The address for a webpage (called a URL) can give good information about what might be found on that site. The parts of the address give clues.
http://computer.institution.domain/directory/filename.xxx
http:// most addresses begin with this - which just means you are going to see a web page.
https:// this is a secure site - it would be safe to give them credit card information
computer: most addresses begin with www, but not all
institution: this can be the full name or an abbreviation. The person or group who created the web page often works for this organization
domain: the six most common "top" level domains are:
directory: an address can have several levels here or none at all
filename.xxx: the address can end with different "extensions", such as pdf, htm, or html
Local government or state websites will use a two letter state code - such as ak for Alaska. Other countries will use a two letter country code.
What is the country code for where you were born?
