This will include such duties as installing anti-virus and malware protection software, undertaking regular systems maintenance, and troubleshooting problems. Additional duties can include serving as a digital technology information resource for employees and consulting with company leaders on the possible adoption of new technologies. Aside from this, you might be asked to evaluate and boost network system performance, make needed upgrades and repairs, and add approved users to the network and train them in proper usage.
