Yes, most motherboards these days have connections for at LEAST four USB 2.0 devices. In addition to this, USB is a scalable connection so using hubs it's possible to connect up to 255 devices to one USB port (realistically the performance will be terrible, so you should limit yourself to about 10 per port). So yes, you can easily have that many ports off one system.
Companies make 4 port, 7 port and even as high as 40 port USB hubs.
NoYou can open the computer up and remove the USB ports.
There's no possible answer to that. A computer can have any number of USB ports. As the above is true, it doesn't matter how many you use. You can use as much USB ports as you want on your computer.
One way to add USB ports to a computer you need a USB expansion card that you add to the motherboard. The card usually has multiple USB ports built into them.
A Computer Bus is usually the USB Ports, and there used for USB Plugging things.
It is an extra set of USB ports for a computer.
if the Dell computer has USB ports, then all you would need is the USB-iPod cable and download/install iTunes. If you system is really old and only have serial ports (9-pin male ports) and no USB ports, then you would need to get a PCI USB card installed into your system. Do not use Serial-USB adapters, as they do not always work.
Maybe linking it to a computer =P
Turn the computer around.
It all depends on how many USB Ports are on your computer. If you count them up, then you have your answer.
The only parallel to USB adapter I've seen is one which allows you to hook up a parallel printer to a USB port on the computer. You could not use that manner to create USB ports.
No. When you update the USB Host, it updates all the 'ports'. Actually, the physical ports are just places to plug things in. The updating actually happens with the software hardcoded into the USB Root Hub, which controls all the ports.
A root hub is the socket on a computer's system board to which its USB ports are connected. A computer may have more than one USB root hub.
