One of the topics we've covered multiple times at ExtremeTech is the difficulty of continuing to scale semiconductor technology, and the related problem of improving chip performance without ...
Way back in the salad days of digital computing (the 1940s and '50s), computers were made of vacuum tubes -- big, hot, clunky devices that, when you got right down to it, were essentially glorified ...
A vacuum tube, known as the first electronic device, is used to switch, amplify, or commutate electric signals. In the past, vacuum tubes functioned as a main part of a diverse range of electronic ...
Peer inside an antique radio and you’ll find what look like small light bulbs. They’re actually vacuum tubes — the predecessors of the silicon transistor. Vacuum tubes went the way of the dinosaurs in ...
Most people associate vacuum tubes with a time when a single computer took up several rooms and "debugging" meant removing the insects stuck in the valves, but this technology may be in for a ...
Without transistors the modern world would simply not exist. But how do they work, and how do modern, atomic sized versions compare with the originals? The word "transitor" has become almost invisible ...
On this 60 th anniversary of the first issue of EDN, we look back to 1956 when the vacuum tube was at its maturity and transistors were about to begin their domination. The vacuum tube features of ...
