The iPhone 5 is the latest smartphone to hop on-board the LTE (Long Term Evolution) bandwagon, and for good reason: The mobile broadband standard is fast, flexible, and designed for the future. Yet LTE is still a young technology, full of growing pains. Here’s an overview of where it came from, where it is now, and where it might go from here.

Standard video resolutions (scaled to 16:9) showing relative sizes.

Think you’re seeing it all? Not when it comes to digital video. The resolution of current digital video offerings still falls short of what 35mm film offers.

If you've ever wanted to stream music or video around your house—say, from your laptop or your smartphone to your HDTV—you know it can be a bit of a pain. It's often complicated enough that we have to write articles to help you, say, move audio around the house. Wouldn't it be a lot simpler if it moving media around your home network were standardized?

It turns out, it sort of is standardized. At least, there's a dominant standard to allow digital devices to talk to one another for the purposes of streaming video and audio around your home network. That standard is DLNA, or Digital Living Network Alliance.

Speakers—sometimes referred to as loudspeakers—are everywhere. Just looking around my office, I find them inside my iPhone, IP telephone, Apple Cinema Display, headphones, and laptop. Even my alarm clock and my microwave have speakers, not to mention the speakers connected to my stereo. But how do they work?

Three-Minute Tech: IEEE 802.11ac

The first thing you need to know about IEEE 802.11ac—the latest wireless networking standard—is that the standard isn’t actually finished. Today’s 802.11ac routers are based on a second draft. Early 802.11n hardware was likewise based on a draft IEEE standard, but those products were certified to assure consumers they would be compatible. Although this first generation of 802.11ac routers isn’t certified in the same way, no compatibility problems have surfaced to date, so it’s unlikely you’ll encounter problems if you buy one now.

The second thing you need to know is that no manufacturer is selling an 802.11ac USB Wi-Fi adapter today, so your existing laptop computer won’t benefit from the speed boost the new technology promises to deliver. The new 802.11ac routers are backward compatible with the older 802.11n standard, however, so you’ll still be able to connect your existing wireless gear to the new routers, but you won’t gain any performance boost (unless you’re upgrading from a very old router).

Kicking back on the couch to watch a game, enjoy a movie, or lose yourself in the latest episode of Game of Thrones is a great way to relax. However, shopping for an HDTV can be baffling. LED or plasma? 120Hz or 240Hz? HDTV specs are as numerous as they are confusing, but here’s what a few of the most-common terms mean.
