What year was the transistor invented and by what company? Who invented the first mechanical computer? Where was the first smartphone invented? Who invented the first iPhone? What was the earliest form of writin
GIFs, and digital moviesinto the molecules. The potential density is staggering. All of the world’s digital data could be stored in a coffee mug full of DNA,biological engineersat MIT estimated in a paper earlier this year. The catch is cost: one coauthor later said that DNA synthesis...
While the Altair 8800 was the first personal computer, it was the release of the Apple II a couple of years later that signaled the start of the PC as a sought-after home appliance. The Apple II, from inventors Steve Jobs and Steve Wozniak, proved that there was a demand for computers...
each with a smaller size of transistor than the last in just four years. If you’ve ever heard ofMoore’s Law, you know that shrinking down the circuits to fit more transistors is one of the key ways that chips improve,
The other half of the switch is a bit cunning. At first sight, it looks like it won’t do anything much: it grounds the base of the transistor in both positions, so why is it even there? The answer is a subtle: for an instant while the switch is between positions, that connection...
Isolators (Logic Output, Transistor Photovoltaic Output); Opto Emitters LED SMD; P&P (Filters Ferrite, TVS Diodes); Relays (Power, Signal, Solid State); Sensors (Angle Linear Position Measuring, Current, Humidity, Inertia Accelerometers, Temp Thermistors NTC/PTC); ...
But as transistors start to butt against physical limitations, Intel and other chipmakers have signaled that improvements in transistor-based computing might be approaching a wall. Soon, we will have to find a different way of processing information if we want to continue to reap the benefits of...
Patient samples were collected, and analysis was carried out to discover the reason for the infections. China was the first country to identify the disease, named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by the International Committee on Taxonomy of Viruses (ICTV) (Gorbalenya...
For example the computer could not have been conceived without the prior 'invention' of the transistor, itself born of the idea behind the valve whose own generation could only have been brought about after the discovery of the properties of semiconductors, preceded by that of the electron and ...
the cost." Paniccia says progress has been rapid over recent years with the demonstration of high-performance silicon Raman lasers and high-speed modulators and photodetectors. "In 2003, the fastest silicon modulator was 20 MHz and earlier this year [2007] we announced a 40-Gbit s–1 model...
