The following program segment is designed to compute the product of two nonnegative integers X and Y by accumulating the sum of

mote1985 [20]

The program is correct: at the beginning, product = 0. Then, we start summing Y to that variable, and we sum Y exactly X times, because with each iteration we increase Count by 1, and check if Count=X so that we can exit the loop.

You are working with a database table that contains data about music. The table includes columns for track_id, track_name (name

german

The statement that completes the query is: bytes / 1000 AS kilobytes

<h3>SQL (Structured Query Language)</h3>

This is the language that is used to retrieve, update, and store data in the database.

<h3>Columns</h3>

From the question, we have the following table columns

track_id
track_name (name of the music track)
composer
bytes (digital storage size of the music track

To retrieve data from the bytes column, we make use of:

SELECT bytes ......

From the question, we understand that this column should be divided by 1000, and the AS command should be used.

So, the query becomes

SELECT bytes / 1000 AS kilobytes .....

Hence, the statement that completes the query is: bytes / 1000 AS kilobytes

Question 1 :George, a user, is having trouble connecting to network resources, including shared folders on the local network and

vazorg [7]

Complete Question:

George, a user, is having trouble connecting to network resources, including shared folders on the local network and Internet resources. Yesterday he was able to connect with no problems. You need to ensure that he can connect to these resources. Which tool should you use FIRST?

Group of answer choices

A. ipconfig

B. Device Manager

C. My Network Places

D. Control Panel

Answer:

A. ipconfig

Explanation:

As a network administrator, to ensure that George can connect to the network resources, shared folders, and internet resources, the tool you should use first is the "ipconfig" in the command line. This is a troubleshooting process that would help to identify the problem and to establish a theory of probable cause.

<em>Since George could connect the previous day without any problem, it is most likely that the TCP/IP settings has been altered. Therefore, to view this settings you'll have to use an ipconfig command. </em>

Assume that name is a variable of type string that has been assigned a value . write an expression whose value is the first char

4vir4ik [10]

For the first question, you would just add the parenthesis to the string mutation1:

String word = "sadly";

String mutation1 = "(" + word + ")";

For the second you need the method substring from the String class:

It is defined as String.substring(begining, ending);

String name = "Smith";

String firstCharacter = name.substring(0, 1);

0 is considered the beginning of the string, then you get the next 1 characters.

A certain program takes 26.67 seconds to run on 3 processors and 16 s to run on 7 processors. Find the execution time on one pro

brilliants [131]

Answer:

The explanation for the question is listed in the section below on Explanation.

Explanation:

The time needed for a program to execute in 26.67 seconds on 3 processors. Time expected to run the program, therefore, should be as follows:

The time to run on one processor = $\frac{26.67}{3}$ = 8.89 seconds.

The time needed for a program to execute in 26.67 seconds on 7 processors, should be:

Time = $\frac{16}{7}$ = 2.2857 seconds.

Whenever the amount of processors increases the performance or speed should increase.

The time is taken in percentage = $\frac{26.67}{16}$ ×100% = 170 %

As the number of processors increases from 3 to 7, the time required according to each processor increases by 70%.

In one processor the execution time should be as follows:

26.67+(26.67×0.7) = 45.339

= 45 seconds

Therefore. the execution period for a single processor is about 45 seconds.

The work is performed in parallel, whereas the program is already being parallelized. The overall function ought to be shared between the processor. The time is shortened to around half. Hence the duration taken will be 8 seconds after parallelization.

Theoretical execution time would be Tp > T infinity.

Thus, T infinity<45

The theoretical processing interval on processor count P1/2 would therefore be less than 8 seconds. Because, the time required during parallelization was just that.
