Question

explain the difference between a serial ,a parallel and a usb port

Answer 1

Answer:

The main difference between a serial port and a parallel port is that a serial port transmits data one bit after another, while a parallel port transmits all 8 bits of a byte in parallel. Computers have both serial and parallel ports along with newer technology called a USB (Universal Serial Bus) port.
