Q:

What is a stub network?

A) A network with only one entry and no exit point. B) A network that has only one entry and exit point.
C) A network with more than one exit point. D) A network with more than one exit and entry point.
 
Answer & Explanation Answer: B) A network that has only one entry and exit point.

Explanation:

A stub network has only one default path to non-local hosts and no outside network knowledge. Non-local stub network traffic uses a single logical path when traveling in and out of the network.

 

Stub networks are essentially local area networks (LAN) that either do not connect to the outside and relay data packets internally or are dead-end LANs that know of only one network exit. Stub networks may have multiple connections but use one path to single points of destination.

 

Hence, a stub network is a network that has only one entry and exit point.

Q:

What is autoboxing and unboxing ?

Answer

Autoboxing is the automatic conversion that the Java compiler makes between the primitive types and their corresponding object wrapper classes. For example, converting an int to an Integer, a double to a Double, and so on. If the conversion goes the other way, this is called unboxing.

Q:

What is synchronization and why is it important ?

Answer

With respect to multithreading, synchronization is the capability to control the access of multiple threads to shared resources. Without synchronization, it is possible for one thread to modify a shared object while another thread is in the process of using or updating that object's value. This often leads to significant errors.
