1 Repeater
A repeater (repeater) is a network device located on the first layer (physical layer).
As the cables pass through more and more longer, the signal becomes weaker. The purpose of the repeater is to regenerate and re-timer the network signal at the bit level . which allows them to transmit longer distances over the network.
Repeaters only work on a higher-than-premium, without looking at other information
2 hubs (hub)
The purpose of the hub is to regenerate and re-timer the network sig

The improvement of technology is inseparable from practice, and the familiarity of equipment is inseparable from experiments. Cisco's analog devices are already very mature, but h3c and Huawei's simulators are few and there are only two types of Internet available: Routesim (a very simple practitioner); another: The real-machine simulator, the Simeware, The current version of the 5.2a, shown from Ver, is H3C's work, but
Linux is a file-based system, and all hardware, such as software, will have a corresponding file representation under the directory. For Dev This directory, we know the file below it, which represents the Linux device. In Windows systems, devices are well understood, like hard disks, which refer to real hardware. Under Linux for file systems, there are files associated with these devices. Access to them can be put into the actual hardware, think or Linux flexible. It's much easier to do it. You
