FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -The more surface, the more pressure, and the more pressure the screen was resisting, the thicker the glass had to be. CRT TVs were also bulky because the electron guns that fire electrons at the inside of the screen need a certain angle of attack to work properly.

Detailed explanation-2: -CRT monitors are big, bulky and heavy. They are not a good choice if you’re working with limited desk space, or need to move the monitor around (for some odd reason) between computers. An LCD on the other hand is small, compact and lightweight.

Detailed explanation-3: -LCDs are more compact, more energy-efficient, and cost less to make. They can also be made with larger screen sizes than CRT monitors. They’re vastly lighter; a 21-inch CRT display can weigh between 50 and 60 pounds, and some weigh nearly 100 pounds.

Detailed explanation-4: -Although it is almost like a TV, its resolution is much higher than a TV. Older monitors were built by using a fluorescent screen and Cathode Ray Tube (CRT), which made them heavy and large in size and thus causing them to cover more space on the desk.
