Windows operating system comes with both Kernel and User modes, but not everyone knows the difference between both. In fact, most users have no idea these modes exist, but yet they’ve used them before ...

However, SeL4 can be used, in theory, as a foundation for Linux and other Unix related operating systems. For example, it was briefly considered for use in Richard M. Stallman's still-born Gnu Hurd ...

A team had been able to prove with mathematical rigour that an operating-system kernel – the code at the heart of any computer or microprocessor – was 100 per cent bug-free and therefore immune to ...

Ultimately, every problem in the constantly evolving IT software stack becomes a database problem, which is why there are 418 different databases and datastores in the DB Engines rankings and there ...

A team of Yale researchers has unveiled CertiKOS, the world’s first operating system that runs on multi-core processors and shields against cyber attacks, a milestone that the scientists say could ...

If you’ve ever wondered if all of Apple’s operating systems—macOS, iOS, iPadOS, watchOS, and tvOS—are really based on the same code, today’s updates should show just how true that is. We suspect this ...

When a CPU generates a trap or an exception, and the operating system kernel is not able to catch that particular trap, it gives out an annoying Blue Screen with the ...

Google is working on a new operating system — and it has nothing to do with Android. A page has surfaced on the code-sharing website GitHub about the new OS, called — for now, at least — Fuchsia. It's ...

Australian researchers have demonstrated a way to prove core software for mission-critical systems is safe. The researchers on Thursday said they can prove mathematically that code they have developed ...

Last week, a group of Googlers did something strange: They quietly revealed a new operating system that theoretically competes with Google’s own Android OS. Dubbed Fuchsia, the open-source ...

Virtualization technology, whereby multiple operating systems can be run on shared hardware, is extremely well understood if somewhat inefficient in its use of resources. Just a few decades ago, ...
