Point to Point connection :
* Provide a dedicated link (connection pathway that transfer data from one device to another) between two devices.
* Entire capacity of the link reserved for transmission between the two devices.
Multipoint :
* More than two specified devices share the same link.
* Capacity of the channel is shared either
- Spatially : several devices use the link simultaneously
- Temporally : User takes turns to use the link
Bandwidth
Definition:
The term bandwidth has a number of technical meanings but since the popularization of the Internet, it has generally referred to the volume of information per unit of time that a transmission medium (like an Internet connection) can handle. Here’s a quick analogy: Data is to available bandwidth as water is to the size of the pipe. In other words, as the bandwidth increases, so does the amount of data that can flow through in a given amount of time, just like as the size of the pipe increases, so does the amount of water hat can flow through during a period of time. An Internet connection with a larger bandwidth can move a set amount of data (say, a video file) much faster than an Internet connection with a lower bandwidth. You can test your bandwidth availability for free using tools available at Internet speed test sites.
Temporally :
each device take turns to end/recive data through
the medium,so each device get a time limit to
send/recive data.After the time period the medium
will be reserved by another PC for another time
period.
