The analysis of the connecting methods of the broad net

From the practical point of view the most practical and economic connecting methods so far have teen ISDN and ADSL for family and some of the small enterprises. The previous one overcomes the shortcoming of slowness of Modem and is not expensive. While the latter will gradually become the main trend as a comparatively advanced method. Although the cable Modem can not be used in a large scale because of its expenditure, its prospects are bright especially for the method of the fibre transportation. STB, which is literally designed only for the users that plan to be on line through the TV set, will meet its better substitute.
