First we'll define some terminology.
|
|
|
|
> Hosts \
|
|
End systems - typically don't bother with routing data through a network
|
|
|
|
> Comm Links \
|
|
Typically the actual systems that connect things together. \
|
|
|
|
## Network edges
|
|
|
|
Can be subdivided clients & servers and sometimes both at the same time. \
|
|
|
|
## Access network: cable network
|
|
|
|
Typically when have to share one line we can change the frequency of the signal as one method to provide a distinguishment between different data which may sometimes come from different sources.
|
|
|
|
### Home Network
|
|
|
|
Starting with the modem. All it does it take some signla and convert it to the proper IEEE data format(citation needed).
|
|
Typically we then pipe that data to a router which then just goes around the house in whatever configuration you may need.
|
|
Typically, especially for small businesses, star topology is common where there is some switch in the middle for traffic to be forwarded from the router/modem setup to the individual nodes on the outside of the star.
