Program Plan Intro

a.

Hexadecimal numbers:

  • Hexadecimal number system is a number system which consists of 16 digits and it is also known as base 16 number system.
  • It consists of 10 digits from 0 to 9 and 6 letters from A to F.
  • Hexadecimal makes it easy to write large binary numbers into smaller groups.
  • It generally uses four bit binary coding.

Octal numbers:

  • Octal number system is also known as base 8 number system and uses the digits 0 to 7.
  • These are made from binary numerals by grouping consecutive binary digits into three groups starting from the right.
  • Octal numbers also makes it easy to write large binary numbers into smaller groups.

Explanation of Solution

b.

Conversion of hexadecimal number E7 into octal number:

  • Here the given hexadecimal value is E7.
  • First convert the hexadecimal value E7 into its equivalent binary value. Hence the binary equivalent is 11100111.
  • Separate three digits from right to left...

Explanation of Solution

c.

Conversion of hexadecimal number 6E into octal number:

  • Here the given hexadecimal value is 6E.
  • First convert the hexadecimal value 6E into its equivalent binary value. Hence the binary equivalent is 01101110.
  • Separate three digits from right to left...

3. Problem Description: Define the Circle2D class that contains: Two double data fields named x and y that specify the center of the circle with get methods. • A data field radius with a get method. • A no-arg constructor that creates a default circle with (0, 0) for (x, y) and 1 for radius. • A constructor that creates a circle with the specified x, y, and radius. • A method getArea() that returns the area of the circle. • A method getPerimeter() that returns the perimeter of the circle. • • • A method contains(double x, double y) that returns true if the specified point (x, y) is inside this circle. See Figure (a). A method contains(Circle2D circle) that returns true if the specified circle is inside this circle. See Figure (b). A method overlaps (Circle2D circle) that returns true if the specified circle overlaps with this circle. See the figure below. р O со (a) (b) (c)< Figure (a) A point is inside the circle. (b) A circle is inside another circle. (c) A circle overlaps another…
1. Explain in detail with examples each of the following fundamental security design principles: economy of mechanism, fail-safe default, complete mediation, open design, separation of privilege, least privilege, least common mechanism, psychological acceptability, isolation, encapsulation, modularity, layering, and least astonishment.
Security in general means the protection of an asset. In the context of computer and network security, explore and explain what assets must be protected within an online university. What the threats are to the security of these assets, and what countermeasures are available to mitigate and protect the organization from such threats. For each of the assets you identify, assign an impact level (low, moderate, or high) for the loss of confidentiality, availability, and integrity. Justify your answers.
