Answer: c. Depending on context the same sequence of bits may represent different types of information.

Explanation:

The options for the question are:

A. Computing devices use patterns of bits to represent complex information

B. Abstraction helps represent complex information by surfacing complexity that might otherwise be hidden

C. Depending on context the same sequence of bits may represent different types of information

D. Common abstractions that are represented by computing devices include numbers, characters, and color.

The following are true of how computers represent complex information:

• Computing devices use patterns of bits to represent complex information

• helps represent complex information by surfacing complexity that might otherwise be hidden

• Common abstractions that are represented by computing devices include numbers, characters, and color.

Therefore, the option that is not true of how computers represent complex information is that "depending on context the same sequence of bits may represent different types of information".

Answer:

d. Port mirror

Explanation:

Port mirroring is a method to monitor network traffic and it is used in the Intrusion Detection Systems. It is also called Switched Port Analyzer and is used to analyse the network errors. This technique basically copies the network packets and sends or transmits these copied packed from one port to another in a network device such as a switch. This means that this technique is used to copy the network packets from one switch port and send the copy of these packets to another port where these packets are monitored. This is how it analyses the network errors and incoming traffic for irregular behavior and also this can be done without affecting the normal operation of the switch and other network processes. It is simple, inexpensive and easy to establish and use. The most important advantage of using mirrored ports is that it catches the traffic on several ports at once or can capture all of the network traffic.

A 1.17 g sample of an alkane hydrocarbon gas occupies a volume of 674 mL at 28°C and 741 mmHg. Alkanes are known to have the gen

Nina [5.8K]

Answer:

C3H8

Explanation:

Step 1:

Data obtained from the question. This includes the following:

Mass of alkane = 1.17g

Volume (V) = 674 mL

Temperature (T) = 28°C

Pressure (P) = 741 mmHg.

Gas constant (R) = 0.08206 atm.L/Kmol

Step 2:

Conversion to appropriate unit.

For Volume:

1000mL = 1L

Therefore, 674mL = 674/1000 = 0.674L

For Temperature:

Temperature (Kelvin) = Temperature (celsius) + 273

Temperature (celsius) = 28°C

Temperature (Kelvin) = 28°C + 273 = 301K

For Pressure:

760mmHg = 1atm

Therefore, 741 mmHg = 741/760 = 0.975atm

Step 3:

Determination of the number of mole of the alkane..

The number of mole of the alkane can be obtained by using the ideal gas equation. This is illustrated below:

Volume (V) = 0.674L

Temperature (T) = 301K

Pressure (P) = 0.975atm

Gas constant (R) = 0.08206 atm.L/Kmol

Number of mole (n) =?

PV = nRT

n = PV /RT

n = (0.975 x 0.674)/(0.08206x301)

n = 0.0266 mole

Step 4:

Determination of the molar mass of the alkane.

Mass of alkane = 1.17g

Number of mole of the alkane = 0.0266mole

Molar Mass of the alkane =?

Number of mole = Mass/Molar Mass

Molar Mass = Mass/number of mole

Molar Mass of the alkane = 1.17/0.0266 = 44g/mol

Step 5:

Determination of the molecular formula of the alkane.

This is illustrated below:

The general formula for the alkane is CnH2n+2

To obtain the molecular formula for the alkane we shall assume n = 1, 2, 3 or more till we arrive at molar Mass of 44.

When n = 1

CnH2n+2 = CH4 = 12 + (4x1) = 16g/mol

When n = 2

CnH2n+2 = C2H6 = (12x2) + (6x1) = 30g/mol

When n = 3

CnH2n+2 = C3H8 = (12x3) + (8x1) = 44g/mol

We can see that when n is 3, the molar mass is 44g/mol.

Therefore, the molecular formula for the alkane is C3H8.

Write a loop that prints each country's population in country_pop. Sample output for the given program.

Illusion [34]

Answer:

Correct code for the above question which is written after the defined list to display the output.

for x,y in country_pop.items(): #for loop to prints the list items.

print(str(x)+" has "+str(y)+" people") #print function to print the value.

Output:

The above code is in python language which display the output as the above question demands.

Explanation:

The above question code is written in python language to display the result, but this code is not correct.
The above code needs a 'for' loop, which will render the list item one by one.
The above-list defined in the form of key-value pair, So there is a need for the ''item" function which is the part of the python dictionary to display the list items.
There also needs to define the two variables in the for loop, one is for key and the other is for value.

KATRIN_1 [288]

Paired programming:

Paired programming is a new technique where one person gets one another to write the code. Here one will write the code and other will start verifying as the type.

So we might think it is waste to employ two person for same task but it is not so. There are many benefits in incorporating this technique. Let us see those benefits one by one.

Inter-personal skill gets improved

Lower amount of coding mistake

Learn from each other

Peer review enhance collaboration

Challenges expect to arise during pair-programming

Two heads are superior to one. On the off chance that the driver experiences a hitch with the code, there will be two of them who'll take care of the issue.

Builds up your staff's relational aptitudes. Working together on a solitary venture encourages your group to welcome the estimation of correspondence and collaboration.

Overcome Method

The most ideal approach to move toward blending is to accomplice two software engineers and have them share a PC. The pair ought to have the option to choose how to part the work, and it is prudent that they should switch jobs frequently.

ankoles [38]

This is an incomplete question. The complete question is given below:

Mike has never used slide presentation software before but he needs to create a presentation by the end of the week what resource would be most helpful to mike

a. The 350-page printed manual from the slide presentation software publisher

b. A free tutorial the slide presentation software publisher has posted on the company website

c. A trouble-shooting website created by a third party

d. The 350-page online manual from the slide presentation software publisher

Answer:

b - A free tutorial the slide presentation software publisher has posted on the company website

Explanation:

As Mike has a short time and no prior experience with a slide software, then in this scenario, the best, simplest and fastest way to learn and create a presentation a free tutorial which the slide presentation software publisher has posted on the company website as this is the same company that has created this particular software so he can be rest-assured that the resource he is relying on is authentic and up-to-date with information on latest features.

Moreover, it's efficient and quick way to learn from a free tutorial rather than from 350-page printed or online manual especially for a beginner.

Besides, his purpose is to create the presentation using the software and not trouble-shooting so trouble-shooting website created by a third party is not useful for him and it also might not be authentic or updated as well.
