plasma
Definition:
Plasma is a technology common to high definition televisions. Considered by many to be the cream of the crop when it comes to high definition televisions because of the accurate colors and deep blacks. Plasma televisions have wide viewing angles but can suffer from a sometimes-exaggerated problem of screen burn-in. Plasma competes with LCD and DLP technologies.
Here's a word you may not know...
DPI
DPI stands for dots per inch and is a common term used to describe the quality of a printer. If you can imagine that a printed character on a page is made up of many tiny dots, the more dots used to create that character, the better the resulting character will look. DPI describes how many of these dots can fit into one inch of a document. The higher the DPI the better the quality of the printed document.
