Which of the following is a function of absolute Loader besides loading?
Which of the following is a function of absolute Loader besides loading?
The correct option is D All of these
Allocation, linking, relocation
are function of absolute loader besides loading.
Absolute loader:-
An absolute loader is
the simplest of loaders. Its function is simply to take the output of the
assembler and load it into memory. The output of the assembler can be stored on
any machine-readable form of storage, but most commonly it is stored on punched
cards or magnetic tape, disk, or drum.
Loader:-
A loader is a system
program, which takes the object code of a program as input and prepares it for
execution. Programmers usually define the program to be loaded at some predefined
location in the memory. But this loading address given by the programmer
is not being coordinated with the OS.
Relocation:-
Relocationis the process of
assigning load addresses to position-dependent, but locatable code of a program and adjusting the code and data in
the program to reflect the assigned addresses.
Linking:-
Linkeris a program that takes one or more
objects generated by a compiler and combines them into a single executable program.
Loader is the part of an operating system that is responsible for loading
programs from executable into memory, preparing them for execution and then
executing them.
