Computers have evolved greatly over thousands of years, from early counting tools like the abacus to modern electronic devices. The first known computing device was the abacus, created by the Sumerians around 2700 BC to help with counting. Taking the US Census was an early major counting challenge, taking over 7 years to tally by hand in 1790. Herman Hollerith developed a punch card system in 1890 that streamlined the census counting and saved the government $5 million by completing it in just 3 years. This pioneering work led Hollerith to found a company that later became IBM. In 1939, David Packard and Bill Hewlett founded Hewlett-Packard in a Palo Alto garage, helping to advance computing
