What Is Compression? Compression reduces the size of any file on a computer, including image files. However, for photographs, compression is not always a good thing because compression can affect image quality. Different photography file formats on DSLR cameras and computers apply different levels of compression. When an image is compressed—in a camera or a computer—less information is in the file, and the finer details of color, contrast, and sharpness are reduced....

Overall Findings TVs are the standard because they’re simple to set up. TVs work with nearly every device you can imagine. The costs are reasonable. And, you don’t need to be a home theater expert to get satisfying results. Projectors can be great, and they do have their applications. However, you’ll pay more for 4K, need to design your room around screen placement, and put more effort into designing and configuring your home theater....

At a recent auction, a combination sale including a jeweled physical crown coupled with a digital non-fungible token (NFT) version sold for more than $1 million. Meanwhile, custom-made digitally wearable Dolce & Gabbana jackets attracted more than $300,000 bids in the digital currency Ethereum. It’s part of the growing interest in NFTs, a record of a digital item confirmed by a blockchain platform. “Virtual clothing is not real and can not be worn,” Kevin Mirabile, a professor of finance and business economics and an expert on alternative investments at Fordham University, told Lifewire in an email interview....

Working from home could be worse, I thought to myself. This setup was not on a spaceship, but instead came courtesy of the newly updated Virtual Desktop app ($19.99) for the Oculus Quest 2. Read on for more details, but here’s the takeaway: Just go out and buy it if you have an Oculus. This isn’t Virtual Desktop’s first rodeo on the Oculus. In 2019, the app arrived on the Quest allowing wireless PC streaming, but the feature was later removed....

In the old days, the discontinuation of a battery size might have made a camera unusable. Today, it’s usually down to software of some sort. Often, we don’t notice. We’ve already convinced ourselves to move onto the newer, “better” model. But this gadget rot is a serious problem that renders perfectly good devices useless. “E-waste is a serious environmental concern,” digital consultant and gadget fan Julian Goldie told Lifewire via email....

What Is a Hybrid or Convertible Laptop? In essence, a hybrid or convertible laptop is any type of portable that can essentially function as either a laptop or a tablet computer.

What Is a MIDI File? A file with the .MID or .MIDI file extension (pronounced as “mid-ee”) is a Musical Instrument Digital Interface file. Unlike regular audio files like MP3s or WAVs, these don’t contain actual audio data and are therefore much smaller in size. They instead explain what notes are played, when they’re played, and how long or loud each note should be. Files in this format are basically instructions that explain how the sound should be produced once attached to a playback device or loaded into a particular software program that knows how to interpret the data....

There are several kinds of Wi-Fi adapters, both internal and external. The one you choose depends on the type of computer you have, available ports, and how much you’re willing to spend. What Does a Wi-Fi Adapter Do? A Wi-Fi adapter allows you to connect your desktop or laptop computer to your wireless router so that you can access your home network and the internet. Without a Wi-Fi adapter, you would need to run an ethernet cable from the router to your computer and plug it into your computer’s ethernet port....

dasHost.exe is used to connect wireless and wired devices to the computer, such as a printer or mouse. You’ll likely run into it only when browsing through Task Manager; it’s listed along with other running services. It’s also visible in the System32 folder. Usually, this file is 100 percent clean of threats and causes no problems. However, if you see multiple dasHost.exe files running or one or more of them are hogging an excessive portion of the CPU or memory, you need to investigate further to see if it’s a virus....

Google Lens Is a Visual Search Engine At a basic level, Google Lens is a visual search engine. It analyzes the visual data of an image to perform tasks based on the contents of the image. For example, if you take a picture of a landmark and then tap the Google Lens shutter, Google Lens recognizes the landmark and pulls up relevant information from the internet. Depending on the landmark, this information can include a description, reviews, and contact information if it’s a business....

Command-Line Interfaces Ruled Past Computer Interaction To really appreciate GUI design, it helps to know what preceded it. Before GUI was commonly used, computer screens only displayed plain text and were controlled by a keyboard. Interactions with the computer were typed into a command line. So, instead of dragging and dropping a file to move it, users typed the command name, the name of the file to be moved, and the destination directory....

Offline backup is usually an added cost and you’ll only be charged for it if you utilize the feature. Why Should I Use Offline Backup? Some initial backups made to an online backup service can take days, or even weeks, to complete, depending on lots of things like the number of files you’re backing up, the speed of your internet connection, and the size of the files. Considering the added cost, offline backup is usually only a good idea if you know that backing up everything you have via the internet will take longer than you’re willing to wait....

To make a long story kind of short, Snapchat is an app that truly changed how people interact with friends compared to other popular social networks like Facebook and Twitter. Not everyone gets it—particularly older adults—but Snapchat is all the rage among even the youngest smartphone users, including teens and young adults. Users can chat with their friends by sending them photos, short videos up to 10 seconds long. Think of it as texting through pictures or videos; text chats and video calls are two other features are a key part of the app....

But if we use the term to describe a site like Facebook, and also a site like Digg, plus a site like Wikipedia, and even a site like I Can Has Cheezburger, then it starts to get more confusing. Just what exactly is social media, anyway? The term is so vague that it can basically be used to describe almost any website on the internet today. Or can it? Some people have more of a restricted view of social media, often equating it to mean the same as social networking (a....
