Answers
Educational initiatives that utilize radio and television typically have quite high initial start-up/capital costs, but once they are up and running, on-going maintenance and upgrade costs are much lower (making initiatives utilizing radio and TV for distance learning in the education sector particularly appealing for donor support in many cases). One-to-many broadcast technologies like radio and television (as well as satellite distribution of electronic content) are seen as less ‘revolutionary’ ICTs in education, as their usage is seen as reinforcing of traditional instructor-centric learning models, unlike computers, which many see as important tools in fostering more learner-centric instructional models.
There are a diverse number of devices use in communication, the nature of the device to be used depends on the nature of the information to be conveyed, when the information for the public it may be made through the news paper, television and the radios, when it is a personal or confidential talk it may be through th phone or through the emails or the letters..
