First i would install all the necesary drivers needed on the computer.
The unused ports on your Personal Computer are dependant on the types of ports available on the computer and the type of peripherals connected. A typical desktop computer could have the following ports occupied:VGA or DVI for displayEthernet for networkingUSB for most peripherals, such as keyboard, mouse, webcam, connection cables2.5mm jack for audioThe other ports would remain unused until something requiring them is connected, and they vary greatly depending on the type of 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.
Your computer might not necessarily have a com port at all. A com port is just an older style serial port. USB ports have replaced com ports for the most part. If you have any com ports, they would be on the back of the computer. They would be male (pins sticking out), and have 9 or 25 pins. If there is a 25-pin female D-socket, that would be a parallel port.
If you are refering to a port on a computer. There are usually other ports you can try to use instead. I have this problem on mine and the back ports in the back of the computer work fine. But the front do not. Otherwise you would need to take it and get it serviced.
You would want to use get a crossover cable.
It would most likely be located on the front of the computer for easy accessibility. Some cases have a sliding panel that may conceal front ports that are not being used.
Depends on the type of hub you're talking about. A USB expansion hub for example would allow for additional USB ports.
The processor would be considered to be the brain of the computer. RAM is just part of the working memory of the computer.
i believe it would be the computer.
It depends on the type of ports needed. If you need more USB sockets, you can simply plug a USB hub into a USB socket. However, if you need other types of ports (like display ports, network ports, 9 or 25-pin serial ports, SATA sockets etc)., or you don't want to use a USB hub, then you would have to install an expansion card.
And what, exactly, would you connect them to on your computer? You can get a hub to extend existing USB 2.0 ports, but there are no external buses with enough bandwidth to install a USB 2.0 controller.
