Weak current engineer and network administrator are two different jobs. Weak current engineers mainly focus on hardware, which mainly involves the establishment and maintenance of hardware in automatic control. They need to master electronic technology and automatic control principles, and their future employment direction is diversified, such as fire protection, security, building automation, integrated wiring and so on. Network management can be divided into primary and advanced. For example, the network management of ordinary internet cafes, the network management of general scale units are junior network management, and simple training can be competent. However, large-scale network managers need to master more knowledge of software debugging and programming, and must go through professional study, otherwise they will not be competent.
