We’ve seen our share of homebrew computers over the years. Usually, these bare-bone systems use a small, early 80s-era microprocessor such as the Z80 or 6502. These little 8-bit machines are awesome, ...

Imagine a world where people could only talk to their next-door neighbor, and messages must be passed house to house to reach far destinations. Until now, this has been the situation for the bits of ...

How would we handle metastability in our 4-bit computer if we were to implement it as a microcontroller chip, a single-board computer, or a cabinet-based system? Now, after laying all of this ...

What we are going to do is design a simple 4-bit computer at the primitive logic gate and flip-flop level and then implement it in the technology of our choice I’ve often wondered what would happen if ...

A quantum computer could provide an enormous improvement in the processing speed of existing computers. However, as yet they only exist in the laboratory in the form of small prototypes with a ...

CPUs that process 64 bits as a single unit, compared to 8, 16 or 32. Today's desktop and laptop computers are mostly 64-bit machines; however, there are countless 32-bit, 16-bit and 8-bit ...

A new version of the pocket-sized BBC micro:bit computer is coming to schools worldwide, packed with new features designed to keep young students up-to-date with the latest hot trends in technology.

I've got a shelf full of computer history books, many of which I love and have reread several times. But I wanted to write one that focused on the first real computer I grew up with, the one that ...

A team of computer engineers from quantum computer maker Quantinuum, working with computer scientists from Microsoft, has found a way to greatly reduce errors when running experiments on a quantum ...

Quantum mechanics allows for some very strange things, like the teleportation of information and computers that can break even the toughest codes. Recently, scientists at the Swiss Federal Institute ...

If there was one downside to 8-bit computers like the Commodore 64, it’s that they weren’t exactly portable. Even ignoring their physical size, the power requirements would likely have required a ...
