A byte is a unit of data or digital information in computers. The term 'byte' was coined by Dr Werner Buchholz in July 1956 during the early design phase for the IBM Stretch computer. A byte is abbreviated with a ‘B’. Computer storage is usually measured in byte multiples. For example, 100MB would be 100 megabytes while GB would be gigabytes and more. The latest measure is a terabyte or TB. 1 terabyte is 1000000000000 bytes!
