The CompTIA Network+ certification is a widely recognized credential that validates the essential knowledge and skills needed to design, configure, manage, and troubleshoot wired and wireless networks. Designed for IT professionals, it covers a range of topics including network technologies, installation and configuration, media and topologies, management, and security.
