WIRED TOPOLOGIES Flashcards
1
Q
TOPOLOGIES is
A
the layout of how a computer communicates with other devices
wired or wireless
2
Q
STAR topology is
A
- all computers connected to a central wiring point e.g. a Hub or Switch
- all data on a Star Network pass-through this Hub before travelling to its destination point
3
Q
RING topology is
A
- computers connected in the shape of a closed-loop
- every computer on the loop has two neighbours for communication purposes
- data is sent around the loop until it reaches its final destination
4
Q
BUS topology is
A
- all the computers\devices are connected to a single cable or backbone
- connection is via coaxial cable using T-Connectors\BNC
5
Q
MESH topology is
A
- each computer on a network is connected to every other computer on the network
- it handles failure very well with so many connections on the network
6
Q
star BENEFITS/DISADVANTAGES
A
- if one computer fails the network isn’t impacted
- each computer has their own cable connection
- a single point of failure
- if the central hub fails then all the computers go down
- requires more cable so expensive
7
Q
ring BENEFITS/DISADVANTAGES
A
- easy to install
- easy to troubleshoot
- all nodes have an equal chance of transmitting data
- it’s old and rarely used today
- a single break in connectivity is disruptive
8
Q
bus BENEFITS/DISADVANTAGES
A
- cheap and easy to implement
- old and rarely used today
- requires cable to be terminated at both ends using Terminators
- if a computer is removed or the Terminators are loose or missing then the cable would be open and the data would bounce back
9
Q
mesh BENEFITS/DISADVANTAGES
A
- all the connections create a high redundancy level
- if a connection fails the computers can still communicate with each other
- mainly used on WAN [Wide Area Networks]
- extensive cabling requirements make this expensive
- rarely used on LAN[Local Area Networks]
