Definitions of Computer Architecture and Computer Organization seems confusing
It seems that the important difference between the terms as used here is that computer architecture is about useful things the system can do for its user (the programmer), and that computer organization is about how to build and connect &quot;units&quot; in order to create such a system.
I will first note that your argument here is not correct: while I agree architecture is about organizing and building things, computer architecture is, according to your book, not about building things. Note that &quot;computer architecture&quot; and &quot;architecture&quot; are not the same. A technical term with a definition is what the definition says it is, no more, no less.1 Any relation the name may have with the English language is irrelevant.2
For example, if I define a particular combination of points and lines to be a caterpillar, then a caterpillar is exactly that and any complaint that a combination of points and lines cannot turn into a butterfly is irrelevant.3
According to what the definitions computer architecture and computer organization say, it seems to me that (assuming &quot;integrating functional blocks&quot; and &quot;interconnecting operational units&quot; are interchangeable) Statements 1 and 2 are true, while 3 and 4 are false. I encourage you to work out the details on your own, using the definitions of the terms involved.

1: Or, as Lewis Carroll wrote:

&quot;When I use a word,&quot; Humpty Dumpty said, in rather a scornful tone, &quot;it means just what I choose it to mean—neither more nor less.&quot;

 2: That said, it certainly is annoying when the name of a term seems to outright contradict its definition (cf. the lines in the poem preceding the quoted line of Mr. Dumpty), and I think the particular names chosen for the definitions in your book are not that good, to be honest. Naming concepts is an art in itself and not many good scientists are also good artists, or even want to be. So many concepts have unfortunate names, but if you read a book that uses those names, you will have to live with it.
3: No, I did not make this up. Someone else beat me to it.
