Mice, keyboards, and cameras and video cameras,
I don't know about fivewire ports but if you mean FireWire: FireWire ports are used by many video cameras and are commonly seen on Macintosh computers, however they are also seen on PCs.
Most commonly, USB and Firewire. Though there are lots of different ways to do it, these are by far the most common.
Firewire and parallel are not mouse connection ports.
The PS/2 ports connect a mouse and keyboard, while the game port connects game controllers. Parallel and serial ports connect older printers and PDA devices. Most current input devices use the USB port, of which there are usually several available on a modern computer. Firewire ports connect high-speed devices, including DV cameras and Firewire hard drives. Another high-speed hard drive connector is the eSATA port.

It depends what you mean by popular and who you are asking. The most commonly used connector is the USB port. If someone recorded a lot of video on a camera with a FireWire connection then the FireWire port would be quite popular with them.
USB and FireWire
no
No. If they were, we wouldn't have replaced them. USB and FireWire are over 3000 times faster with the latest revisions.
eSATA is faster than FireWire and firewire is faster than USB.
External Hard Drives are generally connected to USB ports or FireWire ports.
The older ones do, but the very latest ones do not.
