What Is an NEF File? An NEF file is a Nikon Raw Image file. It is an abbreviation for Nikon Electronic Format, and is used solely on Nikon cameras. Like other RAW image files, NEF files retain everything captured by the camera before any processing is undergone, including the metadata like the camera and lens model. The NEF file format is based on TIFF. How to Open an NEF File Windows users with the right codec on their computer can display NEF files without any additional software....

ReadyBoost is a feature first introduced in Windows Vista where the operating system improves system performance by dedicating unused hardware space as virtual RAM—the SFCACHE file holds the data stored in this virtual RAM space. While physical RAM is the fastest way to access data, using flash memory is even faster than accessing the same data on a hard drive, which is the whole idea behind ReadyBoost. How to Open an SFCACHE File SFCACHE files are part of the ReadyBoost feature and should not be opened, deleted, or moved....

What Is Apple TV? Apple TV streams movies and TV shows to your HDTV, similar to Roku and Google’s Chromecast, but that is only one feature. You can also listen to and watch podcasts on it, play games, stream music, and much more. It all depends on the apps you install. Some programs are free, some cost money, and some are free to download but have a service you have to buy to use it (e....

Blu-ray vs. DVD DVD technology improved on previous formats, such as VHS and Laserdisc, in terms of the TV viewing and listening experience. Still, DVD isn’t a high-definition format. Its limitations became noticeable as HDTV emerged, TV screen sizes increased, and video projectors became more common. Blu-ray aimed to answer DVD’s shortcomings. It allows you to see more depth, a wider range of color shades, and more image detail. DVD uses red laser technology....

DNS is often referred to as the internet’s phone book because it converts easy-to-remember hostnames like www.google.com, to IP addresses like 216.58.217.46. This takes place behind the scenes after you type a URL into a web browser’s address bar. Without DNS (and especially search engines like Google), navigating the internet wouldn’t be easy since we’d have to enter the IP address of each website we want to visit. How Does DNS Work?...

What seek time is not is the total amount of time it takes to copy a file to another hard drive, download data from the internet, burn something to a disc, etc. Although the seek time does play a role in the total time it takes to complete tasks like these, it’s nearly negligible when compared to other factors. Seek time is often called access time, but in reality, the access time is a bit longer than the seek time because there exists a small latency period between finding data and then actually accessing it....

What Is ADC? All DSLR and point-and-shoot cameras employ sensors that consist of pixels with photodiodes. These components convert the energy of photons into an electrical charge. That charge is converted to a voltage, which is then amplified to a level at which it can be processed further by the digital camera’s Analog to Digital Converter (variously called the ADC, AD Converter, and the A/D Converter). The ADC is a chip inside your digital camera and its job is to classify the voltages of the pixels into levels of brightness and to assign each level to a binary number, consisting of zeros and ones....

Why Is it Called Wireless N? The term Wireless N came into popular usage starting in 2006 as network equipment manufacturers began developing hardware incorporating 802.11n technology. Until the 802.11n industry standard was finalized in 2009, manufacturers could not rightly claim their products as 802.11n compliant. The alternative terms Draft N and Wireless N were invented to distinguish these early products. Wireless N remained in use later, even for fully compliant products, as an alternative to the numeric name of the Wi-Fi standard....
