For a monthly fee that can be for a limited amount of connection time, or unlimited usage, the subscriber gets access to the Internet. There are hundreds of ISP companies located throughout the country. However, all types of Internet access options are not available in every area. All you need to buy is a modem. For a monthly fee, most Internet service providers supply their subscribers with an access number, user name, password, and email account.
Many companies also provide Web space to their subscribers.
The Internet access software is usually provided by the ISP for free. Dial-up access is ideal for laptop computer users because they can access their account from any telephone line. Unlike the modem in your PC that dials into your ISP, DSL provides a constant, dedicated connection to the Internet. There are no busy signals or waiting time for connection. Your data and image uploads and downloads are even faster than with cable modems.
