1.4 - THE INTERNET & types of internet connections Flashcards
internet definition
a network of interconnected networks which is worldwide/spanning the world
the devices are connected to the internet using the internet protocol suite - TCP/IP
network definition
group of devices that can communicate with each other
keywords to describe the characteristics of internet connection
- range
- latency
- strength
- bandwidth
- contention
latency
how long it takes to get the message
range
how far away you can still use the internet reliably.
bigger range - you’re far away but you’re still able to use the network.
strength
how consistent the network is
low strength - not good.
bandwidth
how much data can be transferred
high bandwidth - faster data transmission
contention
how many users can use the network at once and how well it performs
uncontended - one user
list the type of internet connections
copper cable
optical fibre
satellite
microwave
mobile data network
which internet connetions are wired?
optical fibre
copper cable
copper characteristics
cheap
high latency
common network table
optical fibre characteristics
it uses light not electricity which allows it to have a fast connection
it has a high bandwidth (faster data transmission)
low latency
they can break and snap
expensive
mobile data network
connected to the internet through cellular
example: 4G/5G
it has strength that varies depending on the location.
5G characteristics - mobile data network
- low latency
- high bandwidth than 4G
- lower range than 4G - (it cannot spread that far, it needs to be close to the reciever)
wifi characteristics
greater ranger, bandwidth than bluetooth
bluetooth and wifi have contetntion issues (slow performance), if you’re in a busy flat/home.
