Doesnt for example 0001001=001001=01001=1001?

Blimey I'm no authority on these things but, doesn't a computer need to know when one letter ends and another starts and hence I needs a fixed length for each letter. Otherwise how would it know if 01110 was 01-110 or 0111-0, etc

Computers only work with 1 and 0. They are pretty thick in that respect

Now the secret sale obsession (just for a friend luckily) has died down somewhat... can we get a poster please? Having failed on that front, I want some cheering up. 

Me too.  And my coach is a lot later than I'd hoped - but maybe I won't be so knackered at the end if I get there at a sensible time.

1001 in binary = 9 in decimal, 00001001 also = 9 in decimal, the 0's to the left are redundant data and would not be stored in memory as they hold no value,  it would be inefficient and cost ineffective to store them. 

And back on topic, I would love a huge announcement in regards to a new act, I feel however it will just be regarding shangri la

but if a computer ignored leading zeros, how it would know when one character ended and the next one started? They need fixed length don't they? 8bit, 16bit, etc...

Yes they would, as a zero! Or more precisely, an amount of current low enough to represent the off state.

Sure, you could imagine a compression routine that didn't store those leading zeros, but that would only make sense if the size of the field could be described in fewer bits than the leading zeros. I don't know enough about compression algorithms to say whether that does exist, but I doubt it.

But as for how the raw binary is stored in memory, the leading zeros are there. You may as well say that the leading 1s don't need to be stored.

Mathematically you're right, but that's not quite how computers work when we get so low level.

Some functions may need a logic low to become active. Normally open switches and things like that. Each bit in the register maybe doing a different function. Binary numbers are not just data addresses. We use bit codes to drive some machines.

I would have thought digital to analog converters would need the full data string as well.

Anyway the key numbers are

Thats very interesting; I've just started (2 months in) to work embedded systems module at uni, we've been told by our lecturer that the 0's can be dropped to only store from the most significant bit (? The first 1 as he put it ?) in an effort to increase the efficiency of the retrieval of data.

I shall put this to him on Thursday and see what he has to say!

It is voltage that is the important in logic levels mate.

Come on Glade, Shangri-La, Pilton Palais. ... anyone! Give us an announcement to get us back on track!

Agreed, this is worse than discussing types of bread.
