Unit 3.3 - Networking Classifications Flashcards
Peer-To-Peer
Usually found in the home or a small office.
Each station has the same capabilities/responsibilities.
ADV - easier to set up than client server network
DIS - making sure there are no viruses is the responsiblity of each user.
Client Server
A computer that allows you to log on to the network, then you will see one or more network drives available to you. Folders/files stored on a file server on the network.
ADV - Files stored in a central location.
DIS - server is expensive to purchase.
Topologies
It is a technical term that means ‘the shape of something’.
the network uses a star topology” means that the basic layout of the network is in the form of a star configuration.
Bus - Topology
A single cable joins all of the workstations, printer, file server etc. At each end of the bus is a ‘terminator’ - prevents signals bouncing back and forth. (best choice for temporary ntwks).
ADV - Easy to add extra workstations.
DIS - If there’s an issues with central cable, entire network crashes.
Star - Topology
Each workstation is connected by its own cable directly to the server. tend to be used in schools/offices as they’re the most reliable.
ADV - If one connection fails, it doesn’t affect the other workstations.
DIS - Usually need an expert to install the network.
Ring - Topology
All computers are connected to one another in a circle. The data passes from one computer to the next and then all they way round until it reaches its destination.
ADV - Transmission of data is fairly simple as it only travels in one direction.
DIS - If a single machine is off, the network doesn’t work.
Mesh - Topology
All of the nodes/computers/workstations are interconnected with one another. Each node sends its own signals but also relays data from other nodes. It is commonly used in wireless networks.
ADV - Data can be transmitted from different devices simultaneously - can withstand high traffic.
DIS - Overall cost of the network is way too high compared to others.
