But Why Only Base 2? Computers don't understand words or numbers the way humans do. Modern software allows the end user to ignore this, but at the lowest levels of your computer, everything is represented by a binary electrical signal that registers in one of two states: on or off. To...
Why Computers use Binary The ignition switch of an automobile isdiscrete—it has definite states—but there are usually more than two states (off, running, start, acc...) A button on a hand calculator is a binary device. It is either on or off. Ordinarily it is "off." When you push...

importantly, general purpose quantum computers could significantly weaken, even kill, current cryptography systems used to hide and secure data so that only certain people can view it. in other words, a quantum computer of sufficient power will instantly render today’s security systems obsolete and...
Owasso Public Schools in Oklahoma has used Gaggle since 2016 to monitor students outside of class. For years, Tim Reiland, the parent of two teenagers, had no idea the district was using Gaggle. He found out only after asking if his daughter could bring her personal laptop to scho...
In this chapter: When describing how computers work to someone new to PCs, it’s often easiest to haul out the old notion that a program is a very large collection of instructions that are performed from beginning to end. Our notion of a program can include certain eccentricities, like loop...
unknown variables of a discrete variable are predicted based on known value of other variables. The response variable is categorical, meaning it can assume only a limited number of values. With binary logistic regression, a response variable has only two values such as 0 or 1. In multiple logi...
But they’re only intelligible to humans. Computers draw GUIs, but they’re not intelligible to the computer. + Languages as interfaces Above, I described a programming language as a “medium of exchange” between humans and computers. In that way, languages fit...
I am way behind in my work, but I just cannot resist trying to answer your question on why a "byte" has eight bits. The answer is that some do, and some don't. But that takes explaining, as follows: If computers worked entirely in binary (and some did a long time ago), and di...
