    1. Normally, a person blinks  about 20 times a minute, but a computer user blinks only 7 times a minute! To prevent eye strain, follow the 20-20-20 rule:

      • Every 20 minutes, look at something 20 feet away from your computer or TV screen for 20 seconds. Why 20 seconds? It takes your eyes that long to relax!

       

    2. ENIAC was one of the earliest computers made, and was made public in1946 in Pennsylvania. It was called a "Giant Brain" by the press. It contained 17,500 vacuum tubes, linked by 500,000 connections. It filled a 50-foot long basement room and weighed 30 tons (60,000 pounds). Today, a single microchip, no bigger than a fingernail, can do more than those 30 tons of hardware. Its total cost was about $500,000 which is approximately $6,300,000 today.
    3. Computer circuitry can be destroyed by static electricity. It is so mild for humans that we don't even feel it.
    4. Computer memory is measured in bytes. A byte is the unit computers use to represent a character such as a letter, number or symbol (like @ or #). It's the smallest unit of memory in most computers. A petabyte (PB) is a larger unit of memory. Today, personal computers do not have that much memory...yet! See how much a petabyte can hold!

      • 1 PB = 500 billion pages of standard typed text
      • 1 PB = 20 million 4 drawer filing cabinets filled with text
      • 1 PB = 13.3 years of HD-TV video
      • 1 PB = Over 4,000 digital pictures per day for your entire life
