What is the Difference between an EXE and a DLL?

There is a lot to know about computer programm ing. One has to deal with shortcuts and abbreviations to access certain files and programs in the computer and one has to learn more terms which pertains to computer programming to know the twist and turns there is. One question that is being asked by people is about EXE and DLL and what is the difference between an EXE and a DLL. This article will provide brief answers to such question.

Exporting a computer program can be done in two ways, whether in EXE or in DLL. EXE is a shortcut to the term “executable” and this makes the project recognized as a program. This needs an entry point or a code that enables the operating system start the application of the program. EXE has its own memory space. Even though EXE can run independently, this still needs a created process for the program to work properly and run accordingly as desired.

DLL, on the other hand, is a shortcut for the term “dynamic link library”. This is opposed with EXE as a DLL can be run by other programs because it has been created with functions and procedures usable by other applications. This does not require an entry point and this also means it cannot be run independently. What is advantageous with exporting programs with DLL is its reusability, and this entails knowledge by the user on how to operate the names and parameters of the DLL file.

EXE and DLL are distinct in various ways. While EXE would need an entry point, a DLL would no longer need such thing to access the application. EXE is independent while a DLL is not because it relies on other programs and applications for it to run as it is capable of being reused by other functions. With this, a DLL file is advantageous for distributing device driver usage.

Another major difference with EXE and a DLL is their processes and memory space to consume. As stated earlier, EXE is independent and this means it has its own memory space and process. On the other hand, a DLL relies on other applications and programs, so its process and memory space is also shared with the respective program.

What other differences between the two can be cited? While EXE is for single application, a DLL, on the contrary, is for multifunction purposes and an EXE is said to be an Out-Process Component while a DLL is an In-Process Component.

Knowing the distinction between the two will make each user access certain programs according to how it is called upon and will make computer programming an arena for better computer uses and enhancements.
