Answer:
False
Explanation:
A password in a one factor or multi-factor authentication is a mechanism not of what an entity has but what they know.
One factor authentication makes use of passwords only, to secure a user account. A multi-factor authentication uses two or more mechanisms for securing user accounts. It ask the question of what the users know (for password), what they have (security token, smart cards), and who they are(biometrics).
Answer:
False
Explanation:
The authentication mechanism especially the multi-factor authentication uses three types of authentication form factors.
i. What the entity knows: This includes what the entity knows and can always remember. Such as passwords and PINs
ii. What the entity has: This includes physical items that belong to the entity such as smart cards and token generators.
iii. What the entity really is: This includes natural or body features of the entity such as its thumbprint and its palm which can be used for verification.
According to these three factors, it is evident that password is based on "what an entity knows" and not "what an entity has".

access buffer
output buffer
transmission buffer
none of the above
Answer: Output buffer
Explanation:
Each packet switches contain multiple links which are attached to it and for individually attached link the output buffer basically store packets. Then, the router send these packets into multiple links.
In output buffer, if the packets are transmitted into the links but it finds that the link is busy with the another packet for transmission. Then, that particular packet needs to be wait in output buffer.
Therefore, the output buffer is the correct option.
Contrast is the amount of variation between the lightest highlight and the darkest shadow in a particular image.
The visual ratio of various tones in an image is known as contrast in photography. The textures, highlights, shadows, colors, and clarity of a photograph are the result of this difference. The range of brightness, from lightest to darkest, in an image is known as contrast. Very bright highlights and very dark shadows characterize a high-contrastphotograph. High contrast occurs when an image's shadows or highlights are occasionally almost entirely black or almost entirely white. A crucial component for expressing particular moods in your photos is contrast. High contrast images stand out, reveal the subject's textures, and convey a sense of aplomb, vigor, and power. In both street photography and wildlife photography, high contrast is frequently used. Images with low contrast sometimes have a dreamlike quality.

Explanation:
The National FFA Organization is a youth organization that originally aimed to encourage the youth to venture into agriculture by offering agriculture education to youth in high schools and middle schools. In recent years they started offering education in other areas such as business and technology.
The FFA is quite famous and has had and still has a lot of members. It is of no surprise therefore that some of their alumni are now stars. Famous Country musician Tim McGraw is one such alumni and he was a member of the FFA in his hometown of Start, Louisiana.
Other stars who were part of the FFA include; Taylor Swift and Sterling Martin.

Hint: Use two vectors, one for the strings, another for the frequencies.
Your program must define and use the following function: int GetFrequencyOfWord(vector wordsList, string currWord)
Answer:
/ declare the necessary header files.
#include <iostream>
#include <string>
#include <vector>
using namespace std;
// declare the main function.
int main()
{
// declare a vector.
vector<string> words;
vector<int> counts;
// declare variables.
int size;
string str;
cin >> size;
// start the for loop.
for(int i = 0; i < size; ++i)
{
// input string.
cin >> str;
words.push_back(str);
}
// start the for loop.
for(int i = 0; i < size; ++i)
{
int count = 0;
// start the for loop.
for(int j = 0; j < words.size(); ++j)
{
// check the condition.
if(words[j] == words[i])
{
count++;
}
}
counts.push_back(count);
}
// start the for loop.
for(int i = 0; i < size; ++i)
{
// display result on console.
cout << words[i] << "\t" << counts[i] << endl;
}
return 0;

Answer:
The correct answer is 1000 MIPS.
Explanation:
Using the rule of three you can solve the needed cycles to complete 1.000.000 instructions.
1.000.000 instructions multiplied by 2 cycles, divided by 1 instruction is equal to 2.000.000 cycles to complete 1.000.000 instructions.
To find the MIPS you have to divide the frequency by the cycles needed to complete 1.000.000 instructions.
MIPS = 2GHZ / 2.000.000 cycles = 1000 MIPS.
