Tera
'''Tera''' (symbol:
T) is a
prefix in the
SI system of units denoting
1012, or 1 000 000 000 000.
Confirmed in 1960, it comes from the
Greek τέρας, meaning
monster.
In
computer science tera can sometimes mean 1 099 511 627 776 (2
40), instead of 1 000 000 000 000 especially when used to prefix the
byte, giving a
terabyte. To avoid this ambiguity, the term
tebibyte has been introduced for 2
40 bytes, but this is not yet widely used.
