Full form of CLR is
Common Language Runtime and it forms the heart of the .NET framework.All Languages have
runtime and its the responsibility of the runtime to take care of the code execution of the program.For example
VC++ has MSCRT4 0 .DLL,VB6 has MSVBVM60.DLL , Java has Java Virtual Machine etc. Similarly .NET has CLR.Following are the responsibilities of CLR

√ Garbage Collection :- CLR
automatically manages memory thus eliminating
memory leakes. When objects are
not referred GC automatically releases those
memory thus providing efficient
memory management.
√ Code Access Security :- CAS
grants rights to program depending on the security configuration of the
machine.Example the program has rights to edit or create a new file but the security
configuration of machine does not allow the program to delete a file.CAS will take
care that the code runs under the environment of machines security
configuration.
√ Code Verification :- This
ensures proper code execution and type safety while the code runs.It prevents the
source code to perform illegal operation such as accessing invalid memory
locations etc.
√ IL( Intermediate language
)-to-native translators and optimizer’s :- CLR uses JIT and compiles the IL code to
machine code and then executes. CLR also
determines depending on
platform what is optimized way of running the IL code.
