URL

URL stands for Uniform Resource Locator. Also known as a "web address", it is a string of text that is used to specify the location of a resource on the Internet. If the URL is directing you a public location on the Web, it will contain the "www." locator within the address.

for example:

www.col.org

USB

USB is short for Universal Serial Bus. They are the most common connection openings, or ports, on computers today. Computer headphones, USB flash drives, wireless connectors, keyboards and many other devices can be connected by plugging into the USB port.

There are two versions of the USB port: USB 1.1 and USB 2.0 but there is no physical difference between the two and devices will fit in either one. USB 2.0 allows a faster transfer of data.
