In a serial connection, what does DCE stand for?

The term DCE stands for Data Communications Equipment. In the context of serial connections, DCE refers to the equipment that facilitates communication between various devices within a network. This includes modems, routers, or other devices capable of transmitting and receiving data over communication lines. The DCE is responsible for providing the timing signal on the line and often connects to the DTE (Data Terminal Equipment), such as a computer or terminal.

Understanding DCE is crucial for network configuration and troubleshooting, as it typically influences how devices are connected and how data is transmitted across the network. Recognizing this distinction helps network professionals understand the roles that different equipment plays in facilitating data communication, ensuring efficient network design and operation.
