Computers are pretty amazing devices (you should know... you couldn't use Experimonkey without one!), and Computer Science is the study of data and how we can use computers to operate on it. Hopefully these Computer Science facts compute with you.
The Apollo Guidance Computer (ACG), which helped U.S. astronauts reach the Moon in 1969, had 64 kB of memory and a CPU speed of 43 kHz. An iPhone X, in comparison, has 3 GB of memory (about 47,000x more), and 2 CPUs running at 2.39 GHz (each about 56,000x faster).
Rather than using computer chips and their microscopic transistors like we have today, the earliest computers used what are known as vacuum tubes to store information. Thousands of these tubes, resembling small light bulbs, were required to build computers—and extremely weak ones by today's standards. The ENIAC, a computer built in 1945 for use by the U.S. military, had a mass of 27,200 kg and measured 2.4 m × 0.9 m × 30 m, occupying 167 m2 of space.
