factors affecting network performace Flashcards
(20 cards)
measured in bits per second - bit rate
bandwidth
network has a limit on how much data can be moved across in a given time
bandwidth
they have a length limit because the signal gets weaker and weaker the more it travels
bandwith
higher the bandwidth, the more expensive the network becomes to put togther
bandwith
bandwidth is not shared equally amongst users
number of users
the more bandwidth each person uses, the less is available for everyone else
number of users
ethernet cable carries out data
transmission media
they have a length limit because the signal gets weaker the weaker the more it travels
transmission media
fibre optic cables transfer data using light
transmission media
it is expensive compared to standard ethernet copper cable
transmission media
copper cables are used force local connections
transmission media
fibre optic cables are used to handle the heaviest traffic between 2 LANS
transmission media
the further away the users is from the WI-FI, the weaker the signal becomes
wifi performace
wifi signals may be blocked by thick walls and floors, so in some places in the building, you won’t be able to connect
wifi performance
an error happens when a binary 1 is received as a 0, vice versa
error
2 reasons causing this is: interface & signals is to weak
error
delay
latency
on larger networks such as WAN, latency becomes much more important
latency
every hub, cable and router is adding delay to the connection
latency
the larger the network, then the longer it takes for a bit to travel from one point to another
latency
