Why do you need a modem to connect to the internet?

A modem is required to connect to the internet because it serves as the bridge between your device and the internet service provider's network. The modem converts the digital data from your device into analog signals that can be transmitted over telephone lines, cable lines, or fiber optic cables to connect to the internet. It also receives incoming data from the internet and converts it back into digital data that your device can understand. Essentially, the modem is necessary to establish a connection and communicate with the internet.

A modem is not always necessary to connect to the internet. If you have a wired connection, a modem is not needed. However, if you are connecting to the internet wirelessly, a modem is required to convert the analog signals from your phone line into digital signals that your computer can understand.
