If u want to use my windows application into other, we create DLL of it.(similar to packages in java) Best example would be using System. We are using dll named system in our application to use the functions & methods in it. 1. What is GAC ? We use gac to store a common dll between multiple application. Consider u have two adobe application which use same dll, they can store the file there. 2. What is dll hell ? Well, earlier, if u installed new dll, earlier dll life would get override. If u have not implemented any function in the new dll, the program depended on it won't work. So, we know have versioning of dll. So, the software can differenciate between 2 dll files. 3. What is boxing ?! Boxing is to convert the value type (int, float or string) to object. Pros: 1. As it's object, multiple value type can be stored together in collections. 2. Object is a reference type. Plz study difference between value & reference type. How method overloading works ?! Basically if u want to use the same function with multiple multiple parameter. Ex: if u want to add 2 digits. U can create two functions with same name but multiple parameter like add(int,int) // add 2 num add(int,int,int) //add 3 num It will decided on runtime which method should be called. If there are 2 variable passed, it will go for 1st functional only. Hope it helps 😁 This are for ur understanding only. Plz refer to online articles for exact terminology.
