  • Set Up Computer Networks (Cable crimping, router/switch configuration, network protocols)

  • Set Up Computer Servers (Domain setup, Active Directory, user policies, server administration)

  • Maintain and Repair Computer Systems and Networks (Troubleshooting, preventive maintenance, virus removal)
