This electromechanical machine, used in the 1890 U.S. census, was the first automated data processing system.
As the country grew, each census required greater effort than the last. That problem led to the invention of the punched card – and the birth of an industry.
Many people worry that software updates slow their computer down.
It can feel like your computer slows down after it updates, here’s why.
Older people are often labelled technophobic, but since lockdown the digital divide is closing as more and more use technology to connect with others.
Once a pioneer of the information age, now stereotyped as the browser of choice for people who are less than web-savvy, the curtain will finally come down on Internet Explorer next year.
The Morpheus secure processor works like a puzzle that keeps changing before hackers have a chance to solve it.

Most computer security focuses on software, but computer processors are vulnerable to hackers, too. An experimental secure processor changes its underlying structure before hackers can figure it out.
Most of the world’s electronics are not recycled, posing health and environmental risks.
Technical advances are reducing the volume of e-waste generated in the US as lighter, more compact products enter the market. But those goods can be harder to reuse and recycle.
Neural networks try to simulate the brain by processing data through layers of artificial neurons.

Neural networks today do everything from cameras to translations. A professor of computer science provides a basic explanation of how neural networks work.
Brainlike computer chips promise powerful computers that use little energy.

Artificial brains are far in the future, but computer chips that work like brains could keep computers advancing when today’s silicon transistor chips reach their limit.
Six hours of streaming video may be the equivalent of burning one litre of petrol.
With online learning, children are staring at computer screens for more hours each day.

With online learning and social distancing, kids are spending more time staring at screens and less time outdoors. That can put them at higher risk of myopia and serious eye problems in the future.

Electronic waste is accumulating and is a resource to be exploited. Microfluidic devices allow the development of recycling, including the recycling of rare earths – a precious resource.
Windows 7 users are being urged to buy a new laptop but they could be just as well off not bothering.
When algorithms make decisions with real-world consequences, they need to be fair.
A machine learning expert predicts a new balance between human and machine intelligence is on the horizon. For that to be good news, researchers need to figure out how to design algorithms that are fair.
Many Kenyan students have had limited access to computers.
Integrating technology into schools involves understanding the dynamic relationship between technology, how it’s used in the classroom and the content of the curriculum.
Coding can enhance children’s creativity and their understanding of mathematics.
Coding is beneficial to children, irrespective of their career path later on in life.
Will quantum computers ever reliably best classical computers?
Google claims quantum supremacy – IBM says not so fast. One researcher explains why he doesn’t see quantum computers outpacing classical computers any time soon … and maybe not ever.

The first computer, named the ABC, was built at Iowa State University. But for a long time, few had heard of it.
Researchers have developed implants small enough to fit inside brain cells.
An algorithm is just following rules designed either directly or indirectly by a human.
Algorithms are only human (well, designed by humans) but we need to trust they’ll do what they’re supposed to do. And that means we need a better way to test them.
