The four required items to connect to the Internet are a computer, a modem, an Internet service provider and a web browser. Devices other than a computer can be used to access the Internet as well.
In order to connect to the Internet you have to have access, which is gained through an Internet service provider. Once access is granted, the computer connects to the Internet through a device called a modem that is often provided by the ISP. When the modem is running, a computer can be connected to the Internet via a web browser. As of 2015, popular browsers include Mozilla Firefox, Google Chrome and Internet Explorer. The Internet can also be accessed with smartphones, tablets and other devices that allow web access.
