Identify the correct pair from the following :

  • A.Pxl - unit of focus of digital cameras
  • B.HDD - unit of high definition of digital screens
  • C.Kbps - unit of data transfer rate
  • D.Ghz - unit of memory storage on digital devices

Answer: C

The correct pair is Kbps - unit of data transfer rate.

Kbps means kilobits per second, a rate at which data is transmitted over a network or connection.

The other pairs are wrong: a pixel (px) is a picture element, the unit of image resolution, not of focus; an HDD is a hard disk drive, a storage device; and GHz (gigahertz) is a unit of frequency, used for processor clock speed, not memory storage.
