There are two main types of camcorder image sensors: charged coupled device (CCD) and complementary metal oxide semiconductor (CMOS). Both types of image sensor technology contain hundreds of thousands or even millions of pixels. Think of a pixel as a tiny bucket that captures light and turns it into an electrical signal. How CMOS and CCD Sensors Differ In a CCD image sensor, pixels capture light and move it toward the edge of the chip, where it’s converted into a digital signal....

Intel believes it will “provide the ultimate gaming experience”—until the next ultimate experience comes along, anyway—and will allow even more speed for overclocking enthusiasts. However, we’ll have to wait until the i9-12900KS has been publicly released to put all of this to the test. Key features and capabilities for the i9-12900KS, as listed by Intel, start with a maximum speed of up to 5.5 GHz (when using Intel’s Thermal Velocity Boost feature)....

What Is an HGT File? A file with the HGT file extension is a Shuttle Radar Topography Mission (SRTM) Data file. These files contain digital elevation models, which are 3D pictures of a surface, usually a planet, obtained during the Shuttle Radar Topography Mission (SRTM) by NASA and the National Geospatial-Intelligence Agency (NGA). Used here, “HGT” is just an abbreviation for “height.” The file is normally named with the longitude and latitude that the image pertains to, within one degree....

OpenAI has released a new version of Codex, an artificial intelligence (AI) system that translates written language into code. Codex won’t quite allow you to program without any experience, but there are a growing number of ways that people can do just that. “Many products allow users to add images, create layouts for websites and mobile applications, and define data to pull from without ever writing code,” Fahim ul Haq, the CEO of Educative, an education platform for software developers, told Lifewire in an email interview....

Online software tools that help students write essays using AI have become so effective that some teachers worry the new technology is replacing creativity during homework assignments. Students are increasingly turning to these programs that can write entire paragraphs or essays with just a few prompts, often leaving teachers none the wiser. “As far as I can tell, it is currently not that easy to detect AI writing,” Vincent Conitzer, a professor of computer science at Carnegie Mellon University, told Lifewire in an email interview....

Purpose of Network Protocols Without protocols, devices would lack the ability to understand the electronic signals they send to each other over network connections. Network protocols serve these basic functions: Address data to the correct recipients.Physically transmit data from source to destination, with security protection if needed.Receive messages and send responses appropriately. Consider a comparison between network protocols with how a postal service handles physical paper mail. Just as the postal service manages letters from many sources and destinations, network protocols keep data flowing along many paths continuously....

The Evolution of DVDs The DVD format supports a natural video resolution of 720 x 480 (480i). When you put a disc into a DVD player, the player reads this resolution. Hence, DVD is classified as a standard resolution format. This worked well when the DVD format debuted in 1997, but DVD player manufacturers soon decided to improve DVD image quality. They implemented additional processing to the DVD signal after it was read off the disc but before it reached the TV....

A new report published by the National Institute of Standards and Technology (NIST) shows the results of 65 new facial recognition algorithms created after the start of the COVID-19 pandemic, as well as 87 algorithms submitted pre-pandemic. The report revealed that software developers are getting better at developing algorithms that recognize masked faces, even getting as accurate as regular facial recognition algorithms. “While a few pre-pandemic algorithms still remain within the most accurate on masked photos, some developers have submitted algorithms after the pandemic showing significantly improved accuracy and are now among the most accurate in our test,” the report reads....

Wi-Fi standards are certified by the Institute of Electrical and Electronics Engineers. Each Wi-Fi standard is rated according to its maximum theoretical network bandwidth. However, the performance of Wi-Fi networks doesn’t match these theoretical maximums. The actual speed of a Wi-Fi wireless network connection depends on several factors. Theoretical vs. Actual Network Speeds Current Wi-Fi networks support a variety of standards. An 802.11b network typically operates no faster than about 50 percent of its theoretical peak, around 5....
