Whether you're just looking for information about your system or trying to help a friend with their PC, it's good to be able to find out basic information about your computer. While there are plenty of ways to dig up this info on your machine, a variety of websites make it easy to find out what system you're using.

Here are three websites you can visit quickly anytime to get information about your machine, or have a friend visit when you're helping them over the phone.

If you're not sure what browser (or what version of the browser) you're using, a quick visit to WhatIsMyBrowser will let you know. What's more, the site will also show you if the browser is up-to-date, along with the status of JavaScript, Flash, and other plug-ins and browser settings. If you want to share this info with a friend, the site includes a unique URL that can be sent to whoever is providing you tech support.

Not sure what your operating system (OS) is? WhatMyOS will let you know without thrills, and also provides methods on how to check your exact OS version.

Finally, if you're not sure of your external IP address, you can use IP Chicken to quickly view your public IP address. Websites can gather information about where you're located using this address.
