Basics of Information Technology for Non-Specialists: What Happens Inside Machines

Computers surround us everywhere, including household appliances, cars, medical equipment, transportation systems, power grids, and weapons. However, most of them remain invisible, collecting and sometimes merging our personal data. This makes us vulnerable to governments, companies, and criminals who may use the information for their own purposes. The second edition of the popular book "Basics of Information Technology for Non-Specialists: What Happens Inside Machines" by Brian Kernighan examines the principles of how computer hardware, software, and networks work. New sections are devoted to programming in Python, big data, machine learning, and much more.
