E Ink
E Ink is the name used to describe the screen on an e-reader. It’s different to a normal computer screen, because it isn’t backlit. That means it’s easier to read in daylight. Also, E Ink screens use almost no power at all, giving you massive battery life.
EPG
Electronic Programme Guide – this is the on-screen programme list for what’s on your TV, usually found by clicking the ‘TV Guide’ or ‘Guide’ button on your remote control.
EP Mode
Extended Play mode featured on a Panasonic DVD-RAM recorder. Can offer up to 12 hours of record time when used with a 4.7 gigabyte blank disc.
Ethernet
A PC interface used to connect computers and peripherals in a Local Area Network (LAN). Huge amounts of data can be transmitted quickly over Ethernet cables — from 10Mbps to 1Gbps.
Exposure
Exposure is the amount of light which falls upon the sensor of a digital camera. Shutter speed and aperture are adjusted to achieve optimal exposure of a scene. Most digital cameras offer a variety of exposure modes — from fully-automatic to semi-automatic to full manual control. Scene modes have factory optimized settings for different subjects and scenes.
EX Surround
Films with Dolby Digital EX Surround have a third rear channel for more realistic effects: you get a better spread of sound behind you and this adds more realism. To take advantage of this ‘back surround channel’ you need a compatible processor and an extra speaker which is placed between the two at the back. DTS also has its version of EX called DTS-ES.
