networks

1. advantages

   • it is efficient
   • they can use multiple computers
   • limits the amount of updates
   • keeps training cost down

2. disadvantages

   • it cost a lot of money to keep safe
   • if the network ever got hackedd then everyones informatien would be at risk
   • if it geos down no one can go on it

3. networks

4. Topologies

   • Star Topology - Star topology is by far the most common. Within this framework, each node is independently connected to a central hub via a physical cable—thus creating a star-like shape. All data must travel through the central node before it reaches its destination. Because no two adjacent nodes are connected, if one goes down, the others will remain up and running. However, if the central node fails, so will all adjacent nodes within the network.
   • Bus topology—also known as line or backbone—connects all devices via a single cable running in one direction. All data on the network also runs through this cable, following the same direction. Due to the limited amount of equipment needed to construct this layout (a single coaxial or RJ45 cable), bus topology is considered a strong, cost-effective option for many MSPs. As the needs of the network grow, you can add more nodes by joining additional cables. Just keep in mind these topologies can only handle so much bandwidth and if the single cable fails, the entire network will fail in turn.
   • Ring topology, as its name suggests, features all nodes arranged in a ring. Data can travel through the ring in either direction, passing through each node until it reaches its destination. Because only one node on the ring can send data at any given time, the chance of packet collisions is greatly reduced. However, like bus topology, one failed node in a ring layout can take all others down with it. Bandwidth is also limited, bringing scalability into question.
