Machine Language Assembly Language High-Level Language Collection of binarySymbolic form of machine Combines algebraic numbersencodedlanguage (i.e. symbolic expressions & symbols taken Data andnames are used to represent from English language instructionsoperations, registers & (ex. Pascal, COBOL memory locations) FORTRAN, …etc) Ex.Ex. Ex MOV AX,A A = A ADD AX, MOV A,AX

Machine Language Assembly Language High-Level Language Directly understood by aAssembler Compiler (or interpreter) computerconverts to machine converts to machine language 1 assembly language 1 HLL instruction = many instruction = 1 machine machine language language instruction instructions Not standard (i.e. differentNot standard (i.e. different Standard (i.e. programs are machine language forassembly language for independent of the machine every ISA for every type of machine) on which they will be Computer family) executed)

Advantages of Assembly Language Performance: A well-written Assembly language program produces a faster, shorter machine language program. For Some applications speed and size is critical Access to hardware: Some operations, such as reading or writing to specific memory locations & I/O ports can be done easily in Assembly but may be impossible by a higher level language. Studying ASM language gain a feeling of the way the computer thinks and the ways that things are happen inside the computer.
