All a BYTE is a partical on hard drive platter, when its equal to 1, its storing info, and its magneticly charged, when a byte is equal to 0, its storing no info, and isnt magneticly charged, so 1 decobyte (10 bytes) is ten magneticly charged, storing info.
@Dazzerlikestech1 Actually a byte is 8 bit. 1 bit can be either 1 or zero. When storing the information on a hard drive the plate is always magnetized. Whether there's stored ones or zeroes depends on the direction of the magnetization.
And I could could go on. But that lies outside this video to discuss here. The true architecture of a HD is quite complex ;)
@FreerunnerDave You're absolutely correct. What's being displayed is how many bytes you need to have for a (binary/base 2) terrabyte represented in the decimal (base 10) system.
Not too practical for massive computation I would say. Even my early HP handhelds are way faster (and most of them even programmable). There were also electro-mechanical calculators (with an electromotor to do the cranking). Monroe and Facit are the names of manufacturers that come to mind in this respect. Never used them though, for scientific computation they were already on their way back when I was born. But, like the machine shown here: marvelous pieces of engineering.
If I remember correct this one is from about '63 (and the principle of operation almost 100 years older). At that time it was the workhorse for calculations. Very early and expensive desktop electronic calculators were available but extremely rare. Pocket calculators didn't appear until before the 70s.
Rich people or certain employees mostly at big companies did as you say have an electromechanical machine which eased and speedup doing many calculations.
Of course today it's not of much use. But it's a great retro item and I enjoy giving people an electronic calculator ask them to say a number and do a square root - I will then do the square root on the Odhner. Love to see people drop their jaws when I crank out the same number as the electronic calculator ;)
Yes, the electromechanical ones were expensive. Like me, my father is a physicist and he worked at a university. They had some electromechanical machines around there. They were not used that frequently though, because many people considered them too slow and akward to use. The more advanced (scientific and business) electronic handhelds came indeed in the 1970's (HP was the first to offer them, soon followed by Texas Instruments and a whole lot of other companies).
I only knew the electromechanical machines from stories from my dad, they were long gone when I entered university. I have always been curious to watch one in operation though. The interesting thing about youtube is that that has become possible nowadays, there have been some vids of electromechanical machines at work posted as well. Fascinating to watch.
Actually; It's quite simple and elegant. One tooth wheel per digit engages and moves the setting lever above as the digit itself is reset to zero.
More complex is the quotient register with its tens transfer and the mechanism that needs to be aware of direction of first turn after a reset. But it's not /that/ complex. It's more like tricky since all the pieces needs to be timed accurately to the tooth to work properly.
Nothing on this machine is very complicated although is does contain _many_ parts. You can give me one in atoms in a bucket and I'll almost assemble it in sleep.
Far more complex is a machine like the Facit C1-13 because of setting mechanism and many more movable parts. I have one which I'd very much like to give an overhaul like this Odhner. But I've hesitated so far as I'm having trouble figure out how to start as easy as possible. The Odhner you can easily do in small sections.
It's a mechanical calculator - as the description says ;)
They were in use till about the 70's where their popularity declined throughout the decade because electronic calculators then became common and affordable. There were a few variations this is the Odhner type with setting levers. Another popular type was a key-set type. Both has their dis- and advantages.
There's something extremely cool in turning a handle to process data!

HAHA. My old math teacher had one of these. We used to mess around with it when he wasn't looking.

I would enjoy an Odhner calculator much more than my Casio fx-300ES.

I'd imagine the accumulator transfer mechanism is the most complex part of the whole machine.

Facit actually made a fully automatic pinwheel calculator. Don't know how they did it.

Heh, cool. We used to have one those back at home, my half brother's now taken it and managed to track down a manual for it.
