To Access The Internet Dial Home Computer

How does the dial-up connection work?

The working principle is simple. The user connects its modem to the ISP’s modem through telephone line by dialing up the ISPs number. It is exactly like dialing up your phone to get it connected with the phone of the callee just replace the phones with the modems. Once this connection is established a link between the modem of user and the modem of ISP is developed. When the user types a URL in its browser the ‘request’ packets travel through its telephone lines and reaches at the ISP’s modem which them routes it to the website host through the internet. The host will send the requested packets back to the ISP and the ISP routes these packets to the user’s modem and the website page opens up on the screen of the user’s computer.
