I am professional in charge of the maintenance of the computer hardware and software systems that make up a computer network. This includes activities such as the deployment, configuration, maintenance and monitoring of active network equipment.
It is typically a mid to senior level of technical/network staff in an organization and is not typically involved with direct user support. I am concentrating on the overall health of the network, server deployment, security, ensuring network connectivity throughout and company's LAN/WAN infrastructure, and all other technical considerations at the network level of an organizations technical hierarchy. Iam considered Tier 3 support personnel that only work on break/fix issues that could not be resolved at the Tier1 (helpdesk) or Tier 2 (desktop/network technician) levels.
