[edit] 8P8C connector
8P8C is short for "eight positions, eight conductors", and so an 8P8C modular connector (plug or jack) is a modular connector with eight positions, all containing conductors. The 8P8C modular plugs and jacks look very similar to the plugs and jacks used for FCC's registered jack RJ45 variants, although the true and extremely uncommon RJ45 is not really compatible with 8P8C modular connectors. It neither uses all eight conductors (but only two of them for wires plus two for shorting a programming resistor) nor does it fit into 8P8C because the true RJ45 is "keyed". The connector is probably most famous for its use in Ethernet and widely used on CAT5 cables.
[edit] DE-9 connector
The DE-9 (9 pin D-shell connector) is a type of D-subminiature electrical connector most commonly used for the RS 232 serial port on the IBM AT and compatible computers. DB-9 is a common misnomer for the DE-9. (A true DB-9 connector would have 9 pins in a connector the shape and size of a DB-25, the other 16 pins would just be missing.) The DE-9 connector is used in many different applications, for computers, telecommunications, and test and measurement instruments. A few examples are older monitors (MGA, CGA, EGA), the Commodore 64, MSX, Apple II, Amiga and Arati joysticks and mouses, and game consoles such as Atari, Sega and Amiga.
[edit] USB connectors
The Universal Serial Bus is a serial bus standard to interface devices, founded in 1996. It is currently widely used among PCs, Apple Macintosh and many other devices. There are several types of USB connectors, and some have been added as the specification has progressed. The most commonly used is the (male) series "A" plug on peripherals. It is a 4-pin connector, surrounded by a shield. There are several other connectors in use, such as the series "B" plug, the Mini-B plug (added in USB 2.0), the mini-A and mini-AB plug (Added in the On-The-Go Supplement to the USB 2.0 Specification).
