Trends in Language
Bandwidth and data storage increases again and again, from kilobytes to megabytes to gigabytes. Language to describe these increasing metrics are as follows:
A bit is either a 1 or a 0
A byte is 8 bits
kilobyte is actually 1024 bytes.
1 Gigabyte is over one billion bytes (1,000,000,000)
1 Terabyte is over one trillion bytes (1,000,000,000,000).
1 Petabyte: over 1,000,000,000,000,000 bytes
1 Exabyte: over 1,000,000,000,000,000,000 bytes
1 Zettabyte: over 1,000,000,000,000,000,000,000 bytes
1 Yottabyte: over 1,000,000,000,000,000,000,000,000 bytes
From Roy William's website at CalTech's Center for Advanced Computing Research
1 Megabyte: One small novel OR one 3.5 inch floppy disk
|5 Megabytes: The complete works of Shakespeare OR 30 seconds of TV-quality video|
A pickup truck filled with paper OR A symphony in high-fidelity sound OR A movie at TV quality
|2 Gigabytes: 20 meters of shelved books OR A stack of 9-track tapes|
|20 Gigabytes: A good collection of the works of Beethoven|
the X-ray films in a large technological hospital OR 50,000
trees made into paper and printed
|2 Terabytes: An academic research library|
|10 Terabytes: The printed collection of the US Library of Congress|
|1 Petabyte: 3 years of Earth Observing System satellite data (2001)|
|2 Petabytes: All US academic research libraries|
|200 Petabytes: All printed material|
|5 Exabytes: All words ever spoken by human beings|
6 - Yottabyte - All words ever spoken by politicians - sorry just kidding.
The introduction of
Serial ATA an industry standard interface witch is replacing
means that future memory devices will be capable of being accessed by most
hardware. Serial ATA utilises 48bit addressing as standard, which means it can
access up to 144 petabytes or over 100,000 gigabytes of storage, which should be
enough for anyone.
