👉 Understring, also known as a "cable," is a type of cable that is used in conjunction with other devices to transmit data over a network. It is typically made up of several strands of wire, each one being insulated and connected end-to-end. The purpose of an understring is to provide a reliable connection between the different components of a network, such as routers, switches, and servers, so that they can communicate with each other seamlessly.
