Global information distribution networks:
There are two major technologies in global information distribution network. They are:
1. Fibre optic long-distance network
2.satellites
Fibre optic long-distance network:
The long distance network connectivity is mainly done through guided media cables which are like fibre optic cables. These cables are responsible for carrying large packets of data from long distance within few seconds of time. The data which is passed through these cables is covered with full fledged security and accuracy. These cables provide better quality service for interactive applications. These provide attractive economic advantage for selected routes fulfilling the required communication. Now a days the major long distance carriers are keeping their focus on wireless technologies and are making plans to work with different companies on wireless technology. This technology helps increase of communication with accuracy.
Satellite network:
These have advantages over different networks. They are accessible from any spot on the globe and able to provide broad band digital services, including voice, data and video to many points without the cost of wire installation and other costs. The role of satellite in communication industry has changed the communication environment since from many years giving support to transport of long distance Tele-communication and one-way video broadcasts. In 1980's industry introduced a new class of satellites. These VAST satellites require small ground antennas for point to point network services. Now a days VAST networks are being utilized by large corporation to link hundreds of retail sites.
