Computers often chain logic gates together, by taking the output from one gate and using it as the input to another gate. We call that a logic circuit. Circuits enables computers to do more complex operations than they could accomplish with just a single gate. The smallest circuit is a chain of 2 logic gates.

Logic circuits include such devices as multiplexers, registers, arithmetic logic units (ALUs), and computer memory, all the way up through complete microprocessors, which may contain more than 100 million gates. In modern practice, most gates are made from MOSFETs (metal–oxide–semiconductor field-effect transistors).

The final step in the object-oriented design (OOD) process consists of developing the package diagrams.

In the field of Computer studies, object-oriented design (OOD) can be described as a design method in which a proper system of interacting objects is planned for making a computing system or software.

The final step of an object-oriented design (OOD) involves the development of package diagrams. Package diagrams are structures or diagrams that are used for representing the model elements. The model elements are shown as packages in this kind of diagram.

Package diagrams are the final step of an object-oriented design process because they help to provide a visual idea of the overall proposed design.

Under which of the following conditions will evaluating this boolean expression

zzz [600]

1.)
((i <= n) && (a[i] == 0)) || (((i >= n) && (a[i-1] == 0))) 

The expression will be true IF the first part is true, or if the first part is false and the second part is true. This is because || uses "short circuit" evaluation. If the first term is true, then the second term is *never even evaluated*. 

For || the expression is true if *either* part is true, and for && the expression is true only if *both* parts are true. 

a.) (i <= n) || (i >= n) 

This means that either, or both, of these terms is true. This isn't sufficient to make the original term true. 

b.) (a[i] == 0) && (a[i-1] == 0) 

This means that both of these terms are true. We substitute. 

((i <= n) && true) || (((i >= n) && true)) 

Remember that && is true only if both parts are true. So if you have x && true, then the truth depends entirely on x. Thus x && true is the same as just x. The above predicate reduces to: 

(i <= n) || (i >= n) 

This is clearly always true.

Question 4 Multiple Choice Worth 5 points)

Morgarella [4.7K]

The correct answer is Boolean logic.

Booleans are true or false statements.

An example of a while loop is:

while 1 < 5:

#do something.

The Boolean statement is 1 < 5 which evaluates to true because 1 is less than 5.

I hope this helps!
