To become a network administrator you should know about computer and software.
As a network administrator, your tasks generally fall into the following areas:
1)Designing and planning the network
2)Setting up the network
3)Maintaining the network
4)Expanding the network
Each task area corresponds to a phase in the continuing life cycle of a network. You might be responsible for all the phases, or you might ultimately specialize in a particular area, for example, network maintenance.
