Some of them are highly visible, in laptops, tablets, cell phones, and smart watches. But most are invisible, like those in appliances, cars, medical equipment, transportation systems, power grids, and weapons. We never see the myriad computers that quietly collect, share, and sometimes leak vast amounts of personal data about us. Through computers, governments and companies increasingly monitor what we do. Social networks and advertisers know far more about us than we should be comfortable with, using information we freely give them. Criminals have all-too-easy access to our data. Do we truly understand the power of computers in our world? Based on the author's Princeton course Computers in Our Word, this book is intended as a compact but detailed and thorough explanation of how computers and communications systems work, for non-technical readers. It explains how today's computing and communications world operates, from hardware through software to the Internet and the web, also addressing the social, political and legal issues that new technology creates.   Copy/Holding information Location Collection Call No. Status   Hawaii State Library Business, Science & Technology 004 Ke Checked In Add Copy to MyList
