JIT is the just in time compiler,it is quite different with
other compilers.It compiles the source code just in
time,and it does not compiles hole code ,only the code is
to be executed is compiled.there are three tipes of JIT.
pre jit,econo jit,normal jit.

Answer / guest

Before Microsoft intermediate language (MSIL) can be
executed, it must be converted by a .NET Framework
just-in-time (JIT) compiler to native code, which is
CPU-specific code that runs on the same computer
architecture as the JIT compiler.
Rather than using time and memory to convert all the MSIL in
a portable executable (PE) file to native code, it converts
the MSIL as it is needed during execution and stores the
resulting native code so that it is accessible for
subsequent calls.
The runtime supplies another mode of compilation called
install-time code generation. The install-time code
generation mode converts MSIL to native code just as the
regular JIT compiler does, but it converts larger units of
code at a time, storing the resulting native code for use
when the assembly is subsequently loaded and executed.
As part of compiling MSIL to native code, code must pass a
verification process unless an administrator has established
a security policy that allows code to bypass verification.
Verification examines MSIL and metadata to find out whether
the code can be determined to be type safe, which means that
it is known to access only the memory locations it is
authorized to access.

When compiling the source code to managed code, the
compiler translates the source into Microsoft intermediate
language

(MSIL). This is a CPU-independent set of instructions that
can efficiently be converted to native code. Microsoft

intermediate language (MSIL) is a translation used as the
output of a number of compilers. It is the input to a just-
in-time

(JIT) compiler. The Common Language Runtime includes a JIT
compiler for the conversion of MSIL to native code.

Before Microsoft Intermediate Language (MSIL) can be
executed it, must be converted by the .NET Framework just-
in-time (JIT)

compiler to native code. This is CPU-specific code that
runs on the same computer architecture as the JIT compiler.
Rather

than using time and memory to convert all of the MSIL in a
portable executable (PE) file to native code. It converts
the MSIL

as needed whilst executing, then caches the resulting
native code so its accessible for any subsequent calls


JIT
----

The Just-In-Time (JIT or JITter) compiler, converts the MSIL
(Microsoft Intermediate Language) code into the native code
(CPU

Specific code).

The .NET runtime/Common Language Runtime (CLR) ships three
different classes of JITters.

<li><b>Econo-JIT</b>: This compiler converts the MSIL code
into native code without any optimizations.

<li><b>Standard-JIT</b>: This compiler takes the MSIL code
and optimizes it. So this compiler requires lot of
resources like,

time to compile, larger memory footprint, etc.

<li><b>PreJIT</b>: This is based on the Main JIT and it
works like the traditional compilers rather than Just-In-
Time

compilers. This compiler is used at the time of
installation.

JIT does not compiles hole code ,only the code is to be
executed is compiled

Microsoft intermediate language (MSIL) can be executed, it
must be converted by a .NET Framework just-in-time (JIT)
compiler to native code.

Answer / anil

JIT compiler (Just In Time Compiler) is the main part in the
CLR, which converts the MSIL code into the native code. It
compiles the program quickly in an efficient manner.

What are different types of JIT?

Ans-
JIT compiler is a part of the runtime execution environment.
In Microsoft .NET there are three types of JIT compilers.
Pre-JIT : Pre-JIT compiles complete source code into native
code in a single compilation cycle. This is done at the time
of deployment .

Answer / prashant yadav

jit is a just in time compiler,it converts msil code into
native code..it is different other compilers bcoz it compile
source code just in time and does not compile hole code at a
time...

Answer / girish

jit is just in time compiler...
it work during the CLR execution...
jit will not execute all the code it will compile partial code means which code to be executed at tat time

Answer / vinod kumar kushawaha

JIT compiler is a part of the runtime execution environment.
In Microsoft .NET there are three types of JIT compilers.

Pre-JIT : Pre-JIT compiles complete source code into native
code in a single compilation cycle. This is done at the time
of deployment of the application.

Econo-JIT : Econo-JIT compiles only those methods that are
called at runtime. However, these compiled methods are
removed when they are not required.

Normal-JIT : Normal-JIT compiles only those methods thar are
called at runti
