Motherboard slots.

There's a list of motherboards I've seen searching on newegg with slots such as 64-bit/100MHz PCI-X. What is the use of this slot? What is the use of PCI 1x slots, and why do the new boards with PCI 16x have them? The only use I've seen of the 1x slots is an old AOpen 56K modem in my cousin's obsolete computer. Also, what does Dual-Channel Memory actually do for you?
 
memory runs 128bit instead of 64bit. Though u must have matched pairs of ram in most cases to run dual channel.(nforce 3 will run up to 3 sticks in DC. Said to be faster than single channel 🙂 of course. Heard of some people having problems with it but I never have. Usually the mem slots on the board are color coded for dual channel.
 
The very short slots are the PCIx1. The longer ones, usually at the bottom of the motherboard are regular PCI. Still sure your card's going in a PCIx1 slot??

PCI-E has only been around for a bit over a year so I guarantee that really old modem isn't a PCI-E 1x. It is likely a CNR and would look something like THIS
PCI-E intends to replace PCI, so all adapter cards available for PCI should someday be available for PCI-E. For this reason, x1 slots are provided on PCI-E motherboards.

PCI-X is available in 64bit and up to 133MHz. It is backwards compatible with PCI. It is mainly used for storage adapters... i.e. RAID and/or SCSI controllers. For a desktop computer you have little or no use for PCI-X.
