FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -A protocol, based on RFID, that defines how a network uses close-range radio signals to communicate between two devices or objects equipped with NFC technology. Developed by IEEE, towers can cover a 30-mile radius, and two types are fixed wireless and mobile wireless. What are examples of communication lines?

Detailed explanation-2: -RFID RFID (radio frequency identification) is a standard, specifically a protocol, that defines how a network uses radio signals to communicate with a tag placed in or attached to an object, an animal, or a person.

Detailed explanation-3: -Bluetooth is a network standard, specifically a protocol, that defines how two Bluetooth devices use short-range radio waves to transmit data.

Detailed explanation-4: -Understanding Near-Field Communication (NFC) Near-field communication transmits data through electromagnetic radio fields to enable two devices to communicate with each other. To work, both devices must contain NFC chips, as transactions take place within a very short distance.

Detailed explanation-5: -RFID is a technology that uses radio waves to transfer data from an electronic tag, called an RFID tag or label, through a reader attached to an object for the purpose of identifying and tracking the object. Some RFID tags can be read from several meters away and beyond the line of sight of the reader.
