Network System

Introduction

      

        A distribution system where multiple power sources are connected to each user to guarantee uninterrupted power. A network system is expensive, so it is used only when constant power is vital. It is essential to learn the basics of networking. Since late 1950s, health institutions in US use mainframes that are connected to terminals in financial offices. A network can range in size from a palmtop connected to a desktop using wireless or cable communication, to a worldwide multi user environment known as the internet.

Network Topology 

       Computers in a network are physically set up using various arrangements topologies.

1. Bus Topology

• a network setup where each of the computers and network devices are connected to a single cable to prevent backbone.

2. Star Topology

• a very common network setup where each oh the devices and computers on a network connect to central hub.

3. Tree Topology

• a very common network setup that is similar to a bus topology and star topology. It connects multiple star network to other star networks.

4. Mesh Topology

• a network setup where each of  the computers and network devices are interconnected with one another in all possible or partial combinations, allowing for most transmissions to be disturbed, even if one of the connections go down.

5. Ring Topology

• configuration where network computer and devices are connected to each other forming a large circle(or similar shape).
