Internet connections provide access to the web for tasks like streaming, gaming, and communication. They include dial-up (slow and outdated), DSL (uses phone lines), cable internet (via coaxial TV cables), fiber-optic (fastest available), satellite (ideal for remote locations), Wi-Fi (wireless connection), and mobile broadband (via 4G/5G cellular networks). Fiber-optic is best for high-speed internet, while satellite serves areas with limited options.
