The definition of a modem is a tool that sends and receives a signal to create a network and Internet connections. An example of a modem is a tool that lets a computer connect to the Internet. : a device that changes the form of electric signals so that information can be sent through telephone lines from one computer to another computer. : a device that converts signals produced by one type of device (as a computer) to a form compatible with another (as a telephone).
