    Where should the network engineer go?

    At present, the network administrator is the most important link in our network construction and network operation, including the whole technical construction of network security. so in fact, many people think that the network administrator will be the network administrator in the future and it is wrong to position the network administrator from such a point of view. The network administrator is really in the information construction in a unit.
