data transfer instruction...

Description

Q1.define data transfer instruction:Data transfer instructions cause transfer of data from one location to another without changing the binary information content. The most common transfers are between memory and processor registers, between processor registers and input or output, and between the processor registers themselves. Data transfer instruction must specify The location of the source and destination operand Length of the data to be transferred The addressing mode The most common data transfer instructions are move, store, load, exchange, clear, set, PUSH, POP

Q2.define data manipulation instruction:Data manipulation instructions perform operations on data and provide the computational capabilities for the computer. The data manipulation instructions in a typical computer are usually divided into three basic types: 1. Arithmetic Instructions 2. Logical and Bit Manipulation Instructions 3. Shift Instructions Q3.define arithmetic instruction:Most machines provide the basic arithmetic operations addition, subtraction, multiplication, and division. Some Single-OPerand instructions are (i) Absolute (ii) Negate (iii) Increment (iv) Decrement...
