Computer Information Technology

When "metadata" became breaking news, appearing in stories about surveillance by the National Security Agency, many members of the public encountered this once-obscure term from information science for the first time. Should people be reassured that the NSA was "only" collecting metadata about phone calls - information about the caller, the recipient, the time, the duration, the location - and not recordings of the conversations themselves? Or does phone call metadata reveal more than it seems?

Information is power, and the time is now for digital liberation. Access Rules mounts a strong and hopeful argument for how informational tools at present in the hands of a few could instead become empowering machines for everyone. By forcing data-hoarding companies to open access to their data, we can reinvigorate both our economy and our society. Authors Viktor Mayer-Schönberger and Thomas Ramge contend that if we disrupt monopoly power and create a level playing field, digital innovations can emerge to benefit us all.

Our DANTES study guides are different! The Computing and Information Technology DANTES/DSST Test Study Guide teaches you everything that you need to know to pass the DSST test. This is a replacement for the Introduction to Computing Test, which was renamed as Computing and Information Technology.

This book eliminates intimidation with clear, jargon-free guidance and practical steps to keep you and your loved ones safe online. It’s never too late to take control of your digital security.

John Seely Brown and Paul Duguid show us how to look beyond mere information to the social context that creates and gives meaning to it. Arguing elegantly for the important role that human sociability plays, even - perhaps especially - in the digital world, The Social Life of Information gives us an optimistic look beyond the simplicities of information and individuals.

America is at war, but most of its citizens don't know it. Covert information warfare is being waged by world powers, rogue states - such as Russia, China, Iran, and North Korea - and even terrorist groups like ISIS. This conflict has been designed to defeat and ultimately destroy the United States. This new type of warfare is part of the Information Age that has come to dominate our lives.

"Big Data" is on the covers of Science, Nature, The Economist, and Wired magazines, on the front pages of the Wall Street Journal and The New York Times. But despite the media hyperbole, as Christine Borgman points out in this examination of data and scholarly research, having the right data is usually better than having more data; little data can be just as valuable as big data. Borgman, an often-cited authority on scholarly communication, argues that data have no value or meaning in isolation; they exist within a knowledge infrastructure.

Each of us has an ever-growing collection of personal digital data: documents, photographs, PowerPoint presentations, videos, music, emails, and texts sent and received. To access any of this, we have to find it. The ease (or difficulty) of finding something depends on how we organize our digital stuff.

Threats from synthetic media, such as deepfakes, present a growing challenge for all users of modern technology and communications, including National Security Systems (NSS), the Department of Defense (DoD), the Defense Industrial Base (DIB), and national critical infrastructure owners and operators.

What do you know about hacking a computer system? If you are like most of us, you can't even get into your own computer if you've forgotten the password. The good news is that hacking is actually a lot easier than you think, and anyone can learn how to do it. As long as you are willing to do the work and to work through the steps patiently, you will also be able to hack the systems that you want to.
