Point to point network in computer network.

Point to point protocol ppp is a computer network protocol used to transfer a datagram between two directly connected point to point computers. This protocol is used for a very basic level of connectivity providing data linkage between the computers. The point to point scheme provides separate communication channels for each pair of computers. Point to point topology is the simplest topology that connects two nodes directly together with a common link.

The point to point connections use an actual length of wire or cable to connect the two ends but other options such as satellite links or microwaves are also possible. Topologies may define both physical and logical aspect of the network. It can provide connection authentication transmission encryption and compression. The entire bandwidth of the common link is reserved for transmission between those two nodes.

Point to point topology is widely used in the computer networking and computer architecture. Ppp is used over many types of physical networks including serial cable phone line trunk line cellular telephone. As a general rule although there are many exceptions smaller geographically localized networks tend to use broadcasting whereas larger networks usually are point to point. When more than two computers need to communicate with one another the number of connections grows very quickly as number of computer increases.

Point to point is sometimes abbreviated as p2p. Often multiple routes of different length are possible so routing algorithms play an important role in point to point networks. Both logical and physical topologies could be same or different in a same network. The term is also used in computer networking and computer architecture to refer to a wire or other connection that links only two computers or circuits as opposed to other network topologies such as buses or crossbar switches which can connect many communications devices.

A network topology is the arrangement with which computer systems or network devices are connected to each other. Point to point network topology is a simple topology that displays the network of exactly two hosts computers servers switches or routers connected with a cable.
