new module and the old module have the same functions and interfaces, even if they use different algorithms and protocols. To transmit information and data correctly between computers and terminals in the network, there must be an agreement or rule on the order of data transmission, data format and content, such an agreement or rule is called an agreement. The network protocol consists of three parts: 1. S

We can use the network protocol analyzer to observe the network protocol analysis. Here we will explain the network analyzer. The best way to analyze data packets transmitted over the network depends largely on the device you have. in the early stages of network technology development using the Internet era of HUB or HUB), the answer is very simple. You only need
