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 high

"Speed test" can be explained in many ways, in the Internet people's point of view is mainly concerned with the Internet access to network resources. To this end, there are a number of websites that also provide test scripts and services that test the speed of access from visitors to the site. This test method is very simple, but due to many factors, test results are generally only as a specific application to access this particular site (such as: HTT
