what is dll and how this work ?

Answer 1

dll stands for dinamic link libary, this type of file links to other files. Windows xp is made up of thousands of dlls and at times if one is missing it can screw up the entire computer

Answer 2

A dll is a dynamic link library. Microsoft's term for a library code. It is simply code that can be shared among different programs. Say you write a dll that interfaces with an accounting system. You can install it on a Windows machine, which basically means copy it and then other programs can use the dll to access the accounting system. Programs load the dll into their process space at run time(usually, could be a static link to the dll) and then unload it when they exit.

Answer 3

DLL is a type of a file in windows, its a Dynamic Link Library, which basically means that its a collection of functions that can be used by different parts of windows or different applications. Applications call functions in DLL files. If a DLL file is missing, an application might not work properly because it depends on the function provided by the DLL

Answer 4

dll is an abbreviation or acronym for Dynamic Link Library.
Generally a dll will contain data that is used by another program. some dll files are shared. which means more than one application or program will retrieve information from them.
What each dll does varies greatly.

Answer 5

The original purpose for DLLs was saving both disk space and memory required for applications by storing it locally on the hard drive. In a conventional non-shared library, sections of code are simply added to the calling program; if two programs use the same routine, the code has to be included in both. Instead, code which multiple applications share can be separated into a DLL which only exists as a single, separate file, loaded only once into memory during usage. Extensive use of DLLs allowed early versions of Windows to work under tight memory conditions.

DLLs provide the standard benefits of shared libraries, such as modularity. Modularity allows changes to be made to code and data in a single self-contained DLL shared by several applications without any change to the applications themselves. This basic form of modularity allows for relatively compact patches and service packs for large applications, such as Microsoft Office, Microsoft Visual Studio, and even Microsoft Windows itself.

Another benefit of the modularity is the use of generic interfaces for plug-ins. A single interface may be developed which allows old as well as new modules to be integrated seamlessly at run-time into pre-existing applications, without any modification to the application itself. This concept of dynamic extensibility is taken to the extreme with ActiveX.

While DLLs provide many benefits, they have a number of drawbacks, collectively called "DLL hell". Currently, Microsoft .NET is targeted as a solution to the problems of DLL hell.

Answer 6

dll is Dynamic Link Library your os uses millions of dll's and if you delete them accidentally then you may have to reinstall your os..

Answer 7

dll is DYNAMIC-LINK LBRARY FILE -
They are shared library files for programs.
Don't mess with them or you PC will crash.
