USB - Universal Serial Bus

USB is a relatively new kind of computer port that is poised to replace all the old ports. All new Mac computers only have USB ports. HP, TI and Casio Connectivity Cable for USB is available. TI´s newer model calculators have built in mini USB ports.

Short for Universal Serial Bus, an external bus standard that supports data transfer rates of 12 Mbps. A single USB port can be used to connect up to 127 peripheral devices, such as mice, modems, and keyboards. USB also supports Plug-and-Play installation and hot plugging. Starting in 1996, a few computer manufacturers started including USB support in their new machines. It wasn´t until the release of the best-selling iMac in 1998 that USB became widespread. It is expected to completely replace serial and parallel ports.
