This example will describe you the thin Ethernet network. If you're familiar with computer networks this one will be easy to you, but if not then try to understand the following explanation:
The thin ethernet is a popular type of network. It is used in local places eg.rooms or buildings, where connecting cable can be placed. There are some mathematics calculations for the length of the cable of all the network, and length of cable from computer to computer. These calculation for the deployment diagram are not important.
Computers connect to a network cable via connection devices called T-connectors, or sometimes vampire-taps are used. T-connector has three connecting points. Its form is similar with T-letter and thats why their name cames from. Network cable goes from one end-point to the other end-point of the connector, and the third end-point has a cable going to the computer. |
Because length of the network is limited, ending points of the cable must have a
devices called terminators, which gave infinite resistance to the end of cable. Also one
network segment may join another via a repeater. The repeater is a device which amplifies
the signal to reduce losing of signal. The thin Ethernet is represented on the following
picture:
When we get familiar with the thin Ethernet network concept let's draw the deployment diagram for it. This diagram wil look like:

With this example all of the UML diagrams are shown to you. In this day, only that you have to do, are the exercises. But before make some exercises, A global picture with all of the UML symbols is given to you. See it.
