What is an instruction set?

• The complete collection of instructions that are understood by a CPU


• Machine Code


• Binary


• Usually represented by assembly codes

Elements of an Instruction

• Operation code (Op code)


• Source Operand reference


• Result Operand reference


• Next Instruction Reference

Instruction Cycle State Diagram

Instruction Representation

• In machine code each instruction has a unique bit pattern

Polymorphism in Java

Polymorphism means "any forms." In object-oriented programming, it refers to the capability of objects to react differently to the same method. Polymorphism can be implemented in the Java language in the form of multiple methods having the same name. Java code uses a late-binding technique to support polymorphism; the method to be invoked is decided at runtime.

Overloaded methods are methods that have the same name, but different argument lists. Overriding, on the other hand, occurs when a subclass method has the same name, same return type, and same argument list as the superclass method.

Overloading

As we mentioned, it is mandatory for overloaded methods to have the same names but different argument lists. The arguments may differ

Why Yoga ?

Yoga is a way of life and enables us to have multidimensional approach to life. The human body is not the aim of yoga but is considered means of going beyond physical form of body. Unbalanced state of cause and effect result in ill health. Equilibrium of two is the basic aim of Yoga. A healthy body, therefore may be called as the foundation of Yoga.

Yoga is both an art and science. It can alone save the modern man from personal determination and circumstantial frustration. In other words the practice of 'Yoga' postulates keeping the body healthy and the mind calm and peaceful. Health is our birth-right, and to remain healthy, it is not necessary to depend upon any health centre, physician or medication. It is entirely in our hands to keep healthy. However, in the present-day conditions keeping good health is

Performance of Sorting or Searching

One of the chief concerns in searching and sorting is speed. Often, this concern is misguided, because the sort or search takes negligible time compared to the rest of the program. For most sorting and searching applications, you should use the easiest method available . If you later find that the program is too slow because of the searching or sorting algorithm used, you can substitute another method easily. By starting with a simple method, you haven’t invested much time and effort on code that has to be replaced.

One measure of the speed of a sorting or searching algorithm is the number of operations that must be performed in the best, average,
