It's not exactly the same thing is all I was pointing out, I couldn't imagine people still used those old serial ports.
Actually, it is exactly correct. USB has 4 connections. That would be 1RX 1TX power and ground. A wire can transmit 1 bit at a time. Guess what? We call that "Serial".

Serial always means bit at a time. SATA interfaces? One bit at a time. PATA? 8 (or 16 for wide pata) at a time. FireWire? 1 bit at a time.

Anything using 1 wire to transmit data is serial. Even if its really really fast, it's pushing 1 bit at a time.
