What Is an XML File? An XML file is an Extensible Markup Language file. They are plain text files that don’t do anything in and of themselves except describe the transportation, structure, and storage of data. An RSS feed is one common example of an XML-based file. Some XML files are instead Cinelerra Video Project files used with the Cinelerra video editing program. The file holds project-related settings like a list of past edits made to the project as well as paths to where the media files are located....

What Is Dolphin Browser? The Dolphin web browser is an entirely free app that adapts to how you use it, so its features are always relevant and convenient. It’s one of the oldest web browsers for smartphones, and thanks to features like tabbed browsing, it feels more like the same experience you get on a desktop browser than most alternatives. It works just like other web browsers so you can set it as your default option for when you click a link in a message, providing you with extra options on how to interact with web content....

Fibre Channel vs. Fiber Optic Cables Fibre Channel technology supports both fiber and copper cabling, but copper limits Fibre Channel to a maximum recommended reach of 100 feet, whereas more expensive fiber optic cables reach up to 6 miles. The technology was specifically named Fibre Channel rather than Fiber Channel to distinguish it as supporting both fiber and copper cabling. Fibre Channel Speed and Performance The original version of Fibre Channel operated at a maximum data rate of 1 Gbps....

File transfer encryption helps prevent someone, who may be listening or gathering information during a data transfer, from being able to read and understand what’s being transferred. This kind of encryption is accomplished by scrambling the data into a non-human readable format, and then decrypting it back to a readable form once it has reached its destination. When Is File Transfer Encryption Used? File transfer encryption is usually used only when data is moving from one computer to another computer or server over the internet, though it can also be seen in things much less long-distance, like wireless payment systems....

Defragmentation, then, is the process of un-fragmenting or piecing together, those fragmented files so they sit closer, physically, on the drive or other media, potentially speeding up the drive’s ability to access the file. What Are File Fragments? Fragments, like you just read, are simply pieces of files that aren’t placed next to each other on the drive. That might be kind of strange to think about, and nothing you would ever notice, but it’s true....

Apple iOS uses a multi-touch interface in which simple gestures operate compatible devices, such as swiping your finger across the screen to move to the next page or pinching your fingers to zoom out. There are millions of iOS apps available for download in the Apple App Store, the most popular app store of any mobile device. Much has changed since the first release of iOS with the iPhone in 2007....

Here’s what you need to know about QLED screens. What Are Quantum Dots? The more general term for QLEDs is “Quantum dot displays,” which have two types: photo-emissive (or photoluminescent) and electro-emissive (or electroluminescent). Consumer-level QLED TVs are all photo-emissive displays that exist in direct competition with OLED sets, which produce the same resolutions but work differently. The main difference between QLED displays and their competitors is the former’s use of “quantum dots....

Some files that end in this extension may instead be annotation files used with the Amaya web editing program. How to Open an ANNOT File ANNOT files are best opened with the free Adobe Digital Editions program. This is the software that lets you create the notes, bookmarks, etc., but also, of course, to see them visually within the book. However, since the format is the text-based XML, any text editor can be used to view the information, too....

A rumor appeared this week that Sony will shut down the online storefronts for three of its old consoles—the PlayStation 3, Vita, and PlayStation Portable—this summer. Once that happens, owners won’t be able to buy content digitally for each system, which has the potential to take dozens of old video games out of circulation. Sony has yet to comment on the issue officially, but this was inevitable. It’s impressive that Sony held out this long—the PSP has been discontinued for over seven years—before pulling the plug....

How: WhatsApp only supports iPhones running iOS 9 or later and Android smartphones running version 4.0.3 or later. Why Do You Care: If you’re still relying on an older phone, you’ll need to upgrade it or its OS to match the current supported specs to continue using WhatsApp. WhatsApp’s support page says phones running older systems have been able to use the popular chat app until that date, implying the app will no longer work on these older mobile operating systems....

Fortunately, you can still find the updated document on your hard drive. Here’s where to look.

To find that folder’s common location: Files you have opened in Mail will be in sub-folders. You can arrange them by creation date, for example, to find the most recently opened file fast: ~/Library/Containers/com....

A recently discovered AirDrop flaw lets strangers see your phone number and email address just by opening an iOS or macOS sharing pane within the Wi-Fi range of other people. It’s one of a range of privacy vulnerabilities Mac and iOS users should know about. “Our iOS devices are connected to countless social media apps, third-party messaging platforms, and networking sites that allow people to share all sorts of content with each other,” Hank Schless, a security expert at cybersecurity firm Lookout, said in an email interview....

Pen and paper are our most fundamental way of writing and drawing, and the one that is probably the most comfortable. And yet, outside of graphic design and other specialist uses, we rarely use it to interact with our desktop computers. The new Surface Pen might not change that, but it does bring one crazy innovation to the pen-on-glass game: haptic feedback that vibrates the pen to mimic the feel of writing and drawing on paper....

The 49-inch Odyssey Neo G9 costs a jarring $2,499.99 when it goes on pre-order this week. I love small electronics. The iPad mini still holds a special place in my heart. But as I age, my failing eyes are crying for bigger and better displays. Go Big or Go Home I recently transitioned from a MacBook Pro to the 24-inch M1 iMac, and the larger display has made a massive difference in my productivity....

The model I’m most looking forward to is the Kindle Paperwhite Signature Edition, which has an auto-adjusting light sensor, 32 GB of storage, and wireless charging for the first time. This model comes with a larger 6.8-inch E-Ink display that’s brighter and has an adjustable color temperature, USB-C charging, a faster processor, and weeks more in battery life. Big Screen Benefits It’s safe to say that I’m obsessed with e-readers....

Tesla CEO Elon Musk recently unveiled the automaker’s first humanoid robot. The electric vehicle company will develop a humanoid robot prototype dubbed the “Tesla Bot.” It’s one of a growing number of robots under development that attempt to match the look and abilities of people. “Human-like robots will be useful because they can more easily work alongside or in place of the humans who must perform the many ‘dull, dirty, and dangerous’ tasks that we depend on humans to solve, but are unpleasant for humans to perform,” Brendan Englot, a professor mechanical engineering at Stevens Institute of Technology, told Lifewire in an email interview....

Why Are There Only 13 DNS Servers? There are a couple of reasons the internet Domain Name System uses exactly 13 DNS servers at the root of its hierarchy. The number 13 is a compromise between network reliability and performance. It’s also based on a constraint of Internet Protocol version 4 (IPv4), which most networks use. While only 13 designated DNS root server names exist for IPv4, each root server name represents not a single computer but a server cluster consisting of many computers....

It took him a few seconds to realize that he’d been scammed. The tip-off came with the multiple pop-up ads that burst onto his phone screen and the inability to escape the website he’d been taken to. A reboot, a quick virus scan, and a few choice words later, my very tech-savvy husband sat, stunned, wondering how he had fallen so easily for a text phishing scam more commonly known as smishing....

Microsoft really wants its Edge web browser to be popular, to the point that it’s actively making it a challenge to set other browsers as the default in Windows 11. The Verge explains that, while changing defaults is still possible, if you miss the “Always use this app” toggle when starting up a new browser, you’ll have to start digging into menus. The process now involves changing individual file or link type defaults one-by-one for the browser you want to use....

Microsoft is expected to reveal Windows 11 on June 24, but a leaked copy of an early build has already been making the rounds. The leaked version doesn’t include every change coming to the operating system when Windows 11 drops, but it does give a good look at some of the big UI changes coming. These changes include a centered start menu more akin to macOS’ dock, as well as rounded corners on many of the File Explorer windows....
