Telecommunication involves the transmission of information over long distances to communicate. Historically, visual signals like smoke signals and flag signals were used, as well as audio messages. Modern telecommunication uses electrical devices like telegraphs, telephones, radios, fiber optics, satellites, and the internet to transmit information. The internet is a global system of interconnected computer networks that uses standard protocols to serve billions of users worldwide and provides services of information, communication, and data transfer. Bandwidth affects the amount of frequencies that can be transmitted, with greater bandwidth allowing more frequencies. Communication satellites in space are used for services like television, phones, and internet and are composed of subsystems for communication payloads, propulsion, station keeping, power,
