The internet is a vast area of a network. 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.
LIB and DLL are both libraries that are used to create the code for various software/applications. 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 vs DLL
The difference between LIB and DLL is that DLL files are reusable as they only need to be linked to the previous DLL, while LIB does not possess this quality and the code has to be copied from the previous to the newer program. Another difference is that LIB comes off as a big large file, but DLL has multiple 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. DLL libraries are considered better than LIBs because of high reusability, performance, and space.
Comparison Table Between LIB and DLL
|Parameters of Comparison||LIB||DLL|
|Regularly used Extension||.lib after the file name||.dll after the file name|
|Definition||LIB files contain a library of information that are static libraries.||DLL contains dynamic link libraries that are used to develop various applications.|
|Length||LIBs are bigger as they compile in one large file.||DLLs are stored as multiple files.|
|Reusability||LIBs cannot be used again, and the whole code has to be copied down.||DLL holds the capability to use the pre-established code just by linking it to the previous one.|
|Type of library||Statically-linked library||Dynamic-link library|
|Performance||LIB libraries are called on compile time.||DLL libraries start during run-time.|
What is LIB?
LIB is a type of file that contains a library of information. It can also contain images, text clippings, and functions referred to by a program. LBB files can either be static libraries that contain object files or import libraries and sometimes be called archives as well.
LIBs do not get open manually. The particular software is needed to crack them that depends from program to program and the version. Since all the components in this library are compiled into one large file, it does not go through the problem of managing different variables, functions, and subroutes that are in it.
There are slightly larger than other libraries, and the code is copied from the main application, unlike dynamic link libraries, where the code can be linked. If there is any change in the execution of the program, changes or editing have to be done in order for it to work. Relink, and Recompilation would be necessary.
What is DLL?
DLL is a dynamic link library, which is linked at run-time by the loader. This gives it an advantage over LIB, which is a static library. They compile at run-time, not only saving the memory but making the performance higher as well.
The main purpose of DLL is to open and go through the function of other different programs. Thye cannot run directly and needs an additional code to open them. Sure, they are useful, but these types of files are not typically opened aside from coders or other technicians as there is nothing much in them for the user, and any error while going through them would result in a problem.
DLL files are compared to EXE files, but the main difference between them is that DLL files cannot be directly opened and executed like EXE. They are super useful for coders as they don’t have to write the code from scratch and use the previous one to save time and energy.
Main Differences Between LIB and DLL
- DLL files can be shared through different programs, but LIB files cannot be shared between programs.
- The performance of the files varies as well. DLL files give off better performance during the run time of the program. LIB, on the other hand, takes a longer time to open as it complied with the files when they clicked, not statically like LIB.
- In DLL, one can directly link to their previously established code, but in a LIB, the code needs to be copied by the person. It gives DLL an advantage over LIB.
- DLL complies with many files. It is not a single one like others, like, Pdf, etc. LIB, on the other hand, LIB, generally comes off in a big large file.
- Because of different files in DLL, it can have ‘versioning’ problems, that is, the management of those various files. Since LIB is a single large file, it doesn’t face this particular problem.
The programs are depended on the type of file that they need in order to be used for opening different files. They both require a vital code in order to open the program, and they should only be edited and saved with suitable software.
One shouldn’t go through these files and especially not download them from the internet as there is a big chance that they are not suitable with a particular software or laptop and, most importantly, might contain viruses in it. In an average computer, these files are already installed, and there is no need to go and look for them. But, if ever does any problem arises, one should only look through a certified developer or coder.
