A network administrator is an information technology expert who is responsible for managing, overseeing, and maintaining an organization’s computer network up-to-date and ensuring it is running smoothly. Any organization or a company that uses multiple computer systems or software platforms needs a network administrator to coordinate and connect different computer systems and monitor the communication systems to ensure the information is flowing properly within the organization.
Administrators focus mainly on the network components in their client’s premises or within their organization. They may, at times, have to design and deploy new networks.
In smaller organizations, network administrators take care of maintaining PCs/laptops, routers, switches, printers, tablets, and smartphones, among others. They monitor the network, update hardware and software, test network for glitches, assess network management software and install and deploy security procedures.
Network administrators need to have sound technical knowledge. They should have ability to work well in a team and must possess good problem-solving skills.
Network administrators must be flexible and be abreast of the latest networking and software programs.
In addition to administering the operation of LAN/WAN-related network services, network administrators have to do the following tasks
Coordinating and implementing network software and hardware upgrades
Troubleshooting and resolving LAN/WAN performance, connectivity and related network problems
Administering LAN/WAN security, antivirus and spam control measures
Providing technical oversight of a multi-site enterprise level WAN, including planning, expansion/implementation, maintenance, and troubleshooting
