Basic elements of Assembly language:

Any Assembly language which consists 3 types of instruction statements that are used to define the program operations:

• Data sections
• Op code mnemonics
• Assembly directives

Data sections

There are many instructions used to define data elements to hold data and variables. They define what type of length, data and alignment of data. These instructions may also define whether the data is obtainable from outside programs (programs assembled separately) or only to the program in which the data section is defined.
