Answer:
The old cathode Ray tube technology was replaced by the less bulkier and more modern liquid crystal display and LED technology.
Explanation:
The old cathode ray tube uses the principle of electrical discharge in gas. Electrons moving through the gas, and deflected by magnetic fields, strike the screen, producing images and a small amount of X-rays. The tube required more space, and consumed more electricity, and was very bulky. The modern technologies are more compact and consume less power, and can been designed to be sleek and less bulky.
The answer is Laser Printer. It is a non impact printer that creates characters and images with dots by using a drum and toner. The main advantages of laser printers are speed, precision and economy. A laser can move very quickly, and because the laser beam has an unvarying diameter, it can draw more precisely, without spilling any excess ink.
