Being a windows PC user for so many years, you must have seen problems that are made in the computer by DLL files. Some times DLL files don’t allow some applications to install in the computer. This problem can be removed by just finding the appropriate DLL file on the internet.
What is a DLL file?
DLL is the acronym for Dynamic link library. It is a set of shared library by the Microsoft corporation. It is a file that helps the application to do certain stuff. It can be shared by multiple processes & application to avoid duplicability. These DLL files consisting of class, functions , variable & other resources like icon , images etc.
Every operating system contains two type of files in them i.e. static library & dynamic library. Static library are linked to the program at compile time while the dynamic library are linked during run time. A dynamic library is an independent file that updates without any interruption of application software.

DLL works in order to save disk space in the computer. One DLL can be useful to many applications. This also helps to improve the performance of programs running either in background or foreground. This property of DLL helps in the modular approach of programming.
As I wrote above that a single DLL is helpful for multiple applications, so you can update any DLL independent of any other application.
