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 requirement
DCE devices in the sense hub,bridge,switch,modem etc are dce devices we use
i hope it is useful to you........
Data circuit-terminating equipment (DCE) is a device that connects to the leased line provided by the telco. The term circuit-terminating refers to the fact that a leased line is sometimes called a data circuit, or simply a circuit, and the CSU/DSU sits at the end of the circuit. The DCE also provides clocking to the data terminal equipment (DTE). The DTE is a device that needs to send data over a circuit. Routers act as DTEs because they need to send IP packets, encapsulated in data link frames, over WAN links.

a serial interface on a router is basically used for WAN communications. we generally connect to other routers through internet using serial interface. In a lab scenario we generally emulate WAN connections by connecting the serial interfaces of the routers using a cable called DCE/DTE cable.

ATM switches, core switches and frame relay switches are WAN devices that can be found in the cloud.

An LAN card is a must if you wish to connect to a LAN but it is not required for WAN
A WAN or wide area network connects devices over several platforms. It can be wireless or wired or both.
It is referred to as a point-to-point WAN link, aka a leased line.
LAN: Limited geographical area usually within the same building. WAN: Larger global Network with no physical boundaries.
