In a few museums around the world, there lies the special experience of seeing some of the earliest computers. These room-filling monsters have multiple racks of vacuum tubes that are kept working … ...

The First Transistorized Computer January, 1954: If transistors could replace vacuum tubes in the phone system, then they certainly could replace them in computers too.

It’s best to admit upfront that vacuum tubes can be baffling to some of the younger generation of engineers. Yes, we get how electron flow from cathode to anode can be controlled with a grid,… ...

What does first-generation computer actually mean? Find out inside PCMag's comprehensive tech and computer-related encyclopedia.

ENIAC is the world's first electronic computer. As a stand-alone device, it didn't support networking, although it facilitated a network of humans who used it for years to aid the efforts of World War ...

Researchers have created a semiconductor-free microelectronic system using a gold nanostructure to improve the conductivity of a vacuum-tube system by 1,000 percent. If they are able to make their ...

Techno Page The five phases The history of computer development can be divided into five generations. Each generation is characterised by a major technological development that fundamentally changed ...

Prior to Bell Labs’ first working transistor in 1947, which ushered in the advent of semiconductor technology and the computer age, every long-distance telephone call, radio and television ...

"We're sort of in the vacuum tube days right now with quantum computing -- making these massive machines and trying to figure out how to get better, smaller, more resource-efficient components to ...
