Most ISA's have an instruction that simply does nothing, called NOP, which is short for NO OPeration (the O is from either word). The instruction is fetched, decoded, and executed so the PC, IR, MAR, and MDR are changed as a result. However, NOP does not change the contents of the general purpose registers, memory, or even the condition codes. Additionally, NOP continues execution with the instruction right after the NOP. Which of the following LC-3 instructions could operate as a NOP? A.) 0000 000 000001100 [Select] B.) 1110 000 000000000 [Select] [Select] fails as a NOP works as a NOP

Similarities and differences between User Stories and Use Cases a. Similarities b. Differences 3. When and how to use User Stories, Use Cases, both, and neither a. Under what conditions should we use User Stories b. Under what conditions should we use Use Cases c. Under what conditions should we use both d. Under what conditions should we use something else to determine requirements 5. Summary 6. Works Cited
