1) Full form of MSIL and JIT

MSIL — Microsoft Intermediate Language

MSIL is the intermediate language generated when C# or VB.NET code is compiled. It is CPU-independent code that the CLR (Common Language Runtime) converts to native machine code.

C# Code (.cs) → Compiler → MSIL (.dll/.exe) → JIT Compiler → Native Machine Code

JIT — Just-In-Time Compiler

JIT compiler converts MSIL code to native machine code at runtime, just before execution. This is why .NET applications are platform-independent — MSIL runs on any platform with a JIT compiler.
