:::what is interrupt request, direct memory access, input/output range and memory range

These are the resources that the card is using to interface itself into the system hardware.

I will assume that you are not using all of your COM ports in the back of the system (D shaped 9, or 25 pin connectors) and you have a PS/2 style mouse (round connector similar to keyboard connector).  If this is the case, you can change the resources for one of the two COM ports to the same IRQ as the other COM port.  Then you can either change the sound card to use the newly freed IRQ (if it will) or move another device to that IRQ, and put the sound card at the one it was using.

Confused?  If so, let me know.

I've also seen sound cards work (and the printer as well) sharing the printer IRQ (LPT7)

I think I can answer part of your question.
Interupt Request is a term for cpu(central processing unit) to communicate with other computer hardware. A hardware (e.g. CDROM) wants to send signal to CPU, CDROM will generate an interupt request to CPU. CPU may stop its current job and handle the interupt.
IRQ tells the address for hardware

Value of IRQ of Sound card is usually 5.

Direct memory access(DMA) is a way for transfering data from a I/O(e.g. CROM, harddisk). DMA is usually for reading a large amount of data.

Value of DMA for sound card is 1.
