Modems, switches, hubs, bridges, servers, and printers are also nodes, as are other devices that connect over Wi-Fi or Ethernet. For example, a network connecting three computers and one printer, along with two more wireless devices, has six total nodes. Nodes within a computer network must have some form of identification, like an IP address or MAC address, for other network devices to recognize them. A node without this information, or one that’s offline, no longer functions as a node....

Examples of Mashups Back when the Nintendo Wii came out, it was difficult to find it in stores. A web mashup might have helped consumers by taking data from various retailers like EB Games and GameStop, along with websites like eBay, and combining their information with Google Maps, so it could all be presented in an easy-to-use interface. Trendsmap is one example of a popular mashup service. It combined Twitter’s trending topics with data from another Twitter trend site and displayed it on a map....

What Is an Emulator? IBM conceived the concept of computer emulation as a way to run programs designed for older devices on newer models. The method IBM used relied on a combination of software and hardware dedicated to emulation. Rather than designing new applications for its new computers, built-in backward compatibility gave developers greater flexibility. Today, the term emulator is commonly used in the context of video games. The video game emulator became popular during the 1990s because it allowed people to play older console games on modern desktop computers....

If you’re considering purchasing an inkjet printer, take a look at how these printers work and are used. What Is an Inkjet Printer? An inkjet printer is a peripheral that attaches wirelessly or by cable to a computer. In the home, it receives documents or images from the computer and prints on bond paper or high-quality photo paper.

Flexographic printing uses flexible photopolymer printing plates wrapped around rotating cylinders on a web press. The inked plates have a slightly raised image and rotate at high speeds to transfer the image to the substrate. Flexography inks can print on many types of absorbent and nonabsorbent materials. Flexography is well-suited to print continuous patterns, such as for gift wrap and wallpaper. Unlike the individual sheets of paper used in offset printing, the rolls of material used in flexography allow large orders to run with few interruptions to reload the substrate....

How Does Waze Work? There are plenty of GPS-driven apps and software to choose from, including options that may have come pre-installed in your car’s dashboard interface or on your mobile device like Google Maps and MapQuest. Most do a respectable job when it comes to step-by-step navigation. Some account for congestion and other factors that could affect your overall drive time. Waze handles things a bit differently. It relies on the power of the people to steer you down the right roads....

European legislators have proposed new laws that could put strict limits on AI. The legislation is moving forward even though a recent study finds the regulations could cost the EU economy around $36 billion over the next five years. Some observers argue that such measures are needed in the US, as well. “As our society transitions towards a digitally enabled environment, an unregulated AI could lead to misuse, potentially undermining our rights to privacy and data protection,” Joseph Nwankpa, a professor of information systems at Miami University in Ohio, told Lifewire in an email interview....

FOMO For a service like Facebook, the Fear of Missing Out makes sense. Its business depends on engagement....

Earlier this year, New York Governor Andrew Cuomo made headlines when he announced a bill that would force internet service providers (ISPs) to sell internet service to New Yorkers in certain areas for $15 a month. Following the announcement, ISPs hit back hard, lobbying against the bill and even filing a lawsuit because of it. Now, a judge has put the bill on hiatus, citing the possibility of “irreparable harm” to telecom companies if it were to go into action....

In May, Facebook announced plans to bring end-to-end encryption to its Messenger app by 2022. While many praise the use of this encryption method in online messaging services, some recently have expressed concerns that adding it to Facebook Messenger could open the door for abusers to contact younger users without any form of moderation. Others say encryption is worth the risk, and some suggest Facebook could offer a back door instance that could be used to monitor specific messaging threads....

While there are a ton of augmentative and alternative communication (AAC) devices on the market, experts believe Look to Speak has a place among them thanks to its flexibility and accessibility. “There are other eye gaze systems, but they require special hardware, so this is pretty groundbreaking,” Allison Hilger, an assistant professor at the University of Colorado Boulder, and speech-language pathologist, told Lifewire over the phone. How It Works The app uses facial recognition technology already built into smartphones....
