Bit: A Bit is the smallest unit of data that a
computer uses. It can be used to represent two states of information, such as
Yes or No.
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. bit byte kilobyte
Kilobyte: A Kilobyte is approximately 1,000 Bytes,
actually 1,024 Bytes depending on which definition is used. 1 Kilobyte would be
equal to this paragraph you are reading, whereas 100 Kilobytes would equal an
entire page.
Megabyte: A Megabyte is approximately 1,000 Kilobytes.
In the early days of computing, a Megabyte was considered to be a large amount
of data. 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. bit byte kilobyte
Gigabyte: A Gigabyte is approximately 1,000 Megabytes.
A Gigabyte is still a very common term used these days when referring to disk
space or drive storage. 1 Gigabyte of data is almost twice the amount of data
that a CD-ROM can hold. But it's about one thousand times the capacity of a
3-1/2 floppy disk. 1 Gigabyte could hold the contents of about 10 yards of
books on a shelf. 100 Gigabytes could hold the entire library floor of academic
journals.
Terabyte: A Terabyte is approximately one trillion
bytes, or 1,000 Gigabytes. There was a time that I never thought I would see a
1 Terabyte hard drive, 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 good 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. That's
a lot of data.
Petabyte: A Petabyte is approximately 1,000 Terabytes
or one million Gigabytes. It's hard to visualize what a Petabyte could hold. 1
Petabyte could hold approximately 20 million 4-door filing cabinets full of
text. It could hold 500 billion pages of standard printed text. It would take
about 500 million floppy disks to store the same amount of data. bit byte kilobyte
Exabyte: An Exabyte is approximately 1,000 Petabytes.
Another way to look at it is that an Exabyte is approximately one quintillion
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 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. bit byte kilobyte
Brontobyte: A Brontobyte is (you guessed it)
approximately 1,000 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 Brontobytes! Not sure why this term was created. I'm
doubting that anyone alive today will ever see a Geopbyte hard drive. One way
of looking at a geopbyte is 15267 6504600
2283229 4012496 7031205 376 bytes!
