Accessing all important data at the office, across the enterprise or the world at any time is possible and easy with servers. Computers, laptops or tablets are not the only devices that communicate over a network. Printers, scanners or cameras can also be plugged into a network and exchange data. With appropriate permissions, provided within a network, each user can access content released for him on a server or provide his own content for other users. Data storage media or special hard disk housings with cloud feature allows, e.g. to access music tracks and videos with smart phones from any location. Thus, personal data are available at any time, anywhere.
