Because rent transmission channel subject to high expenses. Connecting the dots: dots, it wasted a lot of communication line data transmission are not being used at all times. Point, which makes it more cost-effective and to send most of the information is often not available, full performance of the wires. A communications link that is worth more than just a communication wire is to use a single wire. Machine or multiple points
Each terminal connected to the line of communication is often the buffer for the catchment stores data as possible before sending out the information to be fully effective. In the case of each terminal to send out data at the same time. The collision information. Cause damage to the data, it is necessary to have a control center to manage controls the direction of flow of information
.Multiple connection points, but point to non ferric (Buffer), which is the temporary storage of data prior to sending the data by storing non-ferric until non-full furnish information will be sent immediately, or when there is a command to send. And what range is empty, it can be sent to others. This connection is suitable for communication with large investors, and is not continuous. But it has several limitations as follows:
.
1. the performance of the machine and the software that is used to communicate information
2. The transmission of information generated by sending and receiving data stations
3. The speed of the data transmission channel use
4. Restrictions issued by the organization that controls the communication of individual countries.
