Personal computer usage has evolved from a single stand-alone working machine to one that is connected with other computers, be it through a local network or through the World Wide Web. Because of this, the paradigm of software has also started to change from one that is centred on the stand-alone desktop to the one that is dependent on the internet to store data and applications. With cloud-based computing, your data follows you wherever you are, because it is stored on the cloud. Applications already reside on the cloud too, so again, you no longer need to install anything on your desktop. Cloud-based computing is revolutionizing the way we work with our computers.
