Ethernet connection to Desktop

[andrew.machado2009]

My Desktop does not have an Ethernet Card. I don't want to install LAN CARD. The Broadband Modem has an Ethernet Port.
How can I connect to the internet without installing Ethernet Card.
Is there method to use the USB Port in my Desktop for the internet connection.

Which OS are you using?

I *think* you might be able to use a USB, but you should have an ethernet card .. unless the PC is really really really old
