what is difference between static library and dynamic library?

Static libraries, while reusable in multiple programs, are locked into a program at compile time. Dynamic, or shared libraries on the other hand, exist as separate files outside of the executable file. ... In contrast, a dynamic library can be modified without a need to re-compile.

In python, A dynamic array is an 'array' from the array module. ... They are not pointers to python objects; this may help avoid some misuse and semantic errors, and modestly improves performance. However, this datatype has essentially the same methods as a python list, barring a few string & file conversion methods.

The main difference between a static and a dynamic language is how it handles its types (or doesn't). ... In dynamic languages, the variable type doesn't need to be defined right off the bat. In other words, in the static language variables are resolved during “compile time” and in the dynamic in the “runtime”.

Static code analysis is done without executing any of the code; dynamic code analysis relies on studying how the code behaves during execution. ... Code analysis in itself produces secure code, but other issues, such as changes within the system build, need to also be considered to produce a secure system.

Static RAM uses a completely different technology. ... So static RAM is fast and expensive, and dynamic RAM is less expensive and slower. Therefore static RAM is used to create the CPU's speed-sensitive cache, while dynamic RAM forms the larger system RAM space.

Static variables: means that they will die with the program itself, this means that the memory will be allocated & never will be released implicitly. Global: these variables can be accessed from anywhere. Local: these variables can be accessed inside their scopes only.

What is the difference between static and dynamic routing? Static needs to have the routing table manually configured while dynamic is configured by sharing routing data.

Static means the IP address never changes as long as you stay with the same provider or same server. Dynamic means the IP address can change from time-to-time. Public means the IP address can be reached via the Internet from any computer in the world.

The most notable difference is scope. The VLA array will only be valid inside the scope where it is declared, while a dynamic array will be available everywhere in the program until you call free() . In practice, VLAs may be faster than dynamic memory, in case the compiler use stack allocation for the VLA.

Static polymorphism is a type of polymorphism that collects the information to call a method during compile time while dynamic polymorphism is a type of polymorphism that collects information to call a method at run time. Thus, this is the main difference between static and dynamic polymorphism.

Static linking is the process of copying all library modules used in the program into the final executable image. ... Dynamic linking is performed at run time by the operating system. Statically linked files are significantly larger in size because external programs are built into the executable files.

In general, dynamic means energetic, capable of action and/or change, or forceful, while static means stationary or fixed. In computer terminology, dynamic usually means capable of action and/or change, while static means fixed.

The behaivour might change even with the same compiler depending on the compilation options and optimization level. Local non- static variables are not initialized -- which typically means they contain garbage. 0 is just as valid a garbage value as any other.

Dynamic linking lets many programs use single copy of executable module. Static linking is done by the linkers in the final step of the compilation whereas the dynamic linking is done at run time by the OS. Statically linked files consume more disk and memory as all the modules are already linked.

Static RAM uses a completely different technology. ... So static RAM is fast and expensive, and dynamic RAM is less expensive and slower. Therefore static RAM is used to create the CPU's speed-sensitive cache, while dynamic RAM forms the larger system RAM space. Learn more about computer memory below.

The variables are declared using var keyword are statically typed. The variables are declared using dynamic keyword are dynamically typed. The type of the variable is decided by the compiler at compile time. The type of the variable is decided by the compiler at run time.

Static libraries, while reusable in multiple programs, are locked into a program at compile time. Dynamic, or shared libraries on the other hand, exist as separate files outside of the executable file. ... A static library, however, is untouchable because it lives inside the executable file.
