3 Answers 3. Earphones/earbuds are those worn in the ears without a headband. While they come in pairs, one can have an earphone/earbud in one ear, leaving the other dangling. Some, but not all, headphones have a band. The earphones or earcups (you may not find this in the dictionary) that make up the pair are worn over or on the ears. Thus, one can wear headphones with only one earcup/earphone on.
Development of Swift started in July 2010 by Chris Lattner, with the eventual collaboration of many other programmers at Apple. Swift took language ideas from Objective-C, Rust, Haskell, Ruby, Python, C#, CLU, and far too many others to list.
The Arizona-based company boasts a fleet of 16,000 trucks and was founded in 1966. The company first began by transporting steel from the Los Angeles to Arizona. They also transported cotton from Arizona back to Southern California for export. Over the years, Swift has acquired more than 11 different motor carriers.
