Hello. I just finished taking the Lesson 2 quiz and I missed three questions. However, I’m not sure that the answers to these questions actually appear in the textbook. I think it’s possible that at least one of these questions may be unanswerable.
I can find no evidence in the textbook that this is the correct answer:
Question text: “Data travels to the microprocessor on the….”
As far as I know, Apple has been using Intel processors since 2005; the most recent revision date of the textbook is 2012:
Question text: “The processor that is used in Apple computers to run OSX natively is manufactured by….”
I can find no data on what the internal bus speed of the first Pentium processors were anywhere. The book says that “[t]he first Pentium CPUs ran at the same speed as the bus–60Mhz”:
Question text: “The internal bus for the original Pentium series microprocessor is ____ bits in length.”
Clifton, thanks for the email.
1. External data bus is the correct answer. If you look at page 28, second sentence, it states, “The processor is called the CPU (central processing unit) or microprocessor. Therefore, if you look at page 29 it states, “The external data bus connects the processor to adapters…”
2. Motorola is the correct answer. If you look at page 28, last sentence of the first paragraph, it states, “The processor designed by Motorola have been used in Apple computers for years.”
3. 32 is the correct answer. If you look at page 30, second paragraph, it states, “Intel’s 80386D CPU has 32-bit internal…data buses.”
