Essential Competencies

Local Area Network Manager (GS-334):

A person with specialized technical knowledge and skills in the operation of local area networks. Duties include advising on, installing, maintaining, and troubleshooting the hardware, software, and infrastructure needed to connect computers together to allow sharing of data, electronic messages, printers, and other resources.
