Do computers obey the law of conservation of energy?

Writing data to a memory card doesn't store energy in it. When you write data into a flash drive or EEPROM, all you're doing is pushing electrons onto a piece of semiconductor, in patterns of 0's and 1's. read more

Conservation of energy applies only to isolated systems. A ball rolling across a rough floor will not obey the law of conservation of energy because it is not isolated from the floor. The floor is, in fact, doing work on the ball through friction. read more
