VGA

A VGA connector as it is commonly known (other names include RGB connector, D-sub 15, mini sub D15 and mini D15) is a three-row 15 pin DE-15. There are four versions: original and DDC2 pinouts, the far older and less flexible DE-9 connector, and a Mini-VGA used for laptops.
The common 15-pin VGA connector found on most video cards, computer monitors, and other devices, is almost universally called "HD-15". HD stands for "high-density", which distinguishes it from connectors having the same form factor but only 2 rows of pins. However, this connector is often incorrectly referred to as a DB-15 or HDB-15.[citation needed]
"VGA connectors" and their associated cabling are almost always used solely to carry analog component RGBHV (red - green - blue - horizontal sync - vertical sync) video signals along with DDC2 digital clock and data.
Where size is a constraint (such as laptops) a mini-VGA port can sometimes be found in place of the full-sized VGA connector.

USB 2.0 Typ-A

Der Universal Serial Bus (USB) ist ein serielles Bussystem zur Verbindung eines Computers mit externen Geräten. Mit USB ausgestattete Geräte oder Speichermedien können im laufenden Betrieb miteinander verbunden (Hot-Plugging) und angeschlossene Geräte sowie deren Eigenschaften automatisch erkannt werden.
USB eignet sich für viele Geräte wie Massenspeicher (etwa Festplatte, Diskette, DVD-Laufwerk), Drucker, Scanner, Webcams, Maus, Tastatur, aber auch Dongles und sogar Grafikkarten und Monitore.
