Higher numbers generally mean a better specification since there’s more useful information (the signal) than unwanted data (the noise). For example, when an audio component lists a signal-to-noise ratio of 100 dB, it means that the audio signal level is 100 dB higher than the noise level....

All the files and subfolders that make up the system32 folder are copied to the hard drive during the initial Windows installation, usually to C:\Windows\System32.

DuckDuckGo’s browser has been around on mobile for quite a while. iPhone and iPad users, for instance, can use it to browse privately, blocking trackers and other annoyances, and even set it to annihilate all collected cookies and history when you quit.

Why Your Windows 11 Camera Isn’t Working There are two possible broad reasons: hardware or software. Unlike something within Windows malfunctioning, a webcam is a physical device, so the issue could lie in the device itself or in your computer’s understanding of how to connect to it. Most Windows webcam issues have something to do with software. That is, Windows 11 doesn’t understand the camera is plugged in or the software you’re using (like a browser or video program) doesn’t have the right permissions enabled, effectively blocking access to the camera....
