COMPUTER FUNDAMENTALS

Detailed explanation-1: -In computing, a linker or link editor is a computer system program that takes one or more object files (generated by a compiler or an assembler) and combines them into a single executable file, library file, or another “object” file.

Detailed explanation-2: -A compiler takes our source code and generates the corresponding assembly code. An assembler converts the assembly code to the machine code. A linker merges all the machine-code modules referenced in our code, whereas a loader moves the executable to RAM and lets it be executed by a CPU.

Detailed explanation-3: -A linker script is a file that tells the linker which sections to include in the output file, as well as which order to put them in, what type of file is to be produced, and what is to be the address of the first instruction.

Detailed explanation-4: -Linking − The linker is produces the final compilation output from the object files the compiler produced. This output can be a shared (or dynamic) library or an executable. It links the object files by replacing the undefined references with the correct addresses.
