180.

A DLL can run independently

DLL is an out-process file and EXE is an in-process file

exe file is a excutable file which runs in a seperate process which is managed by OS

dll file is a dynamic link library which cannot be used in exe files

EXE:
Its a executable file
There is only single main entry
When a system launches new exe, a new process is created
The entry thread is called in context of main thread of that process.

DLL:
Its a Dynamic Link Library
There are many entry points.
The system loads a DLL into the context of an existing thread
