What is a URL?

URL stands for uniform resource locator, or the address on the World Wide Web where one can find documents and resources

A URL can be divided into parts

The first part identifies the protocol (ftp for executable files, and http for web pages)

The second part identifies the resource name and gives the IP address where the resource can be located

find a website you like, click on the star in the location bar. To return to the website later, click on the star and a list of your favorites are displayed.

Troubleshooting Internet Connection Problems

The obvious: unplug modem and router, wait, and plug back in. This solves a majority of connectivity issues.

If you recently installed software, make sure installation was successful.

Run a ping command – the command sends a message to the web server. Howtogeek.com has tutorials for running this command.

Use the Down For Everyone Or Just For Me tool to determine if the problem is with the website.

If all else fails, call internet service provider.
