Loading the program will load these objects/libraries as well, and perform a final linking. This approach offers two advantages: Often-used libraries (for example the standard system libraries) need to be stored in only one location, not duplicated in every single executable file, thus saving limited memory and disk space.
For example, Plan 9 from Bell Labs and its successor 9front intentionally avoid dynamic linking, as they consider it to be "harmful". [9] The Go programming language, by some of the same developers as Plan 9, also did not support dynamic linking, but plugin loading is available since Go 1.8 (February 2017). The Go runtime and any library ...
Linking is often referred to as a process that is performed when the executable is compiled, while a dynamic linker is a special part of an operating system that loads external shared libraries into a running process and then binds those shared libraries dynamically to the running process. This approach is also called dynamic linking or late ...
Relocation is the process of assigning load addresses for position-dependent code and data of a program and adjusting the code and data to reflect the assigned addresses. [1] [2] Prior to the advent of multiprocess systems, and still in many embedded systems, the addresses for objects are absolute starting at a known location, often zero.
Loading the program will load these objects/libraries as well, and perform a final linking. Dynamic linking offers three advantages: Often-used libraries (for example the standard system library ) need to be stored in only one location, not duplicated in every single binary.
Historically, all library linking was static, but today dynamic linking is an alternative and entails inherent trade-offs.. An advantage of static over dynamic is that the application is guaranteed to have the library routines it requires available at run-time, as the code to those routines is embedded in the executable file.

Loading a program involves either memory-mapping or copying the contents of the executable file containing the program instructions into memory, and then carrying out other required preparatory tasks to prepare the executable for running. Once loading is complete, the operating system starts the program by passing control to the loaded program ...
