A false statement is a statement that is not true. Although the word fallacy is sometimes used as a synonym for false statement, that is not how the word is used in philosophy, mathematics, logic and most formal contexts. A false statement need not be a lie.
Interprocess communication is the mechanism provided by the operating system that allows processes to communicate with each other. This communication could involve a process letting another process know that some event has occurred or the transferring of data from one process to another.

Loaders basically load the various object files in memory and do the following: allocating memory space for prog, adjusting memory locations so that all the loaded object files can run properly in combination.
It is not necessary for a user friendly system to be object oriented, as we have made programs in c++ which are sometimes not user friendly.
User friendly systems are not always easy to develop. While developing such system we must have to consider the system from all kinds of user’s point of view. The ease with which they can use a system. So it is off course not an easy task.

While running DOS on a PC, which command would be used to duplicate the entire diskette?
Nassi-Shneiderman diagrams are only rarely used for formal programming. Their abstraction level is close to structured program code and modifications require the whole diagram to be redrawn, but graphic editors removed that limitation. They clarify algorithms and high-level designs, which make them useful in teaching.
