Key Components of Telecommunication Systems:
Transmitter: Converts information into signals.
Transmission Medium: Carries signals (e.g., fiber optic cables, radio waves).
Receiver: Converts signals back into usable information.
Communication Channels: Pathways used for transmitting data.
Network Infrastructure: Includes routers, switches, cell towers, and satellites.
Types of Telecommunication:
- Wired Communication: Telephone lines, coaxial cables, fiber optics.
- Wireless Communication: Mobile networks, satellite, Wi-Fi, Bluetooth.
- Optical Communication: Uses light (mainly via fiber optics) for high-speed data transmission.
- Radio Communication: Used in TV broadcasting, AM/FM radio, and walkie-talkies.
