A computer abuse technique called a logic bomb involves inserting unauthorized code in a program, which, when activated, may cause a disaster, such as shutting the system down or destroying files.

<h3><u>Explanation:</u></h3>

Logic bombs are the set of commands that are embedded in a program and has some undesirable and harmful effects when some of the mentioned conditions are fulfilled. When the condition is satisfied logically, this program will begins get executed thereby affecting the computer system in an undesirable way.

These are considered to be a Malware that begins the tasks that it incorporated in it when the logical conditions are satisfied. It is kind of break that occurs in a system in which it is triggered to be executed and attacks it automatically when certain conditions are met.

Answer:

Creates order and harmony → <em>color</em>

Creates an emotional impact → <em>texture</em>

Brings a feeling of depth to a design →<em> form</em>

Draws or minimizes attention → <em>space</em>

Divides space and redirects the eye → <em>shape</em>

Explanation:

The visual element that creates order and harmony is <em>color</em>

Color can be used to create visible patterns that can be recognized as being in harmony or disagreement

The visual element that creates emotional impact is <em>texture</em>

Texture can be used to convey either the emotions of the object or the artist

The visual element that brings a feeling of depth to a design is<em> form</em>

Form is used to present a 3-D appearance of an art, and therefore, it is used to show depth of a 2-D drawing

The visual element that draws or minimizes attention is <em>space</em>

The arrangement, location, and size of the space occupied by an object can be used to draw or minimize attention

The visual element that divides space and redirects the eye is <em>shape</em>

Shape is used to divide space into areas easily recognizable by the eye

Given a floating-point formal with a k-bit exponent and an n-bit (fraction, write formulas for the exponent E, significant M, th
ANEK [815]

Answer:

A) Describe the number 7.0 bit

The exponential value ( E ) = 2

while the significand value ( M ) = 1.112  ≈ 7/4

fractional value ( F )  = 0.112

And, numeric value of the quantity ( V )  = 7

The exponent bits will be represented  as :  100----01.

while The fraction bits will be represented  as : 1100---0.

<u>B) The largest odd integer that can be represented exactly </u>

The integer will have its exponential value ( E ) = n

hence the significand value ( M )

=  1.11------12 = 2 - 2-n

also the fractional value ( F ) =  

0.11------12 = 1 – 2-n

Also, Value, V = 2n+1 – 1

The exponent bits  will be represented  as follows:  n + 2k-1 – 1.

while The bit representation for the fraction will be as follows: 11---11.

<u>C) The reciprocal of the smallest positive normalized value </u>

The numerical value of the equity ( V ) = 22k-1-2

The exponential value ( E )  = 2k-1 – 2

While the significand value ( M )  = 1

also the fractional value ( F ) = 0

Hence The bit representation of the exponent will be represented as : 11---------101.

while The bit representation of the fraction will be represented as : 00-----00.

E = integer value of exponent

M = significand value

F = fractional value

V = numeric value of quantity
