Answer 1

I believe only the first statement is correct because the second one claims that the linker replaces absolute references in an object, which is incorrect; the linker always generates relocatable addresses.

Answer 2

the linker produces absolute machine code,but here it says it replaces. So I is true only.Maybe

Answer 3

I think 3 is right anwer.

Answer 4

In computer science, a linker is a computer program that takes one or more object files generated by a compiler and combines them into one, executable program.

Computer programs are usually made up of multiple modules that span separate object files, each being a compiled computer program. The program as a whole refers to these separately compiled object files using symbols. The linker combines these separate files into a single, unified program, resolving the symbolic references as it goes along.

so only staement 1 is true

Answer 5

answer:- (a)

reason: a linker is a computer software that combine 2 or more file generated by compiler into a single executable file.

so its function is to combine several object modules into a single load module.

Answer 6

both statements are correct 

1st statement is easy, let's check 2^nd statement 

The linker resolves dependencies between the object files and static libraries while the loader resolves dependencies between the executable and any shared library.

the function of a linker is to replace absolute references in an object module with symbolic references

here symbolic ref means the logical address, not a reference that actually points to a physical memory location 

That's why we call it a linker
