DTE devices in the sense we have PC (Computers), router,Serial Printers, PLC's, Video Cameras, Video Recorders, Video Editors like this we use any of them depending on our requirementDCE devices in the sense hub,bridge,switch,modem etc are dce devices we usei hope it is useful to you........
To configure the clock rate for the hardware connections on serial interfaces such as network interface modules (NIMs) and interface processors to an acceptable bit rate, use the clock rate interface configuration command. Use the no form of this command to remove the clock rate if you change the interface from a DCE to a DTE device. Using the no form of this command on a DCE interface sets the clock rate to the hardware-dependent default value.
When two routers are connected to communicate using a serial cable connection, one end of the router will be using DTE (Data Terminal Equipment) and the other end uses DCE (Data Communication Equipment). In order to communicate effectively with out any delay or to have the same band width, we use 64000 clock rate. This answer is given with the knowledge what I have, please update me if I am wrong. Thank you Syed

External modems are built with a female data communications equipment (DCE) DB-25 port for connection to a controlling device such as a PC or a router. Depending on the model of the router you are connecting to, you will use that type of cable. For details lookup "modem-router configuration" on cisco.com
To connect a PC to a switch you should use a straight through UTP cable.
there should be a certain cable for that
"RJ-45 Cross cable" is required for a direct ethernet connetion between two pcsbetween the same type of network devices (PC-to-PC, switch-to-switch, router-to-PC (Note: router and PC are LIKE devices, because both are DTE)) you use Crossover cable.to connect different type of devices (PC-to-switch, PC-to-router ..) you use Straight Through cable.
Same device----> crossover cable Different device->Straight through cable
You should use the USB cable that came with the device you own. But make sure that the USB cable is the right size on both ends, because not every USB cable can fit every device.
