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.

We worked our way up to logic gate implementations for half adders and full adders, as illustrated below. In closing, I asked you to start thinking about how we could use these functions to add two ...

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 ...

It’s hard to believe today, but in the 1940s, the earliest computer technicians actually worked at the bit level. If a computer made a mistake and the technician determined it wasn’t from a burned-out ...

The formulation of the binary number system essentially laid the groundwork for digital circuitry, computers, and the field of computer science, as we know it in today’s technologically-advanced world ...

Beginners often have difficulty reading the value of –2’s complement number; here’s a simple technique that may help. In my previous column, I introduced the SANX-I Microcomputer, whose goal is to ...

One of the things I love to do is teach people about computers, especially how we can use them to represent and manipulate different types of numbers (I really need to get out more). For the purposes ...
