Common ports provided by most motherboards are as follows.
Serial port (RS-232)
Ethernet Port (Network interface)
Parallel port. (Not nearly as common any longer)
PS/2 Port (Mice and Keyboards)
USB Ports (Covers most everything these days)
Firewire port (IEEE1394, mostly used for video these days)
eSATA Port (External Hard drive or device interface).
There are others, but those are your most common ports on standard desktop motherboards. Servers are another story.
I/O controller
Input/Output Controller Card
It depends on the motherboard, and built-in devices. You might have to change the sound card, or the display adapter
That means that you're using a USB to Serial adapter like this: http://sewelldirect.com/usbtoserial.asp Prolific is one of the companies that makes USB to Serial chipsets, and when you are using one of their adapters it will show up on your computer like that. Many newer computer do not have serial ports on them so you need a USB to Serial adapter to be able to use serial devices with your computer. If you have a laptop and you're using a docking station then it might have a USB to Serial adapter inside of it which is using the Prolific chipset.
You might be able to solve a problem with a notebook that has an unstable system or a motherboard component by?
Because you might drop the drives on your motherboard while installing.
Drivers, sometimes installation.
Without knowing what particular motherboard model you have, there is no way of answering that. The board might support higher, it might be maxed out, or the processor might even be soldered on! THIS IS ALL WRONG!! YO MAMA~!
PCI (Peripheral Component Interconnect) PCI Express SATA (Serial Advanced Technology Attachment) ATA ( Advanced Technology Attachment - also called IDE - Integrated Drive Electronics) FireWire (IEEE 1394) USB (Universal Serial Bus)
That appliance might last longer if you use an eight volt adapter rather than a nine volt adapter.
Most adapters have a self-diagnostic feature. You might find it, if you click on the adapter in your device manager.
Perhaps, because there might be not enough place after you install the motherboard to install your drives. The CPU or the RAMs might be in they way. There is surely no other magical reason to it.
