network administrator is better or system administrator.?

Answer 1

network administrator is better,

b'coz he does the overall work and he can maitain the system also.

Answer 2

The titles are pretty much synonymous most of the time, especially in smaller shops.

In larger organizations, a network administrator generally adds users to the network, resets passwords, sets up groups and security, etc. A systems administrator generally handles firewalls, routers, switches, printers and other infrastructure. Either one may set up and maintain servers.

A lot of it goes down to semantics or even politics. In the place where I work (over 150 folks in the IT department) all of those tasks are performed by folks whose basic job title is Network Analyst.
