(Review) In a typical computer system (not a simulated one) where does the assembler place the bit patterns it creates?

### A good answer might be:

In an object module, stored as a disk file.

# End of Chapter

With the SPIM simulator the object module step is skipped. The assembler puts the bit patterns directly into (simulated) main memory. To end SPIM, click on File; exit in the menu bar.
