Which ONE of the following is a DISADVANTAGE of using dynamically linked library (DLL), compared to using statically linked library?

Choose the correct answer:

Explanation

The correct option is 4. None of the other options.

Explanation:

To understand why none of the first three options represent a disadvantage of a Dynamically Linked Library (DLL), let's analyze each statement by comparing Static Linking and Dynamic Linking:

Statement 1: Executable file size is larger with DLL (Incorrect)
- In Static Linking: The entire library code is copied directly into the application's executable file (.exe). This makes the executable file size significantly larger.
- In Dynamic Linking (DLL): The executable contains only references or stubs to the library functions, not the actual code. The actual code resides in a separate .dll file. Therefore, the executable file size is smaller with DLLs.
Statement 2: RAM usage is larger with DLL (Incorrect)
- In Static Linking: If multiple running programs use the same static library, each program loads its own copy of the library into memory, wasting RAM.
- In Dynamic Linking: A single copy of the DLL can be loaded into the physical memory and shared among multiple executing programs. This makes RAM usage smaller/more efficient with DLLs.
Statement 3: A program cannot take advantage of bug-fixes in the DLL, long after the program is written (Incorrect)
- In Static Linking: Since the library is compiled into the executable, you must recompile and redistribute the entire application to apply a bug fix.
- In Dynamic Linking: You can simply replace the old .dll file with an updated version containing the bug fix. The existing program will automatically use the fixed version without needing a recompilation. This is a major advantage, not a disadvantage.

Since statements 1, 2, and 3 actually state the opposite of how DLLs work (they list the advantages of DLLs as disadvantages), the correct choice is None of the other options.
