T

TFT: Thin Film Transistor. TFT or 'active' displays have become the standard display technology for LCD screens and offer a wider viewing angle, brighter images and faster redraw times than older passive matrix displays.  

Travel weight: The total weight of a notebook package for computing on the road, including the notebook, transformer, and external drive (each about two-thirds of a pound), a full-size battery (if the built-in battery is underpowered), and possibly an adapter module for connecting accessories to a small notebook. Unless you see the words travel weight, assume the weight you're quoted is "system weight," and add 1 or 2 pounds to get the actual travel weight. Add another 2 to 3 pounds for an expansion slice.
