Free CompTIA A+ Support Course for Beginners

CompTIA A+ Support and Troubleshooting gives you a free beginner-friendly route into practical entry-level IT support. You can start without prior IT experience because the course builds from the devices and systems users rely on every day. You learn computer hardware, CPUs, RAM, storage, power supplies, peripherals, printers, cables, workstation setup, operating systems, file systems, permissions, command-line basics, macOS, Linux, and Windows support tasks.

The course is useful because IT support depends on diagnosing problems clearly. You move from mobile device support and workplace connectivity into IP addressing, DNS, DHCP, firewalls, virtualization, cloud service models, malware, phishing, authentication, password policies, encryption, ticketing, documentation, and professional communication. This foundation helps you prepare for deeper CompTIA A+ study, help desk roles, desktop support, network support, cloud basics, or broader IT career pathways.
