Point-to-point Networks

A Point-to-point Network is a communication Network. Existence of several points is recorded in a Point-to-point Network. These points are important locations and are called nodes. Here information is passed from previous point to  next point. We mean from node to node. 

Let us suppose that information is at the first point ( node ) of a Point-to-point Network. The information at the first point has a size. It has to go from first point to second point. To go from the first point to the second, a communication line is needed. This communication line should be free enough to carry the size of information at the first point. 

Now, one more requirement exists. The second point of a Point-to-point Network is the point to receive information from the first point. This        point should have enough memory space. This space should be enough to fit the size of information at the first point. 

If a node in a Point-to-point Network has large storage capacity, it is easy to store enough information for transmission. If a Point-to-point line ( communication line ) emerging from this point is  having limited speed ( and hence less costly) to carry information, it is bearable. It is because the node with enough storage is always ready with information. Because of enough storage the point ( node ) will support transmission for a long time. Information is readily available at the node. It is continually dispatched. So, even if a Point-to-point line is slow ( and less costly ) it will not affect the Network performance very much.

In a Point-to-point Network the nodes ( points ) can have slow/moderate speed processors. Slow/moderate speed processors put information at their speed. So, slow and inexpensive Point-to-point communication lines are suitable. 

It can be concluded that a large size memory at a point ( node ) does fair justice with data transmission.
