Bus+Network

Bus Network Is a network in which all computers are connected to a single wire that has two endpoints. The advantages of it is that it is relatively cheep and easy to make. The disadvantages of a bus net work is that it is slow. As all the data form all the other computer has to go down one cable. Also if that cable brakes there would be no alternative rout for the data to travel so the hole net work would stop running.

Advantages


 * Easy to implement and extend.
 * Easy to install.
 * Well-suited for temporary or small networks not requiring high speeds (quick setup), resulting in faster networks.
 * less expensive than other topologies (But in recent years has become less important due to devices like a switch)
 * Cost effective; only a single cable is used.
 * Easy identification of cable faults.

**Disadvantages **

 * Limited cable length and number of stations.
 * If there is a problem with the cable, the entire network breaks down.
 * Maintenance costs may be higher in the long run.
 * Performance degrades as additional computers are added or on heavy traffic (shared bandwidth).
 * Proper termination is required (loop must be in closed path).
 * Significant Capacitive Load (each bus transaction must be able to stretch to most distant link).
