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.
External computer components connect to the motherboard through a series of ports on the computer case. Many components have their own dedicated port connections, such as those to connect audio equipment or the computer monitor. Others may share a single type of connector, such as the USB, that connects everything from keyboards and mice to game pads and external hard drives. there
Answer:
Modern browsers use CSS to style all their markup.
How would they render a <table> element if CSS had nothing that could express the appearance of one?
(That, and you might have non-tabular data that you want to render like a table, there are enough people using tables for layout to see a demand for it).
They can be used to format content in a tabular manner when the markup does not use the table element, e.g. because the markup was written by someone who was told not use tables or because the markup is generic XML and not HTML.
You can also design a page using e.g. div elements so that some stylesheet formats them as a table, some other stylesheet lets them be block elements or turns them to inline elements. This may depend e.g. on the device width
Answer:
b. Rubato tremolo
Explanation:
Tremolo is a modulation effect that imposes a rhythmic change in volume of sound. Once discovered in electric amplifier circuits, sound engineers and composers like the Baroque now use this low frequency oscillating modulation technique to create emotional piercing effect on their audience to maintain focus.
The low frequency tremolo can be gotten from the vibrating string in guitars, violins etc, and vocal sound, it is also produced from electronic devices created for its purpose. they are called optical tremolo.
