Radio ________ Identification Systems use radio waves to read and capture information stored on a tag, which can be read from several metres away. The ________ is made up of a(n) ________ to store and process data, and a(n) ________ to receive and transmit data.
A. tag
B. frequency
C. antenna
D. microchip
Choose the correct answer from the options given below:
Understanding Radio Frequency Identification (RFID) Systems
Radio Frequency Identification (RFID) is a technology that uses radio waves to automatically identify and track tags attached to objects. These systems are essential for various applications, including inventory management, supply chain tracking, and security systems. They enable quick data capture without direct line-of-sight interaction.
Identifying the Correct Words for RFID Systems
The question requires us to fill in the blanks in a paragraph about RFID technology. We need to select the appropriate words from the given options (A: tag, B: frequency, C: antenna, D: microchip) to complete the description accurately.
Let's break down the paragraph and identify the correct words:
- The first sentence states: "Radio ________ Identification Systems use radio waves..." The standard terminology for this technology is Radio Frequency Identification. Therefore, the first blank should be filled with 'Frequency' (Option B).
- The second sentence describes the components: "The ________ is made up of a(n) ________ to store and process data, and a(n) ________ to receive and transmit data." This sentence describes the basic structure of an RFID tag.
- An RFID tag typically comprises a microchip (which stores and processes the data) and an antenna (which transmits and receives the radio signals).
- Thus, the second sentence should read: "The tag is made up of a(n) microchip to store and process data, and a(n) antenna to receive and transmit data." This corresponds to Options A, D, and C, respectively.
Determining the Correct Sequence
Based on this analysis, the sequence of words required to correctly fill the blanks is:
- First blank: Frequency (Option B)
- Second blank: Tag (Option A)
- Third blank: Microchip (Option D)
- Fourth blank: Antenna (Option C)
The correct sequence is B, A, D, C.
Matching the Sequence to the Provided Options
We now compare our derived sequence (B, A, D, C) with the given multiple-choice options:
| Option Number | Sequence |
| 1 | B, D, A, C |
| 2 | C, A, D, B |
| 3 | B, A, D, C |
| 4 | A, C, B, D |
The sequence B, A, D, C matches Option 3.
