The idea behind serial numbers is to identify a specific item, much like how a fingerprint identifies a specific person. Instead of some names or numbers that specify a whole range of products, a serial number is intended to provide a unique number to one device at a time. Hardware serial numbers are embedded in the device, while software or virtual serial numbers are sometimes applied to the user who will be using the software....
Most electronics today are built around semiconductors and chips. A solid state drive uses, as its primary storage medium, semiconductors rather than the magnetic platters of a conventional hard drive. SSD Similarities to Traditional Drives Solid state drives and USB flash drives use the same type of non-volatile memory chips that retain information when there is no power. The difference is in the form factor and capacity of the drives....
How RSS Works RSS is a way for website authors to publish notifications of new content on their website. This content may include newscasts, blog posts, weather reports, and podcasts. To publish these notifications, the website author creates a text file with the XML file extension for the RSS feed that contains the title, description, and link for each post on the site. Then, the website author uses this XML file to add an RSS feed to web pages on the site....
ICS Features ICS uses a single computer as the gateway (or host) through which other devices connect to the internet. Computers wired to the gateway computer or connecting to it wirelessly via an ad-hoc wireless network can use ICS. There are several reasons why you might want to set up this type of network: Allows most devices (including non-Windows and older Windows systems) to connect without installing additional client software. Support for all connected clients to use many different protocols, including VPN and internet gaming....
Here’s what you need to know about QNED screens. QNED: The Basics QNED stands for “quantum nano-emitting diode” and is a transmissive display technology that relies on mini-LED backlights. Since LCD pixels are not self-emissive (in other words, they don’t create their own light), most current LCDs use LEDs to light the display from behind. While backlighting technology has improved significantly over the years, LCD TVs can’t offer the bright highlights and deep blacks offered by OLED, which have self-emissive pixels....

During Monday’s opening day of the Worldwide Developers Conference (WWDC) 2021, Apple announced several new additions will be coming to FaceTime when iOS 15 releases in the fall. This is one of the biggest updates that FaceTime has seen, and includes several new features that Craig Federighi, Apple’s senior vice president of software engineering, says should make connecting with friends and family easier than ever. Spatial Audio and Background Noise Suppression Two of the first features coming to FaceTime will provide better audio options for users....
A Look at Voicemail Features The voicemail feature acts similar to an answering machine. However, the main difference is that instead of storing the voice message on the answering machine, it is stored on the service provider’s server, in a space reserved for the user called a mailbox. Voicemail has the same characteristics of email, except that the messages are voices instead of text. Along with recording and playing sounds back, voicemail has these additional features:...
Proprietary vs. Common Batteries Most cameras now require a certain style of battery for a particular camera. Battery styles vary by both manufacturer and camera model. Search for “Nikon battery” or “Canon battery” on the internet, and you’ll find many different shapes of batteries even within that manufacturer’s product line. Some types are for point-and-shoot cameras, while others are for DSLR cameras. Fortunately, most DSLR cameras by one manufacturer use the same style of battery....
Initially spotted by WABetaInfo, the app is working on privacy tools that would put you in more control of who sees your status. With the new customizable feature, you would be able to choose “Everyone,” “Nobody,” “My Contacts,” and now, “My Contacts Except” for your Last Seen. The option to choose who sees what aspects of your WhatsApp profile will go beyond the Last Seen feature and include your Profile Picture and your About, which contains things like your bio....
All iPhone models are relatively similar when it comes to hardware. It’s the software that’s different. Apple releases a user guide that covers all models that can run the latest operating system every time a major new version of iOS comes out. Apple produces other instructional materials, such as product and safety information and QuickStart user guides, for each model. Identify which model you have below, and then download the user guide you need....
How Horn Speakers Differ From Modern Speakers Horn speakers are much larger than their modern counterparts. For example, some vintage Altec Lansing speakers stand four feet high and three feet wide with an imposing multicellular horn perched on top. Because they were designed to run on low-power amplifiers, they are energy-efficient despite their size. Horn speakers come in different designs. For example, Altec offered several different cabinets, including the A5 and the A7....
You may have thought that Apple’s War on Buttons ended when Joni Ive split, but it seems to be lumbering on. According to well-sourced analyst Ming-Chi Kuo, the iPhone 15 may ditch its remaining physical volume and power switches in favor of touch controls with haptic feedback. This could possibly make the iPhone more durable, but it could also make it a lot more annoying. “Its decision to remove the physical home button with a haptic engine was in the right direction, and time has proved it....
A recent update on Oculus’ development blog revealed plans for multi-user accounts and app sharing—two of the biggest features the virtual reality community has been asking for. While the idea of app sharing might not seem that important to the overall future of VR, some believe it will be a vital step in helping to expand the number of people who enjoy VR content. This could then lead to more purchases of Oculus VR devices in the future, especially as the company continues to update and expand the app sharing system....
Why is it so good? Because the biggest iPad not only excels in everything that makes smaller iPads great, it also has a surprising number of other capabilities only possible with the bigger screen. I love my big iPad, and while I sometimes get jealous of the cute 11-incher, the 12.9 is the best all the way. Love At First Sight The first iPad launched in the US back in 2010, and I had a friend buy one and ship it to me in Europe because I couldn’t wait four months to get my hands on it....

The Kindle Scribe is perfect for users who like to take notes and annotate what they read. I’m excited to get my hands on one!...
The new M2 MacBook Air is thin, light, has battery life for hours, and comes in at only a few hundred dollars more than the iPhone. And that’s because it kind of is a big iPhone, which is exactly the computer we’ve been waiting for all these years. “In my opinion, 14- and 16-inch MacBook Pros with M1 Pro and Max were the very first true laptops in the mobile era....
Start saving now because an AirCar, which can drive on roads while also being able to fly, recently completed a 35-minute test flight. A new study found that the cost of a flying car will come in at over $700,000. “Individual, middle-class people may not be able to afford to buy a flying car in the near future or until as early as 2050,” Seongkyu Lee, a professor of aerospace engineering at the University of California, Davis, told Lifewire in an email interview....
Playing video games in VR can cause time to seem compressed, according to new research. The study found that participants who played the virtual reality version of a game first played for an average of 72.6 seconds longer before feeling that five minutes had passed than students who started on a conventional monitor. “Research suggests that perception depends on bodily signals such as our heart rate,” Nick Davidenko, a scientist at the University of Santa Cruz and one of the study’s authors, said in an email interview....
