Deep Web is called invisible web as it is not accessible or searchable to standard search engines like Google. Search engines cannot index the contents of these sites. However such sites do not requires specialized browsers to access. So b is not a suitable choice.

Dark Web: It is a part of Deep Web sites but it requires specialized software and browsers to access. These sites cannot be indexed and cannot be searchable through standard search engines. This is also called dark side of the world wide web darker which is frequently used by criminals, hackers, black markets, hit-men. Illegal activities on a massive level is takes place in the dark web such as access to stolen sensitive information, malware, drug trade and terrorist operations.

Crypto-Net is a kind of neural network which works with encrypted data which can make a prediction based on the data without disclosing the data and prediction to the 3rd party. So d is not a suitable option.

An electric kettle has the resistance of 30ohms what will flow when it connected to a 240v supply... find also the power rating
SVEN [57.7K]

Answer:

Power = 1920 Watts or 1.92 Kilowatts

Explanation:

Given the following data;

Resistance = 30 Ohms

Voltage = 240 Volts

To find power rating of the kettle;

Mathematically, the power consumption of an electric device is given by the formula;

Power = voltage²/resistance

Substituting into the formula, we have;

Power = 240²/30

Power = 57600/30

Power = 1920 Watts or 1.92 Kilowatts

for (int i = 0; i < size; ++i) {

if (arr[i].age == age && arr[i].name == name && arr[i].gpa == gpa) {

index = i;

break;

}

}

}

if (index != -1) {

for (int i = index; i < size - 1; ++i) {

arr[i] = arr[i + 1];

}

size--;

3.What are the pros and cons of using a linked implementation of a sparse matrix, as opposed to an array-based implementation
weqwewe [10]

Answer:

speed and storage

Explanation:

The pros and cons of both are mainly in regards to speed and storage. Due to linked lists elements being connected to one another it requires that each previous element be accessed in order to arrive at a specific element. This makes it much slower than an array-based implementation where any element can be quickly accessed easily due to it having a specific location. This brings us to the other aspect which is memory. Since Arrays are saved as a single block, where each element has a specific location this takes much more space in the RAM as opposed to a linked implementation which is stored randomly and as indexes of the array itself.

Array Implementation:

  • Pros: Much Faster and Easier to target a specific element
  • Cons: Much More Space needed

Linked Implementation

  • Pros: Less overall space needed
  • Cons: Much slower speed.
