Answers

It is often assumed that the delay in store and forward packet switching is negligible. However, this is not always the case, as seen in the example above.

The total delay for the three packets to be processed was 4.05 seconds. This can be attributed to the processing time at the router, as well as any headers that may be added to the packets.

While this may not seem like a significant amount of time, it can add up, especially if there are multiple packets to be processed. In general, store and forward packet switching is a reliable way to route data, but there can be delays involved that should be taken into account.

Declaring a member as protected in the base class provides access to that member in the derived classes but not to anyone else.

Base class and derived classes are concepts of inheritance in the paradigm of Object Oriented Programming. Inheritance is the process in which a new class (called derived class) is created from an existing class (called base class).

When a drive class is created from the base class, it has access to some members of the base class. There are three types of access specifiers to declare members in the base class in order to provide their access in the derived classes.

The first is declaring a member as private. Private members of the base class cannot be accessed by anyone, even not by the derived classes. The second is declaring the base class members as public. Public members can be accessed by anybody including derived classes. The third type is declaring members as protected. Protected members of the base class have accessibility only in derived classes.
