I was wondering how much Ram you could put in a 128-bit (Operating System)

I know the math. Its 3.4e38. But can someone put than in letters? Or is that not a number yet?

I would think that it would be able to support enough ram to collect all the data ever made in the universe. (not really measurable) or do you think you would need a 256-bit?

That would obviously hold enough ram to collect all the data in the universe and what whatever was before (past) and for septillions of years in the future.

It's fun to think that we will never need 256bit operating system prob for the next 1m years at least (ram wise)

(lots of () )

If you don't feel like making like 100000 "0"s then just say the amount of "0"s

3.4e38 means 3.4 x 10^38, meaning 34, and then 37 zeroes.

If you could up... I'm not going to, but there would be a word to describe what "illion" that is... let's just say, way too much RAM.

"Cinema. There were 4,615 films made world-wide in 1989; at 5MB/sec and 7200 seconds average, that would be 166 terabytes.

Images. There are about 52 billion (thousand million) photographs taken each year in the world. [Mills 1996]. If each of those is a 10 KB JPG, that is 520,000 terabytes, or 520 petabytes, and these are actually all different. Again, less than 1% represent professionally taken or reviewed pictures, probably less than 0.1%. By comparison even the NASA earth observing project, expected to accumulate 11,000 terabytes, [Fargion 1996]. doesn't affect the numbers.

Broadcasting. In the US, we have 1593 television stations. If each sends out 5 MB/sec for 30 million seconds per year, that is over 200 petabytes. However, one might expect that only about 1/10 of the programming is actually different for different stations; that is 20 petabytes of distinct programming, and extrapolated to the world would be 80 petabytes. Radio, by contrast, is insignificant; the US has 6,956 radio stations and if each sends out 30 million seconds per year at 8 KB/sec we would have only 1.7 TB in the United States.

Sound. Sales of recorded music in the US in 1992 were 407 million CDs and 336 million cassettes (and 20 million vinyl disks, still). Assuming 550 MB for each CD and cassette that would be 400 petabytes, much duplicated of course. If the number of different recordings for sale is about 30,000 this would be 15 terabytes in the US and 60 terabytes world-wide.

Telephony The largest storage requirement would come from converting all telephone conversations to digital form. In the US in 1994 there were 500 billion call-minutes of `interlata toll' and there is about 20 times as much local calling, so at 56 kbits/sec this would be 4,000 petabytes of digitized voice. The only thing I am not considering is consumer videotape, on the grounds that much of it is used to record off-the-air TV and duplicates the TV stations.
