Scientific and Technical Concepts of Communication:
1. Types of Electromagnetic Radiation: Communication primarily involves the use of electromagnetic radiation. The types of radiation commonly used are radio waves, microwaves, infrared waves, visible light, ultraviolet waves, X-rays, and gamma rays. Each type has a specific frequency range and characteristics suitable for different communication purposes.
2. Transmission of Information: Information is transmitted through various methods, such as modulation and encoding. Modulation involves varying certain properties of the electromagnetic waves, such as amplitude, frequency, or phase, to represent the information being sent. Encoding refers to converting information into a suitable format, such as binary code, before transmitting it. These processes enable the transfer of data, voice, images, and videos through different communication systems.
3. Wired vs. Wireless Communications: Wired communications involve the use of physical cables or wires to transmit signals. Examples include Ethernet cables for internet connections or coaxial cables for cable television. In wired communication, the transmission medium is typically more reliable and provides higher data transfer rates.
On the other hand, wireless communications use electromagnetic waves to transmit signals without the need for physical cables. Examples include Wi-Fi, cellular networks, and satellite communications. Wireless communication offers more mobility and flexibility but can be subject to signal degradation or interference.
