Course Introduction:1. How much electricity does a desktop computer use per day? The total power consumption of a computer running for a day is about 12 kilowatt hours, which includes the power consumption of the host, monitor and other external devices. If you play for twelve hours a day, the power consumption is about 4 kilowatt hours. 2. How much electricity does a freezer use per day? Refrigerator doors are marked with energy consumption ratings. This level is the most energy-saving power consumption index for refrigerators at room temperature. However, it is not necessarily accurate. Its daily power consumption depends on the environment of the refrigerator, the frequency of opening the refrigerator door and the set temperature. The environment is hot, or the door is opened frequently, which will cause the compressor to start frequently and increase power consumption. I think the variable frequency version might save a little bit, it would be less than one degree per day. If it is a mechanical version, the energy consumption would be about 1.2 degrees at level 2.

Course Introduction:1. How much did the world’s first computer weigh? The world's first computer weighed 30 tons. The world's first electronic computer was named "ENIAC" and was successfully developed by Eckert and others at the University of Pennsylvania in 1946. On February 14, 1996, the first computer was born. It consists of 17,468 electron tubes, 60,000 resistors, 10,000 capacitors and 6,000 switches. It weighs 30 tons, covers an area of 160 square meters, consumes 174 kilowatts of power, and costs US$450,000. This computer can only perform 5,000 addition operations per second, which is only equivalent to an Electronic Numerical Integration Computer (ENIAC, "ENIAC"). The first electronic computer contained 1800
