2. Star Network topology

By
In star topology all devices or computers are connected to one centralized server. They are connected with server by hub.
 Star topology is used in that network where end points are directly reachable from central location. Because each nodes link to the server by different cables. There is no risk of data collisions. Each computer connected to the hub by its own cable segments only a single computer can transmit at a time and every computer on the network wait for message. Thus it is best on broadcasting architecture.
a.     Advantages
i.                    Devices are attached to server by its own cable, thus break down of cable affects only to that nodes.
ii.                  Failure of single node will not affect the rest of the network.
iii.                Central hub can be represent with other having more ports to plugs the nodes.
b.     Disadvantages
i.                    Failure of central hub will affect whole network.
ii.                  More expensive.

iii.                Required more cables and costly hub.

What is Java Applets?

By
An applet is a special kind of Java program that is designed to be transmitted over the Internet and automatically executed by a Java-compatible web browser. Furthermore, an applet is downloaded on demand, without further interaction with the user. If the user clicks a link that contains an applet, the applet will be automatically downloaded and run in the browser. Applets are intended to be small programs. They are typically used to display data provided by the server, handle user input, or provide simple functions, such as a loan calculator, that execute locally, rather than on the server. In essence, the applet allows some functionality to be moved from the server to the client.
