Using the metric system 1,000 bytes would be a k, or
kilobyte, but in the computer industry a k is equal to 1024
bytes. That means each of the below metric designations are
approximate for computer terminology. Some medical computers
currently have storage measured in petabytes. Even as devices
have shrunk in size, demand for storage has increased in
inverse proportion.
kilo = thousand
mega = million
giga = billion (There are 1,024 GB in 1 TB.)
tera = trillion (There are 1,498 CD discs in 1 TB)
peta = quadrillion (A human brain can store about 2.5 PB of
data)
exa = quintillion (Almost 11
million 4K movies can fit in 1 EB)
zetta = sextillion
(1,180,591,620,717,411,303,424)
yotta = septillion
