Answer:
(a)
Assuming the one-time pad P is used to XOR the message M to get ciphertext C, the following holds:
M ⊕ P = C
P = C ⊕ M
this is a basic property of how XOR works.
(b)
P = M1 ⊕ C1
then M2 = C2 ⊕ P
(c)
The attacker can make assumptions about the message (e.g., presence of certain words and spaces) and then calculate which pad would be needed to get them in the ciphertexts. He then has two ciphertexts that should yield valid content, making it much more easy to guess the pad.

Answer:
The correct answer to the following question will be "RAID 5".
Explanation:
- RAID 5 is an obsolete array of the setup of independent disks that uses parity disk striping. RAID 5 classes have a total of three and no full hard drives (HDDs).
- RAID 5 is considered to be among the most stable RAID systems because the stability data is scattered throughout all drives.
- In a RAID 5 package, the minimum amount of disks is three (two for records, and one for variance). The maximum amount of disks in a RAID 5 system is infinite in principle even though your disk array may have created-in limitations. RAID 5 however only defends against a single failure of the motor.
Therefore, this will be the right answer.
Answer:
AND
The <u>AND </u>operator will cause a record to be selected only if two or more
conditions are satisfied.
Answer:
c. Exponentiation has the highest precedence.
Explanation:
Operator precedence decides how an expression is evaluated. For example, Multiplication has higher precedence than addition, therefore a+b*c will be evaluated as a + (b*c). (expression in bold is evaluated first, then added to a)
Option a is wrong since assignment ( = ) has the lowest precedence, therefore addition and subtraction will be evaluated first.
Option b is wrong since exponentiation is right associative.
Option d is wrong because multiplication can never be unary.
Precedence of basic python operators is listed below (Order Highest to lowest):
1) Exponentiation (**)
2) Multiplication (*) , Division (/), Modulus (%). (Same rank means equal precedence)
3) Addition (+), Subtraction(-)
Answer:
Websites
Explanation:
A web server host websites, individuals or corporate websites, this helps us to show our websites in the World Wide Web, there are several companies offers this service, even we can get a free host, but a corporate website or a social media needs a lot of host recourses, these hosts are expensive than other, we could pay a web host monthly or per year.
