What Does Direct Cable Connection (DCC) Mean?
In Microsoft Windows, Direct Cable Connection (DCC) is a feature which allows computers to be connected with the help of infrared or with the serial or parallel ports of computers. In other words, Direct Cable Connection is a link between the input/output ports of two computers, established with the help of an interfacing device. For computers where an Ethernet adapter is absent, this is an advantageous way to transfer files and access resources.
With the advent of features like Ethernet, Bluetooth and Wi-Fi in the current generation of computers, the support for Direct Cable Connection has mostly ceased with newer versions of Microsoft Windows.
