From OS X: About OS X Recovery


  OS X Internet Recovery
  
  Newer Macs include the ability to start up directly from an
  Internet-based version OS X Recovery. Your Mac automatically uses this
  feature when the Recovery System on the startup drive isn't available.
  For example, if your startup drive encounters an issue, or if your
  startup drive has been replaced or erased. Internet Recovery lets you
  start your Mac directly from Apple's servers. Starting up from this
  system performs a quick test of your memory and hard drive to check
  for hardware issues.
  
  Internet Recovery initially asks you to select a Wi-Fi network and
  enter a network password when needed. Next, Internet Recovery
  downloads and starts from a Recovery System image. From there, you are
  offered the same utilities and options as the Recovery System on a
  startup drive.
