To access the Internet, you do not typically connect your computer directly to the backbone. Instead, you connect it to an Internet Service Provider (ISP) that in turn connects to the backbone. An ISP is a point of access to the Internet. An ISP typically provides a connection to the Internet and an e-mail account. Some ISPs offer proprietary services that are available only to subscribers. These services might include content channels with articles on health, hobbies, investing, and sports; activities specially designed for kids and teens; antispam and security software; a variety of voice and text messaging services; and free (and virusfree) software. ISP customers arrange for service, in this case for Internet access, for which they pay a monthly fee. In addition to a monthly fee, an ISP might also charge an installation fee. The ISP that you select should provide service in the places that you typically use your computer. If your work takes you on the road a lot, you’ll want to consider a national ISP that provides local access numbers in the cities that you visit.
