There are many other differences between the two, which should help you decide which cable and converters you may need to use. Overall Findings Video Graphics Array (VGA) was the standard video cable for computers when it was first released in 1987 and are easily recognizable by their blue 15-pin connectors. At that time, the supported resolution was 640x480, but eventually expanded in stages up to Ultra Extended Graphics Array (UXGA) in 2007....

A History of Video Game Emulators Video game emulators became popular in the 1990s with the rise of personal computers and the web, which allowed aspiring developers to work together and create software capable of emulating their favorite game consoles like the Atari 2600 and the Nintendo Entertainment System. The goal of emulation is generally to match the experience of using the original hardware, but many game emulators include extra features like options to integrate cheats, take screenshots, and create save states....

The VIVO VP01W is a low profile universal projector mount that’s designed for standard ceiling heights. It has a decent range of tilt and swivel motion, and can be rotated, but there is no height adjustment. Since it’s a universal mount, it can be used with most projectors that weigh under 30 pounds. We recently installed one of these mounts in a home theater setting to get some first-hand experience with how easy they are to install and adjust, how reliable they are, and how they hold up under real-world conditions....

High-performance EVs boast blisteringly quick acceleration, hit impressive top speeds, and exhibit excellent handling as well. Gasoline-powered vehicles offer stiff competition and benefit from over 100 years of accumulated research and development, but this is one race that might be tighter than you expect. How Do EVs Stack Up to Gasoline-Powered Vehicles? Electric and gas-powered vehicles come in lower-performance budget models, high-performance luxury models, and everything in between. There are many more gas vehicles on the road, which means there are more low-performance and high-performance gas models than electric vehicles, but electric vehicles have an advantage at both ends of the spectrum....

The American Automobile Association (AAA) suggests using contactless payments or gloves and a disinfectant at the pumps. “There are ways motorists can minimize touching surfaces when filling-up: using gloves/plastic bags or contactless payment are two options to consider," said AAA spokesperson Jeanette Casselano in an email. “Regardless, when touching the pump (and screen), we suggest using gloves or plastic bags as a barrier to touching the surface, using disinfecting wipes/hand sanitizer after filling up, wipe down the card as well....

What Are Expansion Slots Used For? The expansion card is plugged directly into the expansion port so that the motherboard has direct access to the hardware. However, since all computers have a limited number of expansion slots, it’s important to open your computer and check what’s available before you buy one. Some older systems require the use of a riser board to add additional expansion cards; however, modern computers not only usually have enough expansion slot options, but they also have features integrated directly into the motherboard, eliminating the need for so many expansion cards....

How Speakers Work Speakers make sound by vibrating, which is another way of saying sound is the product of tiny airwaves. To produce airwaves of a certain loudness or frequency, the speakers that produce those airwaves require a certain amount of power. Speakers that connect to an AV receiver are passive speakers, meaning they do not have a built-in power source, also known as an amplifier. Without connecting to an amplifier, the speakers have no source of energy to vibrate or “drive” the speakers and reproduce the sounds being fed into them....

What Was Retrovision? Retrovision was a free movie streaming site much like other ones you might have used, such as Crackle, Popcornflix, Vudu, etc. There were films in various genres, including Adventure, Comedy, Cartoons, Crime, Drama, Horror, Sci-Fi, Westerns, and War. Some popular areas of the site were called Beverly Hillbillies, Lucille Ball, Cult Films, and One Step Beyond. Classic TV shows could also be streamed here; most were from the ’40s to ’90s....

Send an Anonymous Text With SMS Gateways The simplest way to text anonymously is to use SMS gateways, which only require an email address. All major carriers offer a service where your phone number also serves as an email address, and any emails sent to that address are delivered to your phone as a text. For example, if your friend’s number is 555-867-5309, and they’re on Sprint, you can send an email from your email address to 5558675309@messaging....

This is possible through Boolean operators such as AND, OR, NOT, and NEAR, as well as the symbols + (add) and - (subtract). When you include an operator in a Boolean search, you’re either introducing flexibility to get a wider range of results, or you’re defining limitations to reduce the number of unrelated results. Boolean Meaning George Boole, an English mathematician from the 19th century, developed an algebraic method that he first described in his 1847 book, The Mathematical Analysis of Logic and expounded upon in his An Investigation of the Laws of Thought (1854)....

You Already Use Databases You may not realize it but you encounter the power of databases all the time in your daily life. For example, when you log into your online banking account, your bank first authenticates your login using your username and password and then displays your account balance and any transactions. A database operating behind the scenes evaluates your username and password combination and provides access to your account....

What Is a JSX File? A file with the JSX file extension is an ExtendScript script file. JSX stands for JavaScript XML. These files have been written in the ExtendScript scripting language, which is similar to JavaScript and ActionScript but supports some additional functions. JSX files are used for writing plug-ins for Adobe Creative Suite software like Photoshop, InDesign, and After Effects. The file extension .JSXBIN is used when a JSX file is saved in binary....

What Is an F4V File? A file with the F4V file extension is a Flash MP4 video file, sometimes called an MPEG-4 video file, that’s based on the Apple QuickTime container format. It’s similar to the MP4 format. This format is also similar to FLV, but since the FLV format has certain limits with H.264/AAC content, Adobe developed F4V as an upgrade. However, F4V doesn’t support some of the video and audio codecs in the FLV format, like Nellymoser, Sorenson Spark, and Screen....

What Is an Intrusion Protection System? Intrusion Protection Systems are a control system; they not only detect potential threats to a network system and its infrastructure, but seeks to actively block any connections that may be a threat. This is different to more passive protections like intrusion detection systems. An intrusion prevention system constantly monitors network traffic, specifically at individual packets, to look for any possible malicious attacks. It collects information about these packets and reports them to system administrators, but it also makes preventative moves of its own....

What Is Binary Code? Binary is a base-2 number system representing numbers using a pattern of ones and zeroes. Early computer systems had mechanical switches that turned on to represent 1, and turned off to represent 0. By using switches in series, computers could represent numbers using binary code. Modern computers still use binary code in the form of digital ones and zeroes inside the CPU and RAM. Binary numbers consist of a series of eight “bits,” which are known as a “byte....

What is Data Mining? Data mining is also referred to as data discovery or knowledge discovery. It is the practice of extracting valuable information about a person based on their internet browsing, shopping purchases, location data, and much more. The process involves taking massive amounts of information and pulling tiny details from it to use in a variety of marketing and sales campaigns. How Do Companies Get Information About Me? Data mining companies gather this information using email lists you’ve signed up for, your Facebook likes, Google search history, and a dozen other sources, including some you would never think of....

History of Dithering Mostly forgotten, one of the earliest uses for dithering was in World War II for bomb trajectories and navigation. That use differs greatly from dithering as we know it today. Used commonly in the printing press for both newspapers and comic books, dithering came into its own with the advent of the World Wide Web. Before the internet had become the polished eye candy we know today, almost all sites were text-based....

This EXE file sits in the Windows taskbar by the clock and other notification area items. It starts with Windows by default and will display messages related to storage devices that are connected to the computer. When selected, the Intel RST tool will open. Unlike some files that are necessary in order for Windows to remain stable, IAStorIcon.exe has a limited purpose and can usually be ended without causing problems....

Generally, PCI Express refers to the actual expansion slots on the motherboard that accept PCIe-based expansion cards and the types of expansion cards themselves. PCI Express all but has replaced AGP and PCI, both of which replaced the oldest widely-used connection type called ISA. While computers may contain various types of expansion slots, PCI Express is considered the standard internal interface. Many computer motherboards today are manufactured only with PCIe slots....
