So which is it, independently addressable or independently accessible ?
On an Alpha 21064 these are different values - 8 bits vs 32 bits.

For most people these terms are identical, but there is no point in 
arguing over terminology. Independent here means that separate tasks can
read and write separate elements without intefering with one another. Note
that this means that on the (old) Alpha, a character in a non-packed record
by default takes 32 bits.
