If your PC does not have Ethernet or WiFi interfaces, then it could have serial port. Buy a 56k modem, connect it to a phone line, subscribe for dial-up service - and you will have Internet. Welcome to 1990's, CompuServe, AOL et al
If you turn couple of years back - Google offered Internet service thru the sewer lines. On April 1st, though...
Ummm....well, there are wired network types other than Ethernet (token ring, FDDI, Local Talk, all pretty much obsolete), and other wireless network types other than Wi-Fi (Bluetooth, Zigbee, Li-Fi, various cellular).
