what is difference between .dll and .exe files?

Answer Posted / milind patil

dll means "Dynamic Link Library". Exe means "Executables"
.Exe
1. These are outbound file.
2. Only one .exe file exists per application.
3. .Exe cannot be shared with other applications.
4. .Exe Can Run On its own
.dll
1. These are inbound file .
2. Many .dll files may exists in one application.
3. .dll can be shared with other applications.
4. .dll cannot Run on its own

The DLL is an inprocess component but exe is outprocess
component. When system launches an exe, a new process is
created , for DLL a new process is not created.

DLL is a WIN 32 LIBRARY file, whereas the exe is a WIN32
executable file.

DLL can be reused and versioned. DLL reduces storage space
as different programs/files can use the same dll.

DLL does not have a main function. DLL binding occurs at
runtime. That is why its called "Dynamic Link" library.

EXE has a single main entry point.
