What is the role of DCE in networking?

The role of DCE, or Data Communication Equipment, in networking is crucial as it refers to devices that facilitate the transmission and reception of data over a communication medium. DCE typically includes devices such as modems, routers, and switches that are essential for establishing communication links between different networks or network segments.

DCE is responsible for providing physical and sometimes logical control of the data flow in a network. This ties into how DCE interfaces with Data Terminal Equipment (DTE), which refers to devices like computers or terminals that generate or use the data. In many communications scenarios, DCE devices act as intermediaries, ensuring that signals are properly formatted, timed, and can travel across the network effectively. This distinction is vital for understanding how data is transmitted from one point to another in a networked environment.
