POINT TO POINT & MULTIPOINT NETWORK

PHYSICAL STRUCTURE OF NETWORK

            The physical structure of network means that how the nodes are connected physically and how many nodes are take parts in that network. In term of how many nodes/device are connected in a network the physical structure of network is divided in to two parts that is,

                    1.       Point to Point Network

                    2.       Multipoint network

    Both this technique is used to connect devices in network through a wire in order to communicate, but the difference between this two network physical structure is one is used to connect only two devices that is point-to-point and other is used to connect more than two devices in a network called multipoint network see further explain below.

Point to Point Network

                The simplest form of the physical structure of network and unicast network, in this network only one sender and one receiver connect with each other to communicate data. Such as when transfer data between two mobiles or computer by using Bluetooth and other application like Zapya and Shearit etc.
    We can make Point to Point network by connecting two computers using network wires, here only these two nodes can perform data communication.

point to point network

                This type of network is use in immediate work, in a room or personal use.

Multipoint Network

                Multipoint network also known as broadcast networking, in this type of network the connection configure between more than two devices. However there will be only one communication line on which all nodes are connected and one can be sender and others all will receiver. Like TV broadcasting one station is broadcaster or sender and it has many receivers.

Difference between Point to Point and Multipoint Network

Point to Point	Multipoint
When a single line is used only between two devices, it is point-to-point network.	In multipoint the single line is used to connect more than two devices in a network.
In this network the entire channel capacity is reserved for only these two devices.	Where in multipoint network the capacity of channel is shared temporarily by nodes. Or the capacity of channel Is divided among nodes.
Here only a transmitter and a receiver.	In this network there is single transmitter but multiple receivers.
