There are two types of linking: dynamic linking uses a dynamic link library, allowing executable modules. Static linking uses a static link library. The linker obtains all referenced functions from the static link library LIB, and puts the library with the code in the executable file. The difference between lib and dll is as follows: 1 lib is used at compile time, dll is used at run time. If you want to complete the compilation of the source code, you only need lib; if you want to make the dynamically linked program run, you only need dll.
Using statically compiled lib files, there is no need to hang the dynamic library when running the program. The disadvantage is that the application is relatively large, and the flexibility of the dynamic library is lost. When a new version is released, a new application must be released. DLL contains the actual function and data. In the executable file of the application, what is stored is not the called function code, but the address of the corresponding function code in the DLL, thereby saving memory resources.
There are two files to pay attention to when using lib: 1. With technology getting upgraded year after year, it is also making the process of creation of programs and software important, and it is important to know which type of file a person wants his or her work to go in and analyze the advantages and disadvantages of each component that is used in the building of the software. These are used by designers and coders and generally, not by the average computer users.
They require a code or any particular sort of program or software to open these types of files. LIB is a static link library, which runs on the complied time of the operating system. It settles in an electronic device as a single file, which is comparatively larger than other libraries but, because of this aspect, saves the user from versioning problems.
DLL is a dynamic link library that compiles at run-time by the loader. It saves memory and space of the computer or drive, which is an advantage over any static link library like LIB. Each compiler does it differently. Vinodhini Ramasamy Vinodhini Ramasamy 4 4 silver badges 3 3 bronze badges. One other difference lies in the performance.
