CES 2015: How to Fake Your Way Into Sounding Like a Tech Expert

— -- More than two million square feet of convention floor in Las Vegas has turned into a technology wonderland this week, complete with cutting-edge gadgets and consumer-ready products.

The 2015 International Consumer Electronics Show is a technology bonanza with more than 3,600 companies showing off their wares, but it can be a bit daunting to navigate the tech jargon.

You may know that the price of 4K televisions is going down, but what exactly is it? And what is the Internet of Things?

Here's a cheat sheet to some of the most buzzworthy jargon at this year's CES.

4K

A 4k television stretches 4,000 pixels wide, giving you an incredible resolution.

While the technology has been around for years, prices for 4K televisions are falling, meaning this may be the year you choose to say goodbye to your old 1,080 pixel television.

Several new 4K television models have been unveiled at CES this year, despite the fact that no single television channel is currently available in 4K.

The Consumer Electronics Association expects 23 million 4K televisions will be sold in 2015 -- nearly three times as many as last year.

Connected Car

A connected car is a vehicle that is equipped with Internet access. While many newer model cars have some level of connectivity, they'll only continue to get smarter.

Case in point: General Motors announced this week that it is debuting a new connected car system this year that is so smart it can offer a driver money-saving coupons depending on their destination.

While it's still in development, chip maker NVIDIA showed off a system that will one day allow users to get out of their car and tell it to "Go park yourself."

OLED

While the technology has been around for decades, OLED is still a perplexing term that is finally entering the mainstream tech lexicon.

OLED stands for Organic Light Emitting Diodes. It's a thin layer inside television screens that glows with help from an electric current.

Here's what makes it so great: There's no need for the back light that traditional LED televisions have. This saves power. OLEDs also use their own color filters, resulting in a better picture quality.

Internet of Things

The Internet of Things refers to smart gadgets that are now connected to a device, such as a smartphone or tablet. That means everything from belts to speakers to washing machines.

These everyday items can send and receive information. Think of a crock pot at home that you can control from your iPhone at work or a washing machine that can text you when a load is complete.
