Workings of this tool is to send signals to the entire data packet to the hub ports so that data packets received by all computers connected to the hub unless the sending computer. Sent the signal to be repeated, although the data packet has been received by the destination computer. This causes the function colossion more often when there terjadi.Misalnya delivery of data packets port A to port B and at the same time there is transmission of data packets from port C to port D, there will be collisions (collision) Because it uses the same line (line broadcast the same) so that the data packet will be corrupted causing repeated transmission of data packets. If this happens then Collison which happens to disrupt the activities of sending new data packets or replay. This resulted in a decrease of data transfer speed. Therefore, physically, hub a lamp led which indicates there collision.
When the data packet is sent through one port on hub, Then sending the data packet will be seen and sent to each port other so bandwidth on hub be divided into the port available. More port available at hub, Then bandwidth are available to be smaller for each port.
This makes the data transmission hub with many ports that are connected to the computer slows down.
