 * What is a tetrabyte? **

In years gone by i.e. the 70’s we talked in terms of bytes (a single character) and kilobytes (1024 bytes). Then we went on to megabytes which is 1024 kilobytes. Next came gigabytes or the equivalent of 1024 megabytes. (This is now more than 1 million kilobytes Now we’re seeing **terabytes** when it comes to our computer memory which is,  1024 gigabytes – more than 1 billion kilobytes.  1 page of text is approximately 2KB then there are approximately 500 pages in a megabyte.  This leads us to over 500,000 pages of text in a gigabyte, and more than 500,000,000 pages of text.

As we say to children we have not seen for a while “ My haven’t you grown.”
