Introduction to Line Configuration

Two or more devices connected through a link is a network. A link is a transmission path through which data is transfer between two or more device. A device can be a computer, printer, or any other device capable of sending or receiving data from the other node/device through the network.

Types of Line Configurations

  1. Point to Point connection
  2. Multipoint connection

Point to Point connection

1. It is a dedicated communication link between two devices.
2. It is simple to set up, understand and maintain.
3.  It is connected through cable or wire but satellite or microwave link is also possible.

Example

  1. Communication between Television and remote control for changing the channels through infrared ray.
  2. A computer connected by a telephone line.

Multipoint connection

  1. In this connection, more than two computers are connected through a single link.
  2. It is also called a multidrop configuration.

Example

ATM is an example of Multipoint connection

Two types of Multipoint Connections

  1. Spatial Sharing: If several computers can share the link simultaneously, its called Spatially shared line configuration.
  2. Temporal (Time) Sharing: If users must take turns, it is a timeshared connection.
