C. answer the least challenging questions first
because then you get those out of the way and have more time to focus on the harder questions.
Answer:
True
Explanation:
The hexadecimal numbering is the most used numeric system for international operations in a computer, in our daily life we use the decimal system but for the CPU use the byte or octet as a basic unit of memory, we need more than 10 digits, and the hexadecimal system has 16, in addition, the binary system is hard to understand.
Answer:
A. Hertz ----f amplitude.
Explanation:
The rules of physics confirm that frequency is measured in HERTZ and the amplitude is measured in Decibel. And hence, the correct option here is certainly the first option as it states that the frequency is measured in HERTZ and the amplitude is measured in Decibel. Hence, the first one is the correct choice for this question.
Answer:
Option(d) is the correct answer to the given question .
Explanation:
There are various type of algorithm is used for the purpose of the key scheduling such as AES .in the AES algorithm we used same key for encryption and decryption of text .The main objective of the AES algorithm it is used by Various round of the similar plain text encryption to reinforce the cipher text.
- The Option (a) is wrong because In the key scheduling the creating keys are not being used one after just another in the various communication cycles.
- The Option (b) is wrong because In the key scheduling we do not used the the random key for the encryption process .
- The Option (c) is wrong because we will never arbitrarily subdivided into groups of public and private key.
