Backing up

It's very important to backup your work for example I save all my work on my pen stick and a hard drive at home.
But you could also use things like the cloud and any other website like the cloud like dropbox or one drive.
I have personally used Dropbox as you get a free 2 GB space to save your files on which is a lot of space when you are only using it for documents etc.

Facebook Settings

These are my Facebook settings which i'm going to share in my blog

You can change these settings at anytime I use these personally as I think its secure and that no one can just search my stuff on Facebook.
Some people may decide to have their Facebook open so that anyone can see it at any given time.

internet explorer security settings

With internet explorer you are able to set settings, with each of the 4 modes displayed on the screen you will be able to set your own custom settings or select the few options they have with the bar
From Low to Medium to High.

Each settings are better for different types of users - people who are new to using the internet should use high settings until they get use to what they are doing then they can lower the settings to have more freedom on the web.
