Line Configuration in Computer Networks




The manner in which two devices of communication are connected to a link is called the line configuration. The link is the channel of communication along which data is transmitted between two or more devices. The devices have to be attached to the connection in a similar way and at the same period for the process of communication to be effective.




The link can also vary depending on the distance between the two computer devices. It means that it can either be physical or wireless that relate to the way in which the link is established. There are two types of line configuration in computer networks.


Point to point

It is a line configuration which utilizes the length of the cable in creating a connection between the two computer devices. Other elements of the linkage include microwave and satellite link. It is simple to understand and establish a point to point line configuration the fact that it is one of the widely used network topologies.

 A pair of wires is also applicable during the connection as long as they are appropriate for transmitting information along the established link. An example of a point to point configuration is a telephone line connected to a computer. It can also be a connection between a remote control and television, home theater or a CD player. Reservation is made available to the entire capacity of the channel. Another example of a point to point connection (PPP), is the connection of devices in a mesh topology.


Multipoint Configuration

Multipoint configuration involves a single capacity of a link being shared by several devices. It is also referred to as a Multidrop connection, and the channel capacity can be shared temporarily or spatially. This type of configuration allows packets to be broadcasted across the specific networks. The devices in which the link is established are capable of communicating with each other while sharing the connection.

Spatial and time sharing are the two types of multipoint configurations. The space distribution is a situation where many devices share the links in a contemporary way. Temporal or time sharing involves computer users taking shifts while utilizing the link.




All these types of Multidrop configurations are active, and their performance depends on how the relationship is established. The information is transmitted over the connection to various computer devices sharing the connection. The significant difference between the multipoint and point to point line configurations is the number of devices attached by the link.
