An absolute loader is the simplest type of loader scheme that fits the general model of loaders. The assembler produces the output in the same way as in the 'complier and go loader'. Lost Season 1 Episode 1 Direct Download. The assembler outputs the machine language translation of the source program. Disadvantage: • The programmer has to specify the address to the assembler that where the program is to be loaded. • It is very difficult to realocate in case of multiple subroutine. • Programmer has to remember the address of each subroutine and use that absolute address explicitly in other subroutines to perform subroutine linkage.

The loader is a program which accepts an object code and prepare them for execution.The loader's target language is machine language, its source language is nearly machine lan gugae.loading is ultimately bound with storage management function of operating systems and is usually performed later than assembly or compilation.the period of executions of user program is called execution time.the period of translating user's source program is called assembly or compile time. Load time refers to the period of loading and preparing object program for execution. Loading schemes: 1.Absolute loader.
