Advantages and Disadvantages of Assembly Language

The assembly language programming needs a good knowledge of machine architecture, operating systems, and programming principles. Assembly language is case insensitive, therefore, the program can be coded either in uppercase or lowercase or a combination of both.

The programs written in assembly language are compact and efficient, which have to be converted to machine code for execution and it is performed by the translator known as an assembler.

The Advantages of Assembly Language

  • They generate small and compact execution modules.
  • They have more control over hardware.
  • They generate executable modules and run faster.
  • Machine language programs can be replaced by mnemonics that are easier to remember.
  • Efficient use of memory.
  • It is not necessary to keep track of memory locations.
  • The speed is faster.
  • Easy to insert and delete data.
  • Oriented towards hardware.
  • The same result can be achieved with fewer instructions.

The Disadvantages of Assembly Language

  • Machine-dependent.
  • lengthy code.
  • error-prone (likely to generate errors).
  • On small-sized computers, such programs cannot be executed.
  • Coding or writing the program takes a lot of time, as it is more complex.
  • The syntax is difficult to remember.
  • Programs cannot be transferred between computers of different makes.
  • SDKs (System Development Kits) are not available.
