Computers connect to the Internet via a network interface card (NIC) or wireless LAN adapter (WiFi adapter). Historically, computers could also connect to the Internet via a built-in modem for use with telephone lines.
1) You purchase the cable 2) You plug it into the network adapter (network card). If the cable directly connects two computers, you need a crossover cable; if the computers are connected via a switch (this lets you connect more than two computers), you need a straight cable. Make sure to measure how much cable you need, and to purchase some extra length, to let you move the computers around freely.

When you connect to Google Servers on the other side of your country or across the ocean then you need to pay for the cable that those people are providing you on rental bases. You obviously cannot lay your own cable to the servers. You pay for the infrastructure to connect to people around the world.
