Section 7.5 The Little Computer - Assembly
The Little Computer supports an
assembly language that can make it easier for humans to write and read programs. In addition to replacing numeric commands like “1XX” or “902” with abbreviated English commands like “ADD” or “OUT”, Little Computer assembly allows us to think at a slightly more abstract level. Instead of remembering specific memory addresses so we can say
“add the value from location 10” , we can name memory locations and then say things like
“add X” . This video introduces it:
Checkpoint 7.5.1 .
What advantages do symbolic names provide in Little Computer assembly? Select all that apply.
They let a programmer refer to a meaningful name instead of remembering a specific memory address.
They allow references to remain correct when the program’s layout or size changes.
They let the processor skip the process of executing instructions.
They make memory locations store more than one value at a time.
They remove the need for instructions to be represented in machine code.
Checkpoint 7.5.2 .
After a Little Computer assembly program is assembled, how does the computer run it?
It executes the corresponding machine instructions.
It reads the assembly words as ordinary English sentences.
It sends the program directly to a high-level language compiler.
It runs only the labels and skips the instructions.
Checkpoint 7.5.3 .
