By capturing the signals from satellites, GPS receivers are able to use the mathematical principle of trilateration to pinpoint geographic locations. With the addition of computing power and memory such as road maps, points of interest, and topographic information, GPS receivers are able to convert location, speed, and time information into a useful display format. The Invention and Evolution of GPS GPS was originally created by the United States Department of Defense (DoD) as a military application....

How Packet Switching Works Packet switching breaks data into several parts that are packaged in specially formatted units called packets. These are typically routed from the source to the destination using network switches and routers. Then the data is reassembled at the destination. Each packet contains address information that identifies the sending computer and intended recipient. Using these addresses, network switches and routers determine how best to transfer the packet between hops on the path to its destination....

It’s not unusual for smartphone operating systems to follow in the footsteps of their competitors. That seems to be the case with Android 12, as Google is doubling down on privacy features similar to those Apple already has released for iOS. While the move to include more features like Android 12’s Privacy Dashboard is good for users and delivers some great additions that iPhone users already get to enjoy, it ultimately fails to deliver the same level of privacy protection....

I don’t think we’re one hundred percent there yet....

What Is an ASF File? A file with the ASF file extension is an Advanced Systems Format file developed by Microsoft that’s commonly used for streaming audio and video data. An ASF file can contain metadata like a title, author data, rating, and description. The structure of the audio or video data is understood by an ASF file, but it doesn’t specify the encoding method. WMA (audio) and WMV (video) are the two most common kinds of data that’s stored in the ASF container, so ASF files are most often seen with one of those file extensions....

AT&T announced Monday that it would be instituting several new changes to its Unlimited Elite phone plan, currently the company’s highest-cost mobile plan.

That’s the idea behind Continuity Camera, which automatically grabs a wireless feed from your iPhone’s camera when it’s sitting near your Mac, and you make FaceTime, Zoom, or other video calls. The result is incredible. In fact, it’s so good, it’s worth keeping an old iPhone around just to use as a webcam. “Apple’s Mac lineup […] is often criticized because of its webcam, which has considerably poor quality despite Apple having far better quality camera modules in their other devices, especially iPhones,” Rajesh Namase, technology writer and co-founder of TechRT, told Lifewire via email....
