CompTIA

CompTIA (Computing Technology Industry Association) offers a range of certifications that are highly regarded in the IT industry. These certifications cover various technology-related skills and are designed to validate the expertise of IT professionals. As of my last update in January 2022, here are some of the key CompTIA certifications:

CompTIA IT Fundamentals (ITF+): This certification is ideal for individuals who are new to IT. It covers essential IT skills and helps beginners understand the basics of IT, including hardware, software, networking, and security.
CompTIA A+: A+ certification is for entry-level IT technicians. It covers topics related to hardware, operating systems, networking, security, and troubleshooting. A+ is a widely recognized certification for technical support and IT operational roles.
CompTIA Network+: Network+ certification is for professionals who work in IT networking roles. It covers networking concepts, infrastructure, network operations, security, and troubleshooting.
CompTIA Security+: Security+ certification is for IT professionals specializing in cybersecurity. It validates knowledge and skills in areas such as network security, compliance, threats, vulnerabilities, access control, and cryptography.
CompTIA Linux+: Linux+ certification is for IT professionals who work with Linux operating systems. It covers Linux administration, security, and troubleshooting.
CompTIA Cloud+: Cloud+ certification is for IT professionals working in cloud technologies. It covers cloud models, virtualization, infrastructure, security, and resource management.

It's important to note that CompTIA certifications are typically valid for three years.
