What is DLL?what is dll DLL is what they are called in the Windows environment, and they are the same thing as "shared libraries" or "shared objects" in a Unix or Linux environment.what is dll DLLs are stored in a System or a Library folder, typically with no file extension, although .SO and .SL extensions might be used; when they are stored, they get called on by applications which rely on them as they are needed by those applications. Macs use .DYLIB extensions for subroutines which get linked at computer startup instead of on an as-needed basis.what is dll So, a DLL is a collection of small software programs which are stored and ready to be called up by a larger program that you have running on your computer, such as a program in the Microsoft Office suite. The components of DLLs have several functions including being "device drivers" (calling upon the DVD player to run a movie, the CD player to play music, a printer to print out something, Windows Movie Maker to make movies, and so on). DLL libraries link both to and from applications which use them during a program's execution to enable specific operations rather than being compiled into the main program; they are not loaded into your computer's RAM unless and until they are required. DLL files are used partly to avoid over-burdening your computer's memory. So for instance, the CD burner or CD player will not be loaded while you are still just downloading music onto your computer from the Internet via your subscription music service. Only when you hit the "burn" command will your computer load the needed driver for the task. There might be literally hundreds of subroutines in your computer's DLL library just waiting to be activated when they are needed. Some DLLs are required for you to utilize the Windows and program graphical user interfaces; Some of them are used connect to the Internet or enable you do to certain thing online. Some of them are needed to enable you to use Windows. Some of them are commanded by your computer's audio programs to enable your sound card. Some of them are used by many programs, others are much more exclusive in their applications. Now, if your DLLs are experiencing errors, you can see that these can really cause serious problems with your computer's functionality. Possible symptoms of DLL running errors include: -- Your computer running slower than a sloth with its belly full in a Florida summer. -- Error messages keep coming at you and you cannot find any good reason for it. -- Your computer freezes up or crashes a lot. DLLs are also vulnerable to virus attacks. If your computer has any of the above problems, especially the slothfulness problem, and rebooting and defrag and disk cleanup aren't working, you should suspect a virus. However,you can also find some quality downloadable software on the Internet that will usually give you a free trial so you can test out their DLL error-removal capabilities. This is something most registry repair tools come with these days and will more than likely save you from having to buy a new computer.
