*This question seems like an opinion based question, but here is my opinion on the matter:
Yes the cell phone is changing our views of what is polite and impolite. It is indeed impolite to talk on your phone while you are ordering a drink at Starbucks, because then you aren't focusing on ordering instead you are focused on your phone call which can interfere with your ordering.
Hope this helps!
Normally you can't. You cannot tell if water has been frozen and then thawed.
Class B would be the correct answer.
Answer:
1. Classes and objects
2. Inheritance
3. Polymorphism
4. Data hiding/ encapsulation
5. Interfaces.
Explanation:
Classes and objects depict the major component of the OOP (object oriented programming). It explains the object like a ball in a soccer game development.
The inheritance is like the subclass of the object. Data hiding is a stage in oop where the codes or data are hidden from another users.
In the polymorphism stage, the object is given the ability to change to a sub-object, while in the interface stage a function or method signature is defined without implementing it.
A proxy server is a server that intercepts user requests from the internal secure network and then processes that request on behalf of the user.
The proxy server can be a computer or application program<span> that gets the requests from clients and seeks resources from other </span>servers. It is a <span>intermediary point between the end user and the backbone network.</span>
