Troubleshooting Network inteface

A network interface equipment / devices that can optimize the performance of computers in a network. This equipment is likely to foreign ears kompuetr users with less knowledge. For the following it will be discussed some minor cases related to the network interface. HUB / SWITCH This tool does have considerable merit, especially to deal with network issues (more than 2 computers). By using this interface, some computers will be connected to the well. Between switches and hubs have the same function, which connects multiple computers at once in order to interact with each other. The difference between them lies in the way they use labor when receiving an electrical signal. At the HUB, when he receives an electrical signal from one computer to another computer (such as a computer), he will repeat this signal on all ports are connected, but the computer port A. in other words, all the ports will get the electrical signals sent by computer A to B, HUB provides only one path for frame delivery. Thus, if the computer C sends frame to computer D, he had to wait for the completion of the shipping process frame by computer A to computer B first. The workings of the so called two-way or simplex. Half duplex is a communications path capable of data transmission in both directions, but in turn. The simplex is defined as a line of communication that can only perform data transmission in one direction at a time greeting. As for the switch, when it receives electrical signals from computer A, it will only investigate the Ethernet address of computer A only, other ports are not touched while loop signal. Different from the HUB that provides one path, the switch has many routes that can be widely used by the user to send the frame to the other users on simultaneously. For example, the switch 24 ports, it supports a bandwidth of 120 Mbps, so it can do 12 times in a single delivery time frames. Of course, the analogy of each share 10 Mbps transmission. Communication channels used by the switch can be referred to as full duplex, the lines of communication that can perform data transmission in both directions at one time. From the above explanation clearly visible location of the most fundamental differences between the two, namely the ability to split the path for data transmission.
