USB enables you to charge your phone and any portable device with batteries to your computer or wall outlet. These devices store with a memory capacity designed to accommodate movies, songs, and other large files. Wireless file-sharing technologies may have become the norm, but USB flash drives are still everywhere because they remain reliable and portable. USB data-transfer rates are Low Speed, Full Speed, High Speed, SuperSpeed, and SuperSpeed+. The speed of transferring data between devices is the strongest suit of USB, whose theoretical transmission rate can reach up to 40 Gigabits per second. This ease of use is evident in hot swapping such that you can insert a peripheral into a USB port or remove it, for that matter, without turning off the computer or tweaking some settings. USB’s primary purpose is to connect devices to computers. Point of communication, plug and play.WHAT DOES A USB DO?įrom a then-struggling standard, USB has lived up to the universal in its name as millions, if not billions, of devices have adopted it. This technology is evolving to respond to ever-changing times, and you are on the right page. And because electronics that use USB run aplenty, learning more about the versions, types, and solutions is indispensable. Surely, you want to brush up on your knowledge about USB, the nitty-gritty of this handy, everyday technology from its history to terminology. Data storage, transmission, and portability have also received a boost from USB. There’s the standardization of ports replacing some, if not all, old computer sockets with a uniform one with supported cables and connectors. USB came along in the 1990s and changed computers and devices forever. Not all computer ports could run at once when in use under this scenario.

Data transfer also lagged with mere kilobytes per second although, between parallel and serial ports, parallel ports boasted faster transmission speed. For starters, peripherals might have been incompatible with the ports available. There were, however, problems with the usage of such legacy computer ports.

Under this setup, a keyboard, mouse, external monitor, printer, and all other PC accessories have a corresponding custom port to communicate with the computer. As you can see here, legacy serial and parallel ports once dominated the scene. The Universal Serial Bus has come a long way as a technology it is now a standard in today’s electronics and gadgets for work and play.Ĭomputers and peripherals interact through USB ports.
