Answer:
In mathematics and digital electronics, a binary number is a number expressed in the base-2 numeral system or binary numeral system, which uses only two symbols: typically "0" (zero) and "1" (one). The base-2 numeral system is a positional notation with a radix of 2. Each digit is referred to as a bit, or binary digit.
Explanation: and the key to reading binary is separating the code into groups of usually 8 digits and knowing that each 1 or 0 represents a 1,2,4,8,16,32,64,128, ect. from the right to the left. the numbers are easy to remember because they start at 1 and then are multiplied by 2 every time.
Answer:
Biometrics in this sense refers to any human information that can be used as unique identifiers such as fingerprints, iris scan, facial scan, voice patterns and typing cadence.
The advantage of biometrics is that they can not be duplicated. That is, two people can never share the same biometric information except if they are clones of each other.
Given that this kind of unique identifiers can be also be stored as data, it thus creates a cyber risk. If stolen, it may be used to access any part of the user's life. The loss of biometric data to hackers is so detrimental that it can be used to falsify legal documents, identifications documents, or other forms of and even credit card details.
