What is difference between Static analysis and Dynamic analysis?

Static analysis can be seen as a stricter check of syntax made by an advanced compiler (that will not produce binary code but error messages).
Dynamic analysis is a specific analysis done when the program is actually running. Thins kind of analysis, being done at runtime, can detect specific behaviors, like accessing deallocated memory, leaking memory, time spent in functions and so on.
To put it roughly, is static analysis is advanced compilation, dynamic analysis is a particular form of testing that often requires your program to be "instrumented" for it (i.e., modified at the binary level).
In Xcode, dynamic analysis is available through Instruments. You can found more information about it by googling for "xcode instruments tutorial".
In short, you can run your program under dynamic analysis choosing "Running with Performance Tool" and choosing the kind of analysis you want to perform (memory leaks, memory allocation, performance, Zombies, etc.). Instruments will show you in a graphical environment how memory usage evolves, or how long it takes for specific functions to perform, etc.

What is the difference between a static shape and a dynamic shape?
A static shape has a fixed relationship between all of its vertexes. A dynamic shape can vary the position of at least one of its vertexes in relation to the others.

What is static timing analysis in VLSI- ASIC?
Depending on the design methodologies used, three types of timing analysis methods are commonly used: 1. Manual analysis 2. Static timing analysis 3. Dynamic timing analysis
What are the difference between static degrees of freedom and dynamic degrees of freedom?
Mass and damping are associated with the motion of a dynamic system. Degrees-of-freedom with mass or damping are often called dynamic degrees-of-freedom; degrees-of-freedom with stiffness are called static degrees-of-freedom. It is possible (and often desirable) in models of complex systems to have fewer dynamic degrees-of-freedom than static degrees-of-freedom.
What is the difference between statistics and static?
Statistics refers to a mathematical analysis that deals with the collection and interpretation of data. Static can refer to a type of electricity, a lack of movement, or a crackling sound in a phone line.heck, I just want the definitions!

What is static and dynamic analysis?

Differentiate between static and dynamic systems in linear system analysis?
If a system is static then it will be known as STATIC SYSTEM and if it is not static then its a common sense that it will be a DYNAMIC SYSTEM.
What is the difference between static and dynamic fighting?
Static stays the same and dynamic is always different.
What is Difference between static and dynamic list?

What is static code analysis used for?
The static code analysis is used for the analysis of computer software such as video games and programs like Microsoft Word or Photoshop. The difference between this and Dynamic Analysis is that this is performed without it actually executing/starting the program up.
What is the difference between static pressure and dynamic pressure?
The main difference of static pressure and dynamic pressure is:- static pressure is exerted by fluid at rest but dynamic pressure is pressure exerted by fluid in motion.
What is the Difference between Dynamic pressure and static pressure?
The main difference of static pressure and dynamic pressure is:- static pressure is exerted by fluid at rest but dynamic pressure is pressure exerted by fluid in motion.
What is the general difference between a static IP and a dynamic IP?
The general difference between a static IP and dynamic IP is that a static IP is reserved and does not change. A dynamic IP on the other hand changes each time one logs on.
