Public access to the Internet In order for the members of the community to gain the benefits of the Internet, they need to have access to it. This might not be possible in some areas where few people can afford computer equipment. In many of these communities, offering people free or very cheap access to the Internet has solved the problem. Access is obtainable at public places such as shopping centers, libraries, community centers, etc.
This type of access is ideal for people who do not have access to the Internet at home or at work. Cybercafis Cybercafi?? s are coffee shops that also offer computing facilities.

(When it took off, its current speeds, height and position, its expected landing time, etc. ) http://www. flytecomm. com/trackflight. html Taxis If you want to hire a taxi, you usually have to ring a local taxi firm and the radio operator uses the radio to find out which taxi is nearest to you. The closest taxi driver then radios back to confirm that they want the job. The operator then gives the details of the job, including the address. The problems with this system include: 1.
Interference on the radio can sometimes make the instructions unclear 2. Taxis occasionally go to the wrong address or arrive at the wrong time 3. Taxis sometimes get lost and arrive late Many taxi firms now have a new system, which make use of global positioning. This system enable the taxi office to pinpoint a taxi that is free and nearest to the caller. The details of the pick-up are displayed on a small screen on the taxi’s dashboard so the driver no longer has to rely on voice messages.
The system can also provide detailed instructions on how to get to both the pick-up and drop-off points.

Using ICT to find you way: using satellite positioning systems Satellite positioning systems are able to locate the position of any object on the Earth’s surface. Theses systems can be used to locate the position of an aircraft or ship or even a person. Some cars are equipped with a similar system so that the driver can locate their position on a map on a small screen inside the car.
The driver can then use the system to obtain directions to their destination. Some systems give the directions (turn left, turn right, etc.) on a screen whereas others give the driver verbal direction as they approach junctions and turns. Hand-held satellite positioning systems are available and are used by people walking in isolated regions such as mountains or deserts. Satellite positioning systems use information from a host of satellites to determine where the driver is located, and a small computer is used to provide the maps. As well as giving details of roads, the system can also provide information on the locations of airports, banks, hotels, restaurants, etc.
