An internet connection provides devices access to the global web network, making it essential for browsing, downloading, streaming, and communication. Common types are dial-up (slow and rarely used), DSL (via phone lines), cable internet (using TV infrastructure), fiber-optic (ultra-fast), satellite (for rural areas), Wi-Fi (wireless, using routers), and mobile broadband (via 4G/5G). Each serves different user requirements, offering varied speeds and coverage.
