Write short on the following: Optical Communication, Satellite Communication Cellular Communication Highlight five advantages digital communication has over analog communication. Describe the major components of an optical communication link Describe the architecture of a satellite communication system. Describe the communication systems commonly used in marine operations. Explain the importance of satellite communication and radio communication. Define Voice over Internet Protocol (VoIP). Compare the H.323 and Session Initiation Protocol (SIP) signaling protocols used in VoIP systems. Explain how optical fiber communication has transformed global internet connectivity compared to satellite communication.

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:

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)
