System Software
Notes In assembly language, symbols are used in place of absolute addresses to represent memory
locations.
Mnemonics are used for operation code, i.e., single letters or short abbreviations that help the
programmers to understand what the code represents. For example, MOV AX, DX.
Here mnemonic MOV represents 'transfer' operation and AX, DX are used to represent the
registers.
Advantages
(a) Assembly language is easier to use than machine language.
(b) An assembler is useful for detecting programming errors.
(c) Programmers do not have to know the absolute addresses of data items.
(d) Assembly languages encourage modular programming.
Disadvantages
(a) Assembly language programs are not directly executable.
(b) Assembly languages are machine dependent and, therefore, not portable from one machine
to another.
(c) Programming in assembly language requires a higher level of programming skill.

15. Assembly languages are ……………………. dependent and, therefore, not portable from
one machine to another.
