B. RFID

Explanation:

RFID is technology which works on radio frequency and it is used for the auto-identification for the different object.
The RFID system mainly consists of two parts. In this RFID system, this RFID reader continuously sends radio waves of a particular frequency
RFID is the use of radio waves to read and capture information stored on a tag attached to an object, providing a unique identifier for an object.
Active RFID tags have a transmitter and their own power source. Instead, they draw power from the reader, which sends out electromagnetic waves that induce a current in the tag's antenna.
Semi-passive tags use a battery to run the chip's circuitry, but communicate by drawing power from the reader.
Radio frequency identification (RFID) can operate in three frequency bands: 125 kHz to 134 kHz, 13.56 MHz, or 856 MHz to 960 MHz. Bluetooth is 2.4 GHz; NFC is 13.56 MHz; and LTE is between 600 MHz and 6 GHz.

stepladder [879]

Answer and Explanation:

The benefits of an large size memory cell is that you can store a lot bigger numbers (and all information is, eventually, numbers) in one cell, which by and large improves the speed and unwavering quality of information get to.

The inconvenience is that you go through a bigger bit of whatever information stockpiling medium you are utilizing on each expression of information, and accordingly can store less information generally speaking.

The biggest positive integer that could be put away in a framework utilizing sign/size documentation, with 64-piece cells is 263. On the off chance that two such cells were utilized to store numbers, the biggest whole number that could be put away by the framework is 2127.
