This specialty focuses on ensuring that computers, networks, and IT systems run smoothly, securely, and efficiently. It combines three important areas:

Computer Maintenance: Diagnosing, repairing, and upgrading hardware and software to keep systems running at peak performance.
Networking: Setting up, configuring, and managing networks (LAN, WAN, Wi-Fi) so that devices communicate effectively and securely.
Cybersecurity: Protecting systems, data, and networks from threats like viruses, hackers, and unauthorized access.

This field is essential for IT support roles, system administrators, and cybersecurity specialists who keep businesses and organizations safe and connected.
