Question!

010000011 Byte = 8 bits

ASCII Code

American Standard Code for Information Interchange

Apple II -> Year 1977My First personal Computer, year

1985!!!

1 Byte = 8 bits

X 2^10 1024 Byte = 1KB

48KB

Question! How many times bigger?

USD 1 = KRW 1150USD 214= KRW 247,000

Electric Power & Tariff

How much of electric power to be consumed if this computer is ‘power on’ for one whole month?

150W x 24Hour x 30Days= 108,000Wh= 108kWh

Korea Nuclear Power Plants (Kori)

One Nuclear Power Plant Capacity 1GW = 1,000MW = 1,000,000kW

Photovoltaic

77

East Sun Power Gen. Co.-24MW, 0.7Mil m2 , US 200Mil.

1 Nuclear Power Plant => 1GW = 1000MW

24MW x 40 approx. 1000MW

Capacity : to be equivalent to 1 Nuclear Power Plant (x 40 times)-> 28 Mil m2 , US 8,000 Mil. (US 8 Bil.)

Power Generation: to be equivalent to 1 Nuclear Power Plant (x 5 times)

(with capacity factor of 20%, tracking device) -> 140 Mil. m2 , US 40 Bil.

** Still we don’t get power during the night, rainy days,…
