Topologies Flashcards
what’s a topology?
The layout of how a network communicates with different devices.
The layout of how a network communicates with different devices is called a _________.
topology
the most common topology is the ____ topology.
star
what’s a star topology?
a network topology where all network components are connected to a central wiring point.
In a star topology, All data on a star network passes through the _______ _____ before continuing to its destination.
central point
Major benefit of star topology?
if one computer 🖥️ failed, or if there was a break in the cable, the other computers would not be affected because each computer has their own cable connection.
Disadvantage of star topology?
if the central hub or switch fails, then all the computers 🖥️ on that central point would be affected. And this is called a single point of failure. If this happens, the entire network goes down.
What’s a bus topology?
network setup where each of the computers and network devices are connected to a single cable or backbone.
Backbone is a ?
Coaxial cable
In bus topology, computers connect to the backbone using special connectors called ___, which are also known as _ ___________.
BNC, T-connectors
Major Benefit of the Bus Topology?
fairly cheap and easy to implement/execute.
Disadvantage of Bus Topology
it requires that the cable be terminated at both ends using terminators.
If a computer is removed or added or if the terminators are loose or missing, then the cable would be open and data would bounce back. This is known as
signal reflection
What’s a ring topology?
network configuration, where each computer is connected to each other in the shape of a closed loop or ring.
in ring topology, every computer on the ring has exactly two neighbors for ____________ purposes.
communication
in ring topology, each data packet is sent around the ring until it reaches ___ ______ ___________.
its final destination
Major benefit of Ring Topology 💍
easy to install and easy to troubleshoot.
Disadvantage of Ring Topology 💍
if just one of these computers goes down, or if there was a single break in the cable, then all data flow would be disrupted.
What’s a mesh topology?
network configuration, where each computer on the network connects to every other computer on the network.
In a mesh topology, by having so many connections, it handles ________ very well.
failure
Mesh topologies are rarely used on _____, because it’s expensive.
LANs
Mesh topologies are mainly used on _____, like the internet.
WANs
the ________ is a perfect example of a mesh topology.
Internet
Major benefit of a Mesh Topology?
it creates a high redundancy level. Because if one or more connections fail, the computers would still be able to communicate with each other
What are hybrid topologies?
a combination of different topologies.
most common forms of hybrid topologies include? (include 2)
star-bus network
star-ring network
what’s a star-bus network?
two or more star topologies are linked together using a single bus connection.
what’s a star-ring network?
two or more star topologies are linked together to form a large ring network.
What’s the simplest form of topology there is?
point-to-point topology
what’s a point-to-point topology?
two hosts that are directly connected to each other using a single cable.
what’s a client-server topology?
A client server topology is where clients connect directly to a centralized dedicated server to access resources rather than connecting to each other.
why do a lot of businesses use the client-server topology?
putting the resources on just one machine, is a lot less work than putting the data on multiple clients. It makes the administration a lot simpler.
what’s a point-to-multipoint topology?
a network architecture that is commonly used in wireless outdoor networks.
What’s a peer-to-peer topology?
A peer to peer topology is where all the clients on the network talk to every other client on the network to share their resources with each other.
In a peer-to-peer topology, there is no centralized server that the clients connect to, they all just connect to ____ _____.
each, other
where would you typically find peer-to-peer topologies? (include 2)
homes and small businesses.
