CompTIA Tech+ covers essential technology concepts and terminology that form the foundation of IT knowledge. Hardware refers to physical components like CPUs (Central Processing Units), RAM (Random Access Memory), storage drives, and motherboards. The CPU serves as the computer's brain, processing instructions and calculations. RAM provides temporary memory for active programs, while storage devices like SSDs (Solid State Drives) and HDDs (Hard Disk Drives) retain data permanently. Software encompasses programs and applications that run on hardware, divided into system software (operating systems like Windows, macOS, Linux) and application software (productivity tools, browsers). Operating systems manage hardware resources and provide user interfaces. Networking terminology includes LAN (Local Area Network) for localized connections and WAN (Wide Area Network) for broader geographic coverage. IP addresses identify devices on networks, while DNS (Domain Name System) translates website names into numerical addresses. Routers direct traffic between networks, and switches connect devices within networks. Cloud computing delivers services over the internet, including IaaS (Infrastructure as a Service), PaaS (Platform as a Service), and SaaS (Software as a Service). Virtualization creates virtual versions of hardware, allowing multiple operating systems to run on single physical machines. Security concepts include encryption (scrambling data for protection), firewalls (network traffic filters), and authentication (verifying user identity). Malware describes malicious software like viruses, ransomware, and trojans. Database terminology covers structured data storage, with SQL (Structured Query Language) used for managing relational databases. Backup strategies ensure data recovery through full, incremental, and differential backup methods. Troubleshooting methodology follows systematic approaches: identify the problem, establish probable cause, test theories, implement solutions, verify functionality, and document findings. Understanding these fundamental concepts prepares IT professionals for supporting technology infrastructure across organizations.CompTIA Tech+ covers essential technology concepts and terminology that form the foundation of IT knowledge.
