Networking Fundamentals

The most elementary of all networks consists of two computers that are connected to each other using some kind of wire or cable to transmit data from one machine to the other. No matter how many computers may be interlinked, or what kinds of connections may be in use.

• Data sharing premises groups of users to exchange information routinely and to route data from one individual to another as workflow demand.

• Because data sharing also premits message, documents, and other files to circulate among users, it can also improve human communication substantially.

• Peripheral device sharing lets groups of users take advantages of peripherals such as printers, scanners, fax machines, and other devices attached directly to a network or to a generally available computer attached to a network.

What is Networking ?

Networking involves connecting computers for the purpose of sharing information and resources.

Starting A Java Program

At first glance, even the simplest java program involves a fair amount of confusing syntax. Consider the following simple program. This program is written on seven lines, and its only task is to print "First Java Program" on the screen.

public class First
{
public static void main(string[]args)

{
system.out.println("First java program")
}
}

The statement that does the actual work in this program is system.out.println("First java program") ;
