系统管理员主要负责系统设备,如主机、工作站、打印机和存储设备等;还负责软件的维护,包括系统软件和应用软件,要保证它们安全可靠地运行。但是,系统不是独立工作的,它们通过网络互连起来,并且需要与Internet或其他系统进行远程连接。由于各种原因,网络出现故障在所难免,这时,系统管理员必须能够解决一些简单的网络管理问题,而不应该完全依赖网络管理员。在系统规模不大的情况下,系统管理员也应该承当网络管理员的职责。
The system administrator is mainly responsible for the system equipment, such as mainframe, workstations, printers and storage devices; also responsible for software maintenance, including system software and application software, to ensure that they run safely and reliably. However, the systems do not work independently, they are interconnected via a network, and require remote connections to the Internet or other systems. For a variety of reasons, network failures are inevitable, and system administrators must be able to solve some simple network management issues rather than relying entirely on network administrators. In the case of small systems, system administrators should also assume the role of network administrator.
