How Do Automatic Braking Systems Work? Each car manufacturer has its own automatic braking system technology, but they all rely on some type of sensor input. Some of these systems use lasers, others use radar, and some even use video data. This sensor input is then used to determine if there are any objects present in the path of the vehicle. If an object is detected, the system can then determine if the speed of the vehicle is greater than the speed of the object in front of it....

What OLED TV Is OLED stands for Organic Light Emitting Diode. OLED is an outgrowth of LCD technology that uses organic compounds formed into pixels to create images, without the need for extra backlighting. As a result, OLED technology allows for very thin display screens that are much thinner than traditional LCD and plasma screens. OLED is also referred to as Organic Electro-Luminescence. OLED Versus LCD OLED is similar to LCD in that OLED panels can be laid out in very thin layers, enabling thin TV frame design and energy efficient power consumption....

Uplink vs. Downlink A downlink is a connection made in the opposite direction of an uplink, either from a satellite to the ground or from an outside network into a local network. Internet downloads, for example, travel over a downlink to the downloading device, while internet uploads travel over uplink connections. Uplinks are commonly used in satellite telecommunications to broadcast satellite radio and television. Broadcasters transmit signal feeds from ground stations to the orbiting satellite, a process known as satellite uplink....

HFS+ and HFS (an earlier version of the Hierarchical File System) were created in the days of floppy disks, the primary storage medium for the Mac back when spinning hard drives were an expensive option offered by third parties. Apple flirted with replacing HFS+ over the years. Eventually, APFS, which is already included in iOS, tvOS, and watchOS, became the default file system for Macs running macOS High Sierra and later....

There are multiple reasons to use cloud storage services. Maybe your local hard drives are running low on disk space, in which case you can use the cloud as extra storage. If you want to be able to stream your music collection from anywhere, access your work files at home, easily share vacation videos, etc., you can upload your files online to a cloud storage service. Another reason to use cloud storage is if you want to keep important files secure behind a password and encryption....

What Is ENIAC? ENIAC is an acronym for Electronic Numerical Integrator and Computer. Also known as The Giant Brain, it was the first programmable general-purpose electronic digital computer. In the 1940s, physicist John Mauchly began working on his concept for an electronic calculating machine while teaching at the Moore School of Electrical Engineering at the University of Pennsylvania, which was a center for wartime computing. The U.S. Army needed a faster computer to calculate the trajectory of artillery shells during World War II, and funded his work to develop such a machine....

Which Networks Are GSM? Here’s a quick breakdown of just a few mobile carriers and that use GSM: T-MobileAT&TIndigo WirelessPine CellularTerreStar GSM vs CDMA GSM offers wider international roaming capabilities than other U.S. network technologies and can enable a cell phone to be a “world phone." With GSM, switching SIM cards activates different phones to the same network account. In addition, GSM allows for simultaneous data and voice operation—something CDMA cannot manage....

Paint 3D serves as a replacement for the older Paint program. How to Download Paint 3D Paint 3D is available only on Windows 11 and Windows 10....

What Is NVIDIA Optimus? Optimus is a technology developed by NVIDIA that automatically adjusts graphics based on how you use a device. This optimization better conserves battery power on a laptop computer. It is sometimes referred to as a hybrid graphics system. Optimus automatically transitions between integrated graphics and a discrete GPU based on the applications you use. This allows you to use high-performance graphics during gameplay or when watching an HD movie....

What Is Samsung DeX? Dex extends the Android Multi-Window or split-screen mode, allowing you to multitask easily between apps, tools, and devices. In DeX mode, you can see your full list of apps, access an on-screen keyboard, search for apps and items, and access and edit your phone’s photos and files. You can also reply to text messages and take calls. DeX is not a full-fledged desktop replacement. It’s a companion that is slower and less dynamic than a traditional desktop environment....

The word originally referred to the association between software code and genetic code, where an organism’s DNA, which is physically wet, resembles software instructions. In other words, wetware references the software that belongs to a living organism—the instructions contained within its DNA, similar to how the instructions behind a computer program are called its software or firmware. Computer hardware can be contrasted with a human’s “hardware” like the brain and nervous system, and software can refer to our thoughts or DNA instructions....

Encryption: WhatsApp features end-to-end encryption, which means that your video (and text) chats are all secure from prying eyes, even those at Facebook-owned WhatsApp itself. The app is available on iOS and Android devices and works well on slower networks, making it a good alternative to other encrypted solutions, like the Apple-only FaceTime. Competition: The aforementioned FaceTime allows up to 32 people to chat at once, while Zoom (not encrypted end-to-end) claims up to 1,000 participants at a time....

WhatsApp announced the new disappearing messages additions on Monday. It initially released disappearing messages in 2020, with a later update that made photos and videos immediately vanish after one viewing. Now, though, the instant messenger says it wants to give you more control of how and when your messages poof. Previously, users could only make messages disappear after seven days. You also had to manually turn it on for every single chat....

First up, the app has significantly increased the maximum number of call participants from eight to 32. That’s a whole lot of happy chaos, so the company also added features to make these crowded calls more manageable. For example, you can activate a new mute function just by long-pressing on a participant. This long press is not just for muting, however. It also opens a menu to message the participant, enlarge their feed, or increase their audio....

Overall Findings WhatsApp is designed for mobile devices. In contrast, Skype is mainly a computer-to-computer app that can also call other phones. When the world got more mobile, and when communication shifted from the office or home desk to the pocket, Skype lagged behind. For instance, the apps had limitations, and some platforms were left in the dark for many years, as was BlackBerry. So, Skype is more for the computer user who wants quality, stability, features, and added sophistication to their communication experience....

Learn where to find the Windows Show Desktop shortcut. Where Is the Windows Show Desktop Shortcut? The Show Desktop button is a small rectangle in the far-right bottom corner of the Windows desktop.

VESA (Video Electronics Standards Association) is a fantastic standard, but even the best arms don’t cut it. I have an Ergotron arm, recommended by everyone (including Wirecutter), and its pivots are either scratchy, or too tight, and almost nothing is smooth. When I tilt the display back or forward, I feel like I’m going to bend the screen—and that’s on the loosest setting with lubricant applied. Apple is already in the fancy, expensive stand game, so why not just make an overpriced VESA stand, too?...

Supply of the new consoles will be short for months, the company’s head of investor relations, Mike Spencer, told The New York Times recently. The problem is a lack of chips necessary for manufacturing the units. It’s not helping users that scalpers and bots are snapping up whatever stock they can get for resale. “One of the main reasons there’s an Xbox shortage is because of bot scalpers hoarding stock from November and December,” gaming writer Devin Pickell said in an email interview....
