This is based on the IBM Dictionary of computing method to describe the disk storage. Let's find out more detail of the above terms:
Bit: A Bit is the smallest unit of data used by a computer. It can be used to represent two states of information. For example- Yes or No, right or wrong etc.
Byte:
A Byte is equal to 8 Bits. A Byte can represent 256 states of
information, for example, numbers or a combination of numbers and
letters. 1 Byte could be equal to one character. 10 Bytes could be equal
to a word. 100 Bytes would equal an average sentence.
Kilobyte: A
Kilobyte is approximately 1,000 Bytes, actually 1,024 Bytes depending
on which definition is used. 1 Kilobyte might be equal to this paragraph
you are reading, whereas 100 Kilobytes would equal a full page like
this one.
Megabyte: A
Megabyte is approximately 1,000/1,024 Kilobytes. In the early days of
computing, a Megabyte was considered to be a large amount of data may be
similar to 1 GB of today. These days with a 500 Gigabyte hard drive on a
computer being common, a Megabyte doesn't seem like much anymore. One
of those old 3-1/2 inch floppy disks can hold 1.44 Megabytes or the
equivalent of a small book. 100 Megabytes might hold a couple volumes of
Encyclopedias. 600 Megabytes is about the amount of data that will fit
on a CD-ROM disk.
Terabyte: A Terabyte is approximately one trillion bytes, or 1,000/1,024 Gigabytes. Now one and two terabyte drives are the normal specs for many new computers. To put it in some perspective, a Terabyte could hold about 3.6 million 300 Kilobyte images or maybe about 300 hours of high quality video. A Terabyte could hold 1,000 copies of the Encyclopedia Britannica. Ten Terabytes could hold the printed collection of the Library of Congress.
Exabyte: An
Exabyte is approximately 1,000/1,024 Petabytes. Another way to look at
it is that an Exabyte is approximately one Quintilian bytes or one
billion Gigabytes. There is not much to compare an Exabyte to. It has
been said that 5 Exabytes would be equal to all of the words ever spoken
by mankind.
Zettabyte:
A Zettabyte is approximately 1,000/1,024 Exabytes. There is nothing to
compare a Zettabyte to but to say that it would take a whole lot of ones
and zeroes to fill it up.
Yottabyte:
A Yottabyte is approximately 1,000 Zettabytes. It would take
approximately 11 trillion years to download a Yottabyte file from the
Internet using high-power broadband. You can compare it to the World
Wide Web as the entire Internet almost takes up about a Yottabyte.
Brontobyte:
A Brontobyte is (you guessed it) approximately 1,000/1,024 Yottabytes.
The only thing there is to say about a Brontobyte is that it is a 1
followed by 27 zeroes!
Geopbyte:
A Geopbyte is about 1000/1,024 Brontobytes! Not sure why this term was
created. I'm not sure whether someone alive today will ever see a
Geopbyte hard drive. But world is changing so rapidly that it might not
be impossible. One way of looking at a geopbyte is 15267 6504600 2283229
4012496 7031205 376 bytes. Can you imagine how much time required to
use this term practically?!
Now you should have a good understanding of megabytes, gigabytes, terabytes and everything in between. Keep in touch to find out more in the future. Thanks.
