The section called Breaking Substitution Ciphers (p. 166) describes a "random substitution cipher," in which each letter of the

Answer: Compared to a Caesar shift, the random substitution cipher offers many more possibilities, because the encryption is randomly chosen.

Explanation:

A Caesar Cipher is also a type of substitution cipher, but instead of doing it randomly, it shifts the alphabet by a certain number of characters. Therefore, the answer to decrypt the message is simply to figure out that number.

RSB [31]

Answer:

In general the number of  bit registers in Intel 80x86 CPU design when combined together forms a 16 - bit register

An example of the  -bit registers are AH, AL, BH, BL, CH, CL, DH, and DL

Explanation:

Solution

The 8086 CPU design has a total of eight 8-bit registers and these register can be integrated together to make 16- bit register as well.

The 16-bit data is stored by breaking the data into a low-order byte and high order byte.

The name of the 8 bit registers is shown below:

In a flow chart, both the decision structure and the repetition structure use the diamond symbol to represent the condition that
leonid [27]

Answer:

Option A(True) is the correct answer for the above question.

Explanation:

  • The flowchart is used to give the solution of a problem through the diagram in a step by step processor. It helps the user to understand the solution easily. For diagram, it uses many types of symbols that are fixed for every sequence just like An oval symbol represents the start and end of the flowchart which is fixed for every flowchart.
  • So for the decisions in a flowchart, the diamond symbol is used which is to make the decisions and it has two sides-- one is true and the other is false.
  • The decisions are used also to represent the loop structure which is also called the repetition structure because the loop is controlled by the help of decisions so the diamond box is also used for the loop
  • The above question-statement says that the decisions-controlled is used for the loop and for the decisions which are true because it is also described above.
