Does somebody know about ports and especialy about so called COMM port? When is it used and in which way is it different from other ports? Thanks!

The COM port is a serial data port adhering to an ANSI standard called RS-232C.  Most PCs have at least one of these and often two.  They are used to communicate with devices that use this interface.  Most common here are:

1) Printers
2) External Modems and ISDN adapters
3) Mice (although the PS/2 style mouse is now dominant)

But, in fact, there are 100s of different peripheral devices that connect to serial or COM ports.

Thanks jhance!
Can you also tell me if this port is appropriate for receiving signals from external UV-detector, for example or from some other detectors in chemical analyses?
Commented:
Yes.  That would be the main purpose of COM ports - communication.  I used to work at a laboratoey and they had many pieces of equipment sending data to computers through COM ports.  Some also had special interface boards, though.
