A network-attached storage (NAS) device stores files in a form which is accessible over a network. They typically consist of a specially designed computer without display or keyboard, containing one or more hard drives and running an operating system designed specifically for the management and administration of those files. In the home, NAS devices are often used to store files which are intended to be shared between a number of computers, mobile devices or media playback devices, such as connected TVs and music systems.
A wireless system that allows suitably equipped devices to transfer data over very short distances – usually of just a few centimetres – or by coming into physical contact with each other. NFC can be used for contactless payments or function as an electronic key. NFC-enabled Android smartphones can use Android Beam to transfer files. This uses an initial NFC connection to set up a Bluetooth file transfer.
Created by nVidia, G-Sync is a technology that enables compatible monitors to synchronise with the variable frame rates of certain nVidia graphics cards rather than the graphics cards synchronising to a standard monitor refresh rate (typically 60Hz). This allows the graphics cards to run at their maximum speed without creating a ‘tearing’ effect on screen.
