Wires. Cords. Cables. Coils. Lines. Connectors. Whatever you call 'em, you've probably got plenty of them running between various pieces of beloved hardware. In this wired, wired world of ours, we rely on various cables and connectors to get our technology working in sync, to provide us with internet, with data, with everything from a picture on a display to power. But how many of us really know what's going on in those twisted strands?
To that end, we present to you three common connection technologies - explained, unveiled, and detailed so that you're well versed with the inner workings of your interfaces.
Read on to get the goods on HDBaseT, USB 3.0 and Light Peak!
You can’t swing a dead Na’vi without hitting a new 3D display product these days. Three-dimensional imaging was actually invented in the 1800s, and has been used sporadically in movies since the 1920s, but James Cameron’s sci-fi epic Avatar is bringing it into the mainstream.
Now that 3D is less of a gimmick, TV manufacturers are beginning to incorporate the technology into their products. Panasonic, Samsung, and Sony all announced new 3D TVs at CES this past January. And Avatar could be the best thing to happen to Nvidia and Zalman in their efforts to sell PC gamers on their respective videocards and 3D displays. Market research firm DisplaySearch projects that annual sales of 3D-ready monitors will grow from 40,000 units in 2009 to 10 million by 2018.
So, given that at least some early adopters will buy a 3D display in due time, it’s worth knowing how this visual trickery works. Knowledge is power in the world of upgrading.
Competing technologies may use different implementations, but all 3D video is based on stereoscopic imaging: An illusion of depth is created by presenting a slightly different image to each eye. Each image is of the same object or scene but from a faintly different perspective. Your brain then synthesizes the two images into a spatial representation. The most common 3D applications depend on the viewer wearing either active eyewear (e.g., liquid-crystal shutter glasses) or passive eyewear (e.g., linearly or circularly polarized 3D glasses).
We tend to take things for granted when they work exceptionally well. Take Ethernet, for instance; it’s almost magical: Plug a simple cable into a computer, and it can exchange data with another rig—or many others. Peek behind the curtain and you’ll discover a brilliantly simple yet continually evolving networking system.
But let's make one thing clear: Ethernet technology doesn't actually contain ether.
