Children's Literature - Amie Rose Rotruck
While computers are an integral part of the average American life today, a mere fifteen years ago they were considered a luxury or a toy rather than an essential household or business item. Humans have always felt the need to make computation easier, creating things like counting boards and abacuses. The first computers in the late nineteenth and early twentieth centuries used punch cards, which were gradually replaced by vacuum tubes starting in the 1920s. Transistors and microchips not only made computers more reliable, they also made them smaller and cheaper. The popularity of pocket calculators prompted people to think about personal computers. Until then, most people thought that computers were only required for large businesses. People like Bill Gates and Steve Jobs made computers both inexpensive and easy enough for the average consumer. As the computer gained popularity in people's homes and schools, the World Wide Web emerged as a resource for communication and information. The more prevalent computers become, the more uses people find for them. Now, the Ipod and even cell phones have more computing power than Apollo 11 carried! Who knows where computers will take us next? This installment from the "Great Inventions series" is a colorful and informative guide to the history of computers. Reviewer: Amie Rose Rotruck
