Modern computers can access the Internet in many ways. While many computers access the Internet through Wi-Fi, some computers do not have the capabilities. If you have an Ethernet port, you can connect your computer to the Internet using a Ethernet cord and a DSL or cable modem. You can connect Macs and PCs to the Internet in this way, as long as they have Ethernet ports available.
