Step-by-step explanation:
The correct answer to the question 'The first [ Select] connected users to the ¨net using phone wires. Computers made a phone call through a device called a [ Select ] which [ Select ]' is 'Modems, Modem, Transmitted signals'. Early users connected to internet services via standard phone lines and modems, long before the development of broadband connections and wireless technology. A modem modulates and demodulates signals to transmit information over telephone lines to and from the internet. While routers are also critical components in network infrastructure, they are used to direct data packets within and between networks, but not for the initial connection via phone lines.
