You hear them thrown around all the time when you're buying tech or in programs and on the internet: HDMI, DVI, JPG, HTML, etc., etc. But what do these terms actually mean? Ensuring you're not just nodding your head as the salesman rattles off specs and tech, we help explain the basics for some of the common tech terms - starting off with computers and the internet.
Computers, Software, & The Internet
GB - Bytes are a general unit of measure for digital data. A GB, short for gigabyte, is very approximately 1 billion bytes. and is in practical terms used for calculating capacity in data capacity - whether it's on a hard disk drive, flash drive, memory, etc. - for computers, laptops, tablets, smartphones, etc.
DVI - DVI, short for Digital Visual Interface, is a type of connection commonly used between your computer and your monitor. It's considered the next step up from the old standby VGA cable. Make sure your computer and your monitor both have DVI connections to ensure compatibility, but most non-super-cheap models do now so it's a pretty safe bet.

404 - A 404 in internet terms is when you're surfing the web and come across a page that doesn't exist, or is "not found" as the page might say. This might happen when there's an outdated/broken link or you've mistyped a page URL. It's just a friendly way of saying "hey, there's nothing here at this URL, please try again."

JPEG - A JPEG (commonly seen displayed as a JPG because of the old three letter file extensions from Microsoft) is a file compression method used for digital images. It is most commonly used as the image file format of choice for displaying images on the internet.
USB - Although others had tried and failed, before there was USB there was mostly a smattering of random computer connection types that all were proprietary or device specific. USB came along in the 1990s and changed all that, with its universal (it's not called the Universal Serial Bus for nothing) ability to work with a huge number of devices. You use USB to connect everything from your printer to your mouse to your keyboard to your digital camera and more. It's that useful. It's also extremely frustrating at times to know which direction to plug the cable in.
