A PC or laptop that’s running slowly can be incredibly frustrating, particularly if you’re relying on it to stay productive.

Compared to DVD, let alone Blu-ray, VHS tapes are poor quality.

Ransomware is nasty malware which installs itself on your computer, encrypts your documents and other important files. It will then demand a ransom – usually a Bitcoin payment – which you have to pay to get the ‘key’ to decrypt your files again.

That’s why it’s crucial in this day and age to take preventative measures to protect your important files from this type of attack....

The Oculus Quest 2, like most standalone VR headsets, are very social in design – and we’re not just talking about multiplayer games. The wire-free nature of the headset allows you to bring it to gatherings and introduce friends and family to the wonders of virtual reality.
