What Are WAV & WAVE Files? A file with the .WAV or .WAVE file extension is a waveform audio file. This is a standard audio format seen mainly on Windows computers. The file is usually uncompressed but compression is supported. Uncompressed WAV files are larger than other popular audio formats, like MP3, so they’re typically not used as the preferred audio format when sharing music files online or buying music, but instead for things like audio editing software, operating system functions, and video games....
Understanding Mobile Carriers In the U.S., there are three major national carriers for mobile phone service: Verizon, T-Mobile, and AT&T. (A fourth, Sprint, was acquired by T-Mobile in 2020.) In the industry, each of these companies is classified as a mobile network operator (MNO). Each MNO must have a radio spectrum license from the Federal Communications Commission (FCC), as well as own and maintain their own network infrastructure to provide the cellular service, which includes the use of transmitters and cellphone towers....
Asymmetric DSL Asymmetric types of DSL connections are faster and provide more network bandwidth for downloading from the internet service provider to the subscriber’s computer than for uploading in the other direction. By reducing the amount of bandwidth available upstream, service providers can offer more bandwidth downstream, which reflects the typical subscriber’s needs. Forms of asymmetric DSL include: ADSL (asymmetrical digital subscriber line) has a downstream rate of up to 8 Mbps and an upstream rate of 384 Kbps....
Buying Blank Discs Before you can record a TV program or transfer camcorder tapes to DVD, you need to purchase a blank disc. Blank DVDs can be found in most consumer electronics and computer stores, and can also be purchased online. You can buy one disc, a few discs, a box or spindle of 10, 20, 30, or more. Some come with paper sleeves or jewel box cases, but those packaged in spindles require separate sleeves or jewel boxes....
What Is a TFLOP and What Is It Good For? The performance of a computer isn’t easily quantifiable. A PC that’s great at one task might be just average at another, while a modern desktop might be more capable than a supercomputer from a decade ago, depending on the tasks you set it. Clock speeds, core counts, and even instructions per second aren’t always directly comparable either. Floating-point operations per second, or FLOPS, and more recently TFLOPS are a measurement that can cross generations and even different components, to give a firmer measurement of what a computer is can do....
How to See and Install Widgets on the iPad You can customize the notification center to show and add widgets, as well as choose to access the notification center while the iPad is locked, so you can see your widget without typing in your passcode. Here’s how to see, customize, and add widgets to your iPad. How to Know Which Apps Include Widgets Unfortunately, the only way to tell if an app has a widget you can add to the Today view is to download it and then check the list on the Edit screen....
External SATA is an industry standard for controlling the various hardware used to connect external storage devices. It competes with some Firewire and USB standards to provide faster data transfer speeds between hardware devices. How Does eSATA Compare With USB and FireWire? Both USB and FireWire interfaces are high-speed serial interfaces between a computer system and external peripherals. USB is more general and used for a wider range of peripherals such as keyboards, mice, scanners, and printers....
The Benefit of HDMI ARC HDMI ARC transfers audio from a TV to a home theater receiver with the same HDMI connection that transfers video from the home theater receiver to the TV. With HDMI ARC, you can hear TV audio through a home theater audio system instead of the TV’s speakers without also connecting analog or digital optical audio cables between the TV and home theater system. How an Audio Return Channel Works If you receive TV signals over an antenna, audio from those signals goes directly to your TV....
What Is Echo? (Definition and Details) The primary Echo device is two speakers and some computer hardware wrapped in a sleek black cylinder. It comes equipped with Wi-Fi, which it uses to connect to the internet, and it can connect to your phone through Bluetooth. It also pairs with a variety of accessories to automate your life, shop, watch TV, and play music. Echo Frames are smartglasses that deliver content and notifications through two inconspicuous speakers in the arms of the gadget....
What Is Galaxy Fit? Both the Galaxy Fit and Galaxy Fit E are designed to automatically track activities, including walking, running, rowing, biking, and elliptical exercises. Users can track up to 90 additional types of activities when they connect the Galaxy Fit to the Samsung Health app. However, those activities will need to be started manually from the app. Both Samsung wearables also have heart rate monitors, but only the Samsung Fit tracks your heart rate 24/7....
Primarily owing to its much higher cost, WiMAX is not a replacement for Wi-Fi or wireless hotspot technologies. However, it can be cheaper to implement WiMAX instead of standard wired hardware as with DSL. What is WiMAX? WiMAX equipment comes in two basic forms: base stations, installed by service providers to deploy the technology in a coverage area; and receivers, installed in clients. WiMAX is developed by an industry consortium overseen by a group called the WiMAX Forum, which certifies WiMAX equipment to ensure that it meets technical specifications....

It can often be hard to tell which issue a USB device is having when trying to connect to your Windows 10 device, so it can be a good idea to work through potential solutions until it begins working properly....
Check for Service Interruptions If you’re trying to watch a video through iTunes, you can check Apple’s system status page to make sure services are all available and running at peak level. If you’re trying to watch video through a non-Apple app, you’ll need to check the app developer’s website to ensure their product is running the way it should. These sites vary from app to app, but more popular apps like YouTube or Netflix generally make it easy to find if they’re having issues with their service....
Email Signature Placement Email recipients generally expect to see your email signature right below the end of your text. That makes it the best choice for new messages. In replies, however, a condensed version or none at all is a good option; after all, the recipient already knows who you are. This is particularly important in long threads with multiple participants, in which repeated signatures can get unwieldy and annoying....
Albums is an iPhone and iPad app that takes your music seriously. At first glance, you’ll see a nice grid of album covers, and you can tap one to play it and see the track listing. But then you notice the info panel, hidden behind an innocent-looking ⓘ (information) button. Tap this, and you’ll fall into a rabbit hole of music. It’s like being back at the record store, only without the twitchy DJs and the condescending staff....
The Echo Frames are pretty much just an Alexa speaker, embedded into a pair of glasses. But that’s enough for many people, with the bonus that the glasses don’t end up bulky and dorky. Also, smart audio assistants can be a huge boon to people with limited vision. “For blind or low-vision people, audio AR can significantly extend their ability to interact with the world,” sound artist and augmented reality writer Halsey Burgund told Lifewire via email....
The current Instagram policy forbids children under the age of 13 from using the service. The company reportedly is working on a version of the social media service that would be ad-free and feature parental controls. While details haven’t been announced, some observers are skeptical. “An app solely for kids with no credible way to assure that the profiles on there are actually underage can be very toxic and unhealthy, as many children can be exploited and manipulated into doing things that are not meant for them,” Brandon Walsh, who runs the parenting blog DadsAgree, said in an email interview....
