Final answer:
The 'protected internal' access modifier in programming languages allows access to a member by any code in the same assembly, or by derived classes in other assemblies.
Step-by-step explanation:
The access modifier in programming languages such as C# that allows a type or member to be accessed by any code in the same assembly, or from within a derived class in another assembly, is called protected internal. The protected internal access modifier is a combination of protected and internal, where protected allows the derived classes to access the members, and internal allows access from any class within the same assembly.
Therefore, a member with the protected internal access modifier will be accessible from any class in the same assembly and also from derived classes located in other assemblies.The access modifier that allows a type or member to be accessed by any code in the assembly in which it is declared, or from within a derived class in another assembly, is internal. In C#, the internal keyword is used to specify this access modifier. It is the default access modifier for members when no access modifier is explicitly specified.
