VirtualBox is one of the best virtualization softwares available for operating systems. Basically, it allows you to run multiple operating systems in the "mother system", in various configurations and with various settings. This allows you to test the behavior of programs in different environments - check software compatibility with different systems, the detection of conflicts between different applications or for the study of their interaction with the operating system. Virtual machine can be installed "at will", thus it doesn't slow the performance of the primary operating system.
The program allows you to add to the system virtual USB devices and optical drives which are present in the core system. It is possible to perform snapshots of the current state of the virtual machine and use the machines in full screen mode (useful for all people who are making tutorials). Installation is simple and it literally takes just a few clicks to add a new virtual machine and make it ready to run
VirtualBox Open Source Edition was released as free software on the GNU General Public License which means you can distribute it and also use it for commercial purposes, meaning you don't have to worry about selling apps you make later. Currently, VirtualBox runs on both 32 and 64-bit Windows and Linux. It supports many types of virtual systems, including 4.0/2000/XP/2003/Vista/7 Windows NT, DOS / Windows 3.x, Linux (2.4 and 2.6), OpenBSD and Solaris.

In modern times, having several computers and using multiple devices connected to the Internet is nothing special. Dropbox provides the ability to store files in the cloud and easily access them from any Internet device.
Client installation is available on all popular platforms, so you can easily synchronize files with all sorts of systems you use. Clear and functional web interface allows you to access data from any Internet-connected computer, without installing any programs.
Dropbox runs in the background by synchronizing all the changes that you make in the folder "My Dropbox" with the cloud. This process does not slow down the system in a noticeable way. Another interesting solution used by its authors is instantly uploading files when another Dropbox user have in his account the same file. Unfortunately, the "My Dropbox" folder is the only folder which can be synchronized.
Dropbox keeps a limited history of changes made with your files and information about files that you removed. It allows you to recover an important file which was deleted or overwritten.
Dropbox provides us a free 2GB of data in the cloud. It may seem that this is not much, but if you use it to synchronize the documents you are currently working with, configuration files and other key data to which you want to have remote access, then 2GB is enough. There is also possibility to get more cloud space, but of course you have to pay for it.
Dropbox is a great solution for those unfamiliar with the subject of data synchronization. Its easy to use even for beginners.
