Query

What port has 5 pins on the top and 4 on the bottom?

Output

That describes a **Serial Port**, specifically one using a **DE-9** (often commonly, though slightly inaccurately, called **DB9**) connector. * **Total Pins:** 9 * **Layout:** 5 pins on the top (wider) row, 4 pins on the bottom (narrower) row. * **Common Use:** Older peripherals like mice, modems, external devices, console connections for network gear, industrial equipment. It's easily confused with a VGA port, but VGA (DE-15) has 15 pins in three rows (5+5+5).
