CompTIA A+ Certification
Building competence in IT systems takes more than basic technical knowledge. CompTIA A+ combines hardware diagnostics, networking, security, and troubleshooting into a structured, practice-oriented certification – globally recognized as the entry point into IT support.
Key topics
- Analyzing, installing, and commissioning PC hardware
- Setting up, maintaining, and updating operating systems
- Configuring network components and securing connections
- Identifying security threats and implementing protective measures
- Integrating mobile devices and cloud services into IT environments
- Applying service processes systematically and resolving issues methodically
Prerequisites
A basic understanding of IT systems and initial experience working with computers is sufficient.
Target group
The focus is on IT beginners and professionals from other fields looking to move into IT support – for example from helpdesk, service, or technical assistant roles.
CompTIA A+ creates more than a certification – it builds the foundation for a stable IT career with clear development paths toward system administration, networking, or IT security.
