What is the data network?
What is the data network? A computer network or data network is a digital telecommunications network which allows nodes to share resources. In computer networks, networked computing devices exchange data with each other using a data link. The connections between nodes are established using either cable media or wireless media.
Computer networks come in many forms: Home networks, business networks, and the Internet are three common examples.
Here basic types of network connections exist:
Point-to-point:
In computer networking, Point-to-Point Protocol (PPP) is a data link layer (layer 2) communications protocol used to establish a direct connection between two nodes.
Broadcast/multicast:
Multicast is communication between a single sender and multiple receivers on anetwork.
Multipoint:
A multipoint connection is a communication channel between two or more clients of the network, where all data sent by one client is received by all other clients.
Difference Between Point-to-point and Multipoint Connection:
Main difference between point-to-point and multipoint connection is that in a point-to-point connection the link is only between two devices i.e. a sender and a receiver. On the other hand, in a multipoint connection ,the link is between a sender and multiple receivers.
What is a point to point link?
A point-to-point connection is a dedicated communication link between two systems or processes.
What is the broadcast address of the network?
A broadcast address is a logical address at which all devices connected to a multiple-access communications network are enabled to receive datagrams.
What is the difference between broadcast and multicast?
Multicasting identifies logical groups of computers. A single message can then be sent to the group.Broadcast is a packet that’s sent to all devices on specific network.
What is a Unicast?
Unicast is communication between a single sender and a single receiver over a network.
