this basis becomes even more uncertain. Therefore, the most basic condition for safe network operation is to ensure the reliability and effectiveness of the transmission media, and to ensure the high performance of the components connected to the network and the good matching between the components, minimize information loss and provide sufficient transmission capacity to meet application requirements today and tomorrow.

Check and install
After the optical cable is connected and the connector is installed, the continuity check of the optical fiber must be carried out, and all the optical fiber cables must be tested. Therefore, the personnel responsible for testing should have some testing equipment capable of testing the installation quality. Two measurements are re
-232C protocol and TTL Conversion:
The RS-232C protocol uses positive and negative voltage to represent the logical state, which is different from the TTL to express the logical state in high and low levels. Therefore, in order to be able to connect with the computer interface or terminal TTL device, the EIA-RS-232C protocol and TTL circuit must be converted between the power level and the logical relationship, it can also be used as an integrated circuit chip. At present, it is widely used as a

Visit http: // 127.0.0.1: 8080/to check whether the default page of tomcat is displayed. It indicates that the tomcat service is running.

In the discussion about Tomcat, one server represents the entire container. Tomcat provides a default implementation of the server interface that users rarely customize to implement server
Service
The service component is an intermediate component embedded within the server, connecting one or more connector to the engine. The service element is well-defined by the user, since the default implementation is simple and sufficient.
