Maybe think twice the next time you try to talk tech.
A study has found that one in five Americans think that a Blu-ray is a sea animal, and one in 10 think the coding language to build websites, HTML, is a type of sexually transmitted infection.
The study was conducted by Vouchercloud.net, a coupons website looking to see how well its users know their tech jargon.
A spokeswoman for the company told the LA Times: “It seems that quite a few of us need to brush up on our tech definitions.”
On top of the hilarity of the HTML and Blu-ray confusions, there were a few more humorous findings.
— Nearly half thought that a “motherboard” was “the deck of a cruise ship,” not the main circuit board of a computer.
— A quarter thought that the measurement unit “gigabyte” was an insect commonly found in South America.
— Nearly a quarter believed that the audio format “MP3” was a “Star Wars” robot.
— 15 percent thought that a computer program, or “software,” was what you call comfortable clothing.
— 12 percent answered that “USB” is an acronym for a European country — not a connection port on your computer.
Ironically, 61 percent of those surveyed believed that having good tech knowledge was extremely important.
