Technologies that can operate in the 125 kHz to 134 kHz range is the

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.

Yuliya22 [10]

Answer:

The recursion function is as follows:

def raise_to_power(num, power):

if power == 0:

 return 1

elif power == 1:

 return num

else:

 return (num*raise_to_power(num, power-1))

Explanation:

This defines the function

def raise_to_power(num, power):

If power is 0, this returns 1

if power == 0:

 return 1

If power is 1, this returns num

elif power == 1:

 return num

If otherwise, it calculates the power recursively

else:

 return (num*raise_to_power(num, power-1))

Answer:

The correct answer is option (D) Identify the impact on safety of the property

Explanation:

Solution

In every Business Impact Analysis, the first and the most important step is for the CISO is to identify and estimate the impact of the aftereffects on the business and property of an organization that may be occurred from the disaster.

Physical security is very important, but it is not noticed by most organizations. It is important if you do not want anyone to take  away your information or destroy it, in case of natural calamity. the reason could be that, the intruder is  doing it for his personal achievement, financial gain,or seeking revenge or when one is taken unaware and becomes a target. If this security is not maintained properly all the safety measures will not be useful once the attacker gets through by gaining physical access.

Example of property can be software, equipment, facilities, company’s assets.
