Communications management is very important where systems are networked and/or work locations are geographically dispersed. 'Communications' can refer to any system for distributing sound, images or data. In the electoral context it usually refers to any communication sent by cable or transmitted by radio or microwave.
Network administration is especially crucial to the smooth operation of a networked computer system, particularly where data is shared on servers. If the network fails, this can stop an organisation from functioning effectively.
Network administration is a specialised function that should be handled by trained technicians. Consult appropriate network specialists for advice on your particular needs.
