Question

a device that transmits digital data over analog utility lines and links with an internet service provider is.
a computer
a modem
a utility line
the internet

Explanation:

To solve this, we analyze each option:

• A computer is a general device for processing, not specifically for transmitting digital data over analog lines to an ISP.
• A modem (modulator - demodulator) is designed to convert digital data to analog for transmission over analog utility lines (like phone lines) and connect to an ISP, and vice versa for receiving.
• A utility line is the medium, not the device that transmits data.
• The Internet is a network, not a device for transmission over utility lines to an ISP.
