A device that protects electronic equipment from an increase in power, but not a decrease or outage is a ___.

Basile [38]

Answer: A) Battery backup

Explanation:

A battery backup are used to provide the source of power backup to various hardware components and desktop computers. In many cases, the devices are plugged into UPS ( uninterruptible power supply) for backup power and it is also depend upon the size of the UPS.

All the battery backups are located inside so that is why, the devices are heavy in weight. Usually, the battery backup front required additional button for performing various functions.

And the battery backup devices are manufacture by using the varying degree of backup abilities.

1. Build and test D-type Flip-Flop using a built-in SR flip-flop.

GaryK [48]

Answer:

The attached files contain the realization of a D flip-flop from an RS flip-flop. It also contains the truth tables for both kinds of flip-flops

Explanation:

An SR flip flop is like a light switch. Set turns it 'on' and reset turns it 'off'

A D type flip-flop is a clocked flip-flop which has two stable states. A D type flip-flop operates with a delay in input by one clock cycle.

D type flip-flops are easily constructed from an SR flip-flop by simply connecting an inverter between the S and the R inputs so that the input to the inverter is connected to the S input and the output of the inverter is connected to the R input.

Which of the following is not true about managing your privacy settings? (select all that apply)

Evgesh-ka [11]

I'm going with
The things that you post online become public information.
and
Employers screen job candidates based on social medias.

Because when you post online, you can very easily make your account private, or only share the post to a specified group of people.

Employers also screen job candidates based on their backround, personality, etc.

A contiguous subsequence of a list S is a subsequence made up of consecutive elements of S. For example, if S is 5,15,-30,10,-5,

Sindrei [870]

Answer:

We made use of the dynamic programming method to solve a linear-time algorithm which is given below in the explanation section.

Explanation:

Solution

(1) By making use of the dynamic programming, we can solve the problem in linear time.

Now,

We consider a linear number of sub-problems, each of which can be solved using previously solved sub-problems in constant time, this giving a running time of O(n)

Let G[t] represent the sum of a maximum sum contiguous sub-sequence ending exactly at index t

Thus, given that:

G[t+1] = max{G[t] + A[t+1] ,A[t+1] } (for all 1<=t<= n-1)

Then,

G[0] = A[0].

Using the above recurrence relation, we can compute the sum of the optimal sub sequence for array A, which would just be the maximum over G[i] for 0 <= i<= n-1.

However, we are required to output the starting and ending indices of an optimal sub-sequence, we would use another array V where V[i] would store the starting index for a maximum sum contiguous sub sequence ending at index i.

Now the algorithm would be:

Create arrays G and V each of size n.

G[0] = A[0];

V[0] = 0;

max = G[0];

max_start = 0, max_end = 0;

For i going from 1 to n-1:

// We know that G[i] = max { G[i-1] + A[i], A[i] .

If ( G[i-1] > 0)

G[i] = G[i-1] + A[i];

V[i] = V[i-1];

Else

G[i] = A[i];

V[i] = i;

If ( G[i] > max)

max_start = V[i];

max_end = i;

max = G[i];

EndFor.

Output max_start and max_end.

The above algorithm takes O(n) time .

You've added a clip art image to your slide. Now you want to add a border. Which tab would you use to make this change?

Vinvika [58]

If you want to add a border you have to use 'Insert' tab to make this change. Then you have to click on "Picture" that is placed in the Insert menu, and choose "Clip Art." You can use the search box at the top of the Clip Art gallery in order to find a suitable border. When you finally found it, click on it, then select the button "Insert".
