    That isn't a function of the Cat5 cable as much as it is the TCP/IP protocol that is transmitted over the cable. The cable transmits digital signals which aren't much different from morse code. It's just on or off, one or zero, dot or dash. It's the function of the TCP/IP stack to keep track of the various sessions and applications that are simultaneously sending streams of ones and zeros over the physical cable. It doesn't matter if it's wireless or fiber optic. I'd suggest reading a good rudimentary networking book. Michael Meyers's Network+ Certification All-in-One Exam Guide is a good start. From there you can glean much more infromation from places like wikipedia. If you really want to go in deep, read The TCP/IP Guide. And if that's not deep enough, you can go positively subteranean with TCP/IP Illustrated Vols 1 - 3.
