The technology that enables high-speed data transfer over short distances is typically based on fiber optics or wireless technologies like Wi-Fi and Bluetooth. Fiber optic cables transmit data as light pulses, allowing for rapid communication over significant distances without signal degradation. In contrast, wireless technologies utilize radio waves to connect devices within a limited range, making them ideal for local networks and mobile communications. Both technologies play a crucial role in modern communication infrastructures, supporting various applications from internet access to local area networks (LANs).
