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.
Preventing Crash on Linux
Although known as the linux operating system stable, but crashes can happen anytime.And if a crash would be more difficult to fix. Here are some things to keep in mind that Linux does not crash the system in operation 1. Do not log in as root when not needed. This was done to avoid the mistakes that can damage the system command
With the "plug n play" should be able to detect the hardware windows are added automatically. But in fact not the case. In some cases, the plug N play facility failed to detect the new hardware added to the computer.
Windows is equipped with Plug N Play facility is the ability to automatically detect and configure if no additional card or device into the system. But it was the practice then automatic detection still has many shortcomings. Perankat Windows fails to detect new devices are added is not working.
If that happens, there are two alternatives that can be done. The first alternative is by using the Add / Remove Hardware in Control Panel. Perform the following steps:
1. Click Start => Settings => Control Panel
2. Then in the window that appears, double click Add / Remove Hard ware
3. A wizard will help you to detect hardware. If successful, it will display a message that the hardware found.
If it turns out this way does not work, then chances are your BIOS settings need to be set for Plug n Play feature of Windows can run. To set the BIOS settings, perform the following steps:
1. Perform Restart your PC
2. Press the Del key on the keyboard to bring up the BIOS settings
3. If your BIOS from Award Software, look for part OnO / PCI Configurations and press Enter
4. In the PNP OS option Instelled, change the value of "No" to "Yes".
5. Restart the computer again and re-do the detection of your new hardware.
