Network layers

To reduce their design complexity, most networks are organized as a series of layers,each one built upon below it.How ever In each network we can see this concept and contents of each layer,function of each layer,the name of each layer will be changed one network to another network..But Basic concept is network layer concept..Its like this Layer n on one machine communicate with another machine ,wich is having n layers..the rules and conventions used in this conversation is known as a protocol.

Basically ,A protocal is a set of rules,agreement among communication parties and it says how It should go and proceed..

7 layers.

1. Physical
2. Data link
3. Network
4. Transport
5. Session
6. Presentation
7. Application

Overloading Methods..

Method overloading is the process of creating multiple methods with the same name.How ever,Each of this methods should be unique cuz compiler will be able to tell the difference.!!!
Using signature it can be solved..!!

Ex:-

public double area_of_circle()
public double area_of_circle(double a)
public double area_of_circle(double a,double b)
