Question
The 8086 and its descendants have one data bus and one address bus, implying that memory and I/O share the same data bus and address bus. Whether an access is intended for memory or I/O is determined by ________ bits such as S0, S1, and S2 (for example). The 8086 assembler, _______, is converts the user assembly language program into ________, which the processor understands. This assembler uses the _______ symbol to identify a label used in the code segment, and a _______symbol to denote that the rest of the line (to the right of the symbol) is a comment. Intel x86 assembly language instructions have an _________, which is an action, and from 0 to 3___________, which specify the objects that the action takes place on. The first object is the (source/destination circle one), while the remaining objects form the (source/destination circle one). The rules for these objects are that they must be(different sizes/source must be smaller than the destination circle one), and both source and destination can't be _________ To clear a register such as BX in x86 assembly code, the best method is to use the instruction_________, This type of instruction is better instruction because (arithmetic/looping/CX register/logical circle one) instructions are more efficient.Explanation / Answer
