The correct answer is: A. Serial device.
A 15-pin female connector with the pins in two rows is a standard connector for serial devices. Serial devices are devices that communicate with a computer one bit at a time, in a serial stream. This type of connection is slower than parallel connections, but it is more reliable and can be used over longer distances.
Some examples of serial devices include:
- Modems
- Mice
- Printers
- Scanners
Parallel devices, on the other hand, communicate with a computer eight bits at a time, in a parallel stream. This type of connection is faster than serial connections, but it is less reliable and can only be used over short distances.
Some examples of parallel devices include:
- Printers
- Scanners
- Plotters
MIDI devices are musical instruments that communicate with a computer using the MIDI protocol. MIDI is a standard protocol for communicating with musical instruments. It allows the computer to control the instrument and the instrument to send data to the computer.
Video devices are devices that output video signals to a computer monitor or television. Some examples of video devices include:
- Graphics cards
- Video capture cards
- TV tuner cards
Joysticks are input devices that are used to control games and other applications. They typically have a stick that can be moved in all directions and a button that can be pressed.
