USB started with a data rate of 1.5Mb/s and 12Mb/s In "Low Speed" and "Full Speed" variants, rates which were blisteringly fast at the time of its release, though the "Full Speed" version USB also enabled power to be provided to the device at the same time as power, which helped cut down on the number of cables a user needed to manage in their setup. For the most part, this involved a connector known as USB Type-A being plugged into computers, which we will discuss later. Right port on their computer, or even having to find the right cable. This reliance on a small selection of robust connectors meant it was easier for users to manage multiple devices, without having to worry about running out of ports, struggling to find the Type of connector and the wires within a cable in a specific prescribed way, and that would be largely the same across the board, with relatively few exceptions. The aim of USB was to create a standard that would work across multiple different devices, unifying the myriad of technologies down to one, as the name suggests.

Originally released in 1996, the USB (Universal Serial Bus) standard is the older of the two connection types, created by a group of companies including IBM, Microsoft, Intel, and others,Īnd maintained by the USB Implementers Forum. If you don't read any further, here's your main takeaway: The term "USB-C" by itself doesn't specify anything for data, charging, or video beyond the physicality of the connector. But,Īs you might expect, there are a lot of details behind USB 3, USB 4, Thunderbolt 3, Thunderbolt 4, and how they pertain to the USB-C connector. The two technology trees are, largely, quite different.
Both have their benefits and their foibles, as well as sharing many characteristics, but Here's what you need to know about USB 3, USB 4, Thunderbolt 3, and Thunderbolt 4.įor most users, there are two general families of multi-purpose connections: USB and Thunderbolt. With the varieties of USB and Thunderbolt terminology floating about, as well as new versions on the horizon, sorting
