A brief history of USB
by Andrew Cunningham, ars technica
USB isn’t perfect, but it replaced lots of ports we’ll never have to see again
Like all technology, USB has evolved over time. Despite being a “Universal” Serial Bus, in its 18-or-so years on the market it has spawned multiple versions with different connection speeds and many, many types of cables.
The USB Implementers Forum, the group of companies that oversees the standard, is fully cognizant of this problem, which it wants to solve with a new type of cable dubbed Type-C. This plug is designed to replace USB Type-A and Type-B ports of all sizes on phones, tablets, computers, and other peripherals. Type-C will support the new, faster 10Gbps USB 3.1 gen 2 spec with room to grow beyond that as bandwidth increases.
