FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -radio technology, transmission and detection of communication signals consisting of electromagnetic waves that travel through the air in a straight line or by reflection from the ionosphere or from a communications satellite.

Detailed explanation-2: -Radio is the technology of using radio waves to carry information, such as sound, by systematically modulating properties of electromagnetic energy waves transmitted through space, such as their amplitude, frequency, phase, or pulse width.

Detailed explanation-3: -Radio Spectrum Radio waves are at the low-frequency portion of the electromagnetic spectrum used primarily for communications signals. Applications such as citizen band, AM and FM radio, radar, and television work depending on their position in the spectrum. Radio waves are separated into parts or bands by frequency.

Detailed explanation-4: -While many different types of EMF are used to convey information over distance, the most common are radio waves, also called radiofrequencies. This is a wide spectrum ranging from tens of kilohertz to 300 gigahertz.

Detailed explanation-5: -antenna A radio antenna is a device used to transmit or receive electromagnetic waves. bluetooth Short-range radio technology making it possible to connect multiple types of wireless device. cell Maps out a geographic area covered by a base station.
