Explain how optical fiber communication has transformed global internet connectivity compared to satellite communication.

1. A modern telecommunication system is an integrated network of hardware and software components designed to transmit information (such as voice, data, or video) over long distances. It involves the conversion of information into electrical, optical, or radio signals, their transmission through a medium, and their reception and conversion back into usable information at the destination. These systems are crucial for global communication, enabling everything from phone calls to internet access. Here's a block diagram illustrating its major components: Block Diagram of a Modern Telecommunication System Information Source (e.g., Voice, Data, Video) ↓ Transmitter (Encodes and modulates the information into a signal) ↓ Transmission Medium (e.g., Optical fiber, Coaxial cable, Radio waves, Satellite link) (This medium is often affected by Noise and Interference) ↓ Receiver (Demodulates and decodes the signal back into information) ↓ Destination (e.g., Human ear, Computer display, Storage device) What's next? 📸
