Compilers and Assemblers:
Compilers convert one high level language into many machine languages, which is why it's "portable" as in it converts into the machine lang for the particular machine/computer
Assembler converts one assembly lang. into only one machine code, thus it's machine-prientated/machine-dependant.
The other difference is that assembler are written for a particular machine code and compilers for a particular HLL.Isn't it?
Lol...this is good revision...
About the camera:
Basically, The camera receives input from sensors like infra-red sensors, light sensors ( measure light intensity), proximity sensors
( measure of distance from object photographed).
Control program uses this data to calculate apertures, shutter speeds, focal length for image.
It then adjusts the autofocus/zoom feature, autoflash feature according to the data recieved from the sensors. It may insert date/ time pic was taken or a name for the pic too.
That should be enuff. Remember going through mark schem for this one...but dunt remember all the other options.
Hope this helps!

Check Sum:
This is an extra digit which is transmitted along with a block of data being sent across a network. It is used to perform a transfer check at the other end. It is often a count of the number of bytes of data being sent. It is retotalled at the other end and compared with the figure received.
My teacher explained it wid the xample COMPUTER8.
But in the mark schemes , the xample given is Hash total (I think). I'm not so clear on what a hash total is either...don't ask...lol
It's supposed to be a "meaningless " total. Dunno how tht makes sense.
