Question

List the three categories of Assembly Language Instructions, with a brief description of eachcategory. Do not list the individual LC-3 instructions.

Answer 1

The three categories of assembly language instructions are:

1. Data Transfer Instructions: These instructions are used to move data between memory locations and registers. Examples include instructions to load a value from memory into a register or store a value from a register into memory.
2. Arithmetic and Logic Instructions: These instructions are used to perform mathematical operations and logical operations on data stored in registers or memory. Examples include instructions to add or subtract values, or to perform bitwise operations such as AND and OR.
3. Control Flow Instructions: These instructions are used to change the order in which instructions are executed. Examples include instructions to jump to a different location in the program, to call a subroutine, or to return from a subroutine.
