Network connection model (network topology)<br><br>1. A Star network connection<br><br>It consists of several computers to connect in a star style, namely, one computer that is central to connect to other computers and devices that are left by the central machine will serve to control both communication routing or device administration to be shared. In other words, any computer will be communicating with the computer on your computer, or to any computers you want to print, it needs to be contacted with the printer via the intermediary computer. If the central computer is damaged, the system cannot communicate with each other.<br><br> <br>Picture of a star network connection<br><br>2. Bus network connection<br><br>It connects all the computers and devices on a single communication line, such as double-wire, spiral, coaxial cable, or fiber optic cables that are exported from any device or computer. According to the broadcast feature, it is exported to both directions to all parts of the network system, with software installed on each device as a communication controller. This is a work that doesn't have any devices acting as the system controller. In this case, if any device has stopped working, it will not affect the device that is still running, however, at the moment the system has only one device that can transmit the signal. The other device you want to transmit is to stop waiting until the system has no signal to start sending their signals. If two or more devices transmit the signal at once, the signal issue occurs. (Collision), which will damage the signal of all parties, can not be used. This system is low performance in cases where there are many ka connected.<br><br> <br>Bus network connection image<br><br><br>3. Dial-up network connection<br><br>It's a ring-like connection. Traffic is in one direction using a Token, which permits any computer to have the right to transmit data so that it does not cause data collisions. If any computer wants to send the data, it will go to the Token and enter it with the Token, while the Token is busy. Another computer cannot transmit the data, so it is necessary to wait for an empty Token, which the Token will be empty only when the data is submitted correctly.<br><br> <br>Picture of a star network connection<br><br>4. Integrated network (Mesh Network)<br><br>It's a network that doesn't have a certain shape, it's a multi-network combination, such as a circular, multi-ring, mixed-style network.<br><br> <br>Mixed network connection image
