What port has 5 pins on the top and 4 on the bottom?
What port has 5 pins on the top and 4 on the bottom?
The port that has 5 pins on the top row and 4 pins on the bottom row is the DB-9 (or DE-9) serial port. This is a D-subminiature connector commonly used for RS-232 serial communications on older computers and equipment. These ports were widely used before USB became standard, and were typically found on: - Older computers for connecting modems - Serial mice and other peripheral devices - Industrial equipment and control systems - Some networking equipment While less common today, DB-9 serial ports are still used in industrial applications, legacy systems, and some specialized equipment.

What port has 5 pins on the top and 4 on the bottom?
The port that has 5 pins on the top row and 4 pins on the bottom row is a DE-9 connector (sometimes incorrectly called DB-9), which is commonly used for RS-232 serial connections. This D-shaped connector was very common on older computers for connecting devices like: - Mice (before PS/2 and USB) - Modems - Serial printers - Terminal equipment While less common on modern consumer computers, these 9-pin serial ports are still widely used in industrial equipment, networking devices, and specialized applications where legacy compatibility or simple serial communication is needed.
