usb: universal serial bus
USB ports were common among computers ever since they were created. When USBs were made into storage devices, external data storage once again stepped up in terms of sturdiness, capacity and size. The USB erased the problem of the size of optical discs as they became the smallest external storage device ever created. With a weight on average of 30g, the size and weight of the USB made it simple to carry and very light.
USBs also carries a large capacity of an average of 2 GB making it better in comparison to size of CDs and DVDs. They can support anything from documents to music or videos to software. Computers recognise USBs and can open and write on them in a matter of milliseconds, making it the quickest external storage device. All these great features make the USB the easiest and most used external storage device in the world.
