What Are Autofocus Points? Autofocus points are what the camera uses to focus on a subject. You’ll probably first notice them when you press the shutter halfway. Many cameras will emit a beep, and some of the AF points will light up—often in red or green—in the viewfinder or on the display screen. When your DSLR is left on automatic AF selection, you’ll know where the camera is focusing by which AF points light up....

During installation, there are a few details you can set up immediately :...

If this is the case, then the WD Blue SN500 NVMe SSD makes for a compelling and affordable upgrade to rejuvenate your PC. Design: Bland but functional Aesthetic appeal is of minimal, potentially nonexistent importance when selecting internal computer components, but it’s still worth a mention....
Type of Protection/Security: In a Class All Its Own Webroot is not quite like any antivirus application you’ve ever seen before. Traditional antivirus works by storing known virus definitions on your hard drive and using those to recognize threats to your system. Some antivirus may even monitor the way your computer system behaves to find anomalies that might indicate your system has been infected with malware. Webroot, does both in what it calls a Deep Scan....
The compact portable generator market, ranging from 1600 watts to 2300 watts, is full of impressive competition. There seems to be a subsegment for every consumer, from entry-level to high-end, and everything in between. Based upon its price tag and spec sheet, the WEN 56200i seems to falls into the former category. In order to see if it was a diamond in the rough or a thorough bargain-basement option, we put it through 18 hours of testing at varying power loads....

What Is a Mesh Network Router? Mesh networking relies on a set of mesh routers linked together. This is not new technology; mesh networks have been used by the military since the 1980s, for example. But the first mesh routers became commonly available for home and consumer buyers with models like the Eero and Orbi starting around 2016. A mesh router is not a single device like a traditional router; there can be two, three, or even more routers in a mesh system....
The first platform games were developed in the early 1980s making it one of the earliest video game genres to exist, but the term platform game or platformer wasn’t used until a number of years later to describe the games. Many game historians and fans consider the 1980 release of Space Panic to be the first true platform game while others consider then 1981 release of Nintendo’s Donkey Kong to be the first....
Typically, the device powers on when a user presses the button and powers off when they press it again. A hard power button is mechanical—you can feel a click when pressed and usually see a difference in depth when the switch is on versus when it’s not. A soft power button, which is much more common, is electrical and appears the same when the device is on and off. Some older devices have a power switch that accomplishes the same thing as a hard power button....
How Is a Roomba Taught to Vacuum? In most basic models, the Roomba uses a random pattern to clean the floor. It will change direction when it senses an obstacle using infrared sensors, but otherwise, it’s not following a specific order. More complex models will learn a floor plan over time and use that to offer more options, but there’s no artificial intelligence in the device. However, it doesn’t just clean the same place over and over again....
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:...
