Version 1.1 and PCIe Version 1 have the same throughput.

I presume that you mean to ask whether a PCIe 3.0 card can be used in a PCIe 2.0 slot on your motherboard. The answer to that question is yes. PCIe standards are all backward-compatible, so do not sweat that. For best performance, however, you would prefer to put a PCIe 3.0 card in the same type of slot.
