3.2. Runtime Architecture
As mentioned earlier, both Java and C# differ from traditional languages such as C, C++, and Visual Basic because the code generated by Java and C# runs in a controlled execution environment. This execution environment provides infrastructure services such as memory management, security checks, and type validation to the compiled or interpreted code. Table 3.1 compares the runtime environments of Java and .NET.
Although the CLR and JVM look deceptively similar in their roles, you should note some key differences.
