Multi programming:It is the technique of running various programs at a time by using timesharing.It permits a computer to do various things at same instant. It creates logical parallelism.The notion of multiprogramming is that the operating system keeps various jobs in memory concurrently. The operating system chooses a job from the job pool and begins executing a job, when such job requires waiting for any I/O operations the CPU is switched to other job. Therefore the main idea is that the central processing unit is never idle.

Cohesion: The level to which a component executes a single well-stated task. A strongly cohesive technique, for example, will execute a single task, like adding an item to a data structure, or sorting several data, while a weakly cohesive technique wi
Discrete simulation: In a discrete simulation, the time passes at an irregular rate which is determined by the primary events of interest in simulation.
Interpreter: A program that executes a translated version of the source program by implementing a virtual machine. The interpreters usually simulate the actions of an idealized Central Processing Unit. An interpreter for Java should implement the Java
Coupling: Coupling occurs whenever classes are aware of each of other as their instances should interact. The linkage between two classes which might be either weak or strong. Stronger coupling occurs whenever one class has a thorough knowledge of the

Default label: The destination for all values employed in a switch statement expression which do not contain explicit case labels. The default label is not obligatory.
Limit the Use of Pre-processor Directives: The C pre-processor is powerful, but unrestricted use of it can lead to code that is hard to understand and analyze. Limit its use to inclusion of header files and simple macro definitions. Avoid features suc
