A great technological and scientific innovation of the last half of the twentieth century, the computer has revolutionized how we organize information, how we communicate with each other, and even the way we think about the human mind. Computers have eased the drudgery of such tasks as calculating sums and clerical work, making them both more bearable and more efficient, whatever the occasional frustration they carry with them. The computer has become a standard fixture in our culture, a necessity for many aspects of business, recreation, and everyday life. In this book, Eric G. Swedin and David L. Ferro offer an accessible short history of this dynamic technology, covering its central themes from ancient times to the present day.
