Types of Instructions | Data Transfer Instructions | Data Manipulation Instructions | Program Control Instructions

Types of Instructions:
Data Transfer Instructions: 
Data transfer instructions cause transfer of data from one location to another without changing the information content.
The common transfers may be between memory and processor registers, between processor registers and input/output.
Data Manipulation Instructions: Data manipulation instructions perform operations on data and provide the computational capabilities for the computer. There are three types of data manipulation instructions: Arithmetic instructions, Logical and bit manipulation instructions, and Shift instructions.
Program Control Instructions
Program control instructions specify conditions for altering the content of the program counter, while data transfer and manipulation instructions specify conditions for data processing operations. The change in value of a program counter as a result of the execution of a program control instruction causes a break in the sequence of instruction execution.
