1. Null & Lobur, Chapter 4: #7(a,c,e,f,g), #8, #10, #11
   Notes: For #7, assume that the memory is byte addressable. For #7(f,g) indicate the module and the address within the module where address 14 would be found. For #8(d) give the decimal value. For #11, be sure to discuss in detail the role played by the IR and the PC.
2. Write a paragraph or two comparing and contrasting, in your own words, the roles of the compiler, the linker and the assembler. To fully answer this question you should read several outside sources such as texts in the library or web sites. Be sure to cite the sources that you use.
