“Cloud” is the abbreviated term for cloud computing, whereby applications and data are no longer stored on local computers and servers, but on remote servers. For example, you can upload all of your music, text files, videos and contacts to a cloud and access them no matter where you are – on your laptop, work computer or smartphone (although you do need to have an internet connection!). In other words, the data are stored centrally and not specifically on a single device. You can also allow other people access to the data.
