#Back panel connector definition how to
Still, Intel engineers figured out how to accomplish this goal using only copper wire. As that name suggests, Thunderbolt was initially intended to be a fiber-optic connection capable of 10Gbit/s (nearly twice the bandwidth of USB 3.0). Thunderbolt is a new type of connection that was developed by Intel under the codename Light Peak. Device manufacturers will have the option of offering Thunderbolt 3 inter-compatibility. USB 4.0, now officially known as USB4, is also on the horizon, and though it likely won’t be any faster than USB 3.2 2×2, it will unify standards to make the naming scheme less confusing and improve device compatibility. USB is entirely backward compatible, but you’re limited by the speed of the oldest generation in the chain of devices and connectors. You need to plug a compatible USB 3.x device into a compatible USB 3.x port to take full advantage of its generational speeds. USB 3.1 (officially USB 3.2 Gen 2) is faster still, operating at up to 10Gbps, while USB 3.2 (officially 3.2 Gen 2×2) can operate at up to 20Gbps in select circumstances. USB 3.2 Gen 1 ports can operate at up to 5,000Mbps, or 5Gbps.
USB 3.0 ports, officially now known as USB 3.2 gen 1 ( we know, it’s confusing), are often USB-A type and are blue to make them more distinct from USB 2.0 and other ports. USB 2.0 is the slowest typically found today, at just 480Mbps. Both can operate at different speeds, depending on the generation of USB technology that they support. USB-A is the non-reversible, oblong connector with right-angle corners, while USB-C is the newer, reversible alternative with rounded corners. USB ports come in an array of shapes, though the most common are USB-A and USB-C. Only Thunderbolt may provide a serious challenge - but it’s years away from widespread adoption. It took well over a decade, but it happened.
The Universal Serial Bus (USB) would make a good role model for supervillains everywhere.
