Answer:

b. AES

Explanation:

AES is an acronym for Advanced Encryption Standard and it is a cryptographic or symmetric block cipher that is based on a substitution-permutation network (SPN) used for the encryption of sensitive data over the internet or web. AES uses a key length of 128, 192 or 256 bits and a block length of 128 bits to encrypt data on web applications.

It is an encryption standard of the government of the United States of America and is supported by the National Institute of Standards and Technology (NIST).

Hence, AES is used to encrypt web application data and it uses an algorithm developed by Vincent Rijmen and Joan Daemen, known as the Rijndael algorithm.

A*=++a/6+b++ 3 if a=3,b=4

Vinil7 [7]

Answer:

$a=22.5$

Explanation:

Given

$a*=++a/6+b++3$

Required

The result when $a=3$ and $b=4$

Analyzing the given instruction

a*=(++a)/(6)+(b++3)

Single out and solve the expressions in bracket

(++a) = a -- When the ++ operator appears before an operand, it is called pre increment. meaning that the operation will be done before the operand will be incremented.

So: in this case: ++a = a

$b++3 = b + 3$

The operator, as used in that statement is the same as: b + 3.

So:

$a*=(++a)/(6)+(b++3)$

$a*=(a)/(6)+(b+3)$

$a*=(3)/(6)+(4+3)$

$a*=0.5+7$

$a*=7.5$

The above expression is calculated as:

$a=a*7.5$

So:

$a=3*7.5$

$a=22.5$
