In the computer, all data are represented as binary digits (bits), and eight binary digits make up one byte. For example, the upper case letter A is 0101001. Numbers however can take several forms.

Binary is a number system that only uses two digits, \(0\) and \(1\). It was invented by German mathematician Gottfried Wilhelm Leibniz. Binary code is used widely in computer programming, so it is ...

Consider a simple black-and-white image. If 0 is black (or on) and 1 is white (or off), then a simple black-and-white picture can be created using binary. In a low-resolution image, the pixels are ...

A new DNA computer calculates square roots of perfect squares up to 900. Like quantum computers, DNA computers are an exciting frontier of post-silicon computing. Where previous examples were up to 4 ...

Memo to the developers of superfast quantum computers: give up on the familiar 1s-and-0s binary system used in conventional computers. By switching to a novel five-state system, you will find it ...
