Explain Linker and Loader..

Answer / anusha.r

The basic job of any linker or loader is simple: it binds
more abstract names to more concrete names, which permits
programmers to write code using the more abstract names.
That is, it takes a name written by a programmer such as
getline and binds it to ``the location 612 bytes from the
beginning of the executable code in module iosys.'' Or it
may take a more abstract numeric address such as ``the
location 450 bytes beyond the beginning of the static data
for this module'' and bind it to a numeric address

Explain Linker and Loader..

Answer / vadivel t

Linker is a stage before loader. Linker is a person who is
responsible for linking the different object file and the
outcome will be a executable file. Loader is a person who
reads the content of the executable file and place it into
memory. This code shall be executed when the operating
system control is coming to the loaded program.

Computers basicly work with binary numbers, people speak their native languages, so, programming languages are for communication between people and computers. If you say: Add 2 and 3 and then substract 1 from it, I doubt that computer would understand anything (maybe in some programming language it would). So, you need to translate your source code into a format that computer understands, so you need a compiler, which translates a programming language to co called object code. But object code is not yet the language a computer understands and executes directly. So it needs a linker which will make an executable file that containts instructions in so called machine language; a machine language is a set of operations coded into binary numbers which processor understands. All binary instructions have it's structure and it's published by a processor manufacturers. You can look for it on say Intel's site and see how do they look like. I can't give a satisfactory answer for loaders at the moment so please search Google as a beginning step.
