Floppy drives connectors are very unique from any other connector inside of your computer. It has a 31 pin that sits on the twisted side of the connector cable with the non-twisted side fixed to the motherboard. It is a one-way connection and power component in that the connector side is a 4pin berg connector which is unique only to the floppy drive. Should you ever encounter a floppy drive whose light constantly eliminated and it doesn't read, chances are its cable is inverted with the twisted end sitting on the motherboard rather than on the floppy disk drive itself. USBs – universal serial bus – is the most commonly used connector and is used mostly for connecting to a keyboard, mouse, printer, or even mobiles devices. The USB comes in several types which denotes the differing speeds its available in. USB has a definitive symbol, so we'll diagram each show you how to identify the symbol, list the different transfer speeds for the standard USB, the Hi-Speed USB and the SuperSpeed USB. And we'll explain the differences between all the connectors that support them and how they are used.
