Network Administrators keep a companys technology system running smoothly. They make sure computers and other devices are operating correctly so that employees can do their jobs. Because business operations in the 21st century are so dependent on technology, Network Administrators (sometimes called Systems Administrators) must act quickly when problems arise. Sometimes this leads to overtime or being called in over the weekend to troubleshoot. Part of a Network Administrators job may also be to examine the organizations services and goals in order to plan for future technological purchases and needs.
