Summary Businesses use the Internet for e-commerce,
communications, collaboration, and training.
Internetworking standards ensure that all devices connecting to the Internet use the same set of rules.
All Internet connections are made through an Internet Service Provider (ISP).
Multiple ISPs join together at an Internet Exchange Point (IXP) to gain access to each other’s networks.
ISPs must provide a reliable and scalable network.
ISP organizations are composed of many teams offering a range of support services.
