If it is impractical to place guest users in a secure network, isolated from the production network by firewall barriers, then:

IgorLugansk [536]

Answer:

specific areas of access should be determined and they should be as restrictive as possible.

Explanation:

According to my research on security features of networks , I can say that based on the information provided within the question then specific areas of access should be determined and they should be as restrictive as possible. This would provide the highest level of security while still allowing production to be smooth.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

Using a "word" of 5 bits, list all of the possible signed binary numbers and their decimal equivalents that are represent able i

Vsevolod [243]

Answer:

i). Signed magnitude

Five bit representation = 11111

For positive 5 bit representation = 01111 = +15

For negative 5 bit representation = 11111 = -15

ii). One's complement

For positive 5 bit representation = 01111 =+15

For negative 5 bit representation = 10000 = -15

iii). Two's compliment

For positive 5 bit representation = 01111 = -15

For negative 5 bit representation = 10001 = +15

Using Sequential Search on an array of size n, the search key is definitely present in the array. The probability of matching th

MissTica

Answer:

(11n-5) / 12 is correct answer.

Explanation:

The Probability that key will match to nth term = 1/2

The Probability that key will match to n-1th term = 1/3

As all other probabilities are equal

The Total Probability that key matches to any of 1 to n-2 index = 1 - 1/2 - 1/3 = 1/6

The Probability that key matches to any of 1 to n-2 index = (1/6) / n-2 = (1/6)* (n-2))

Let P(i) = Probability that key matches to ith index.

The Average time complexity = 22 i=1 P(i) * i

The Average time complexity = 1/(6(n-2) * ( sum of 1 to n-2 ) + (n-1) / 3 + n/2

The Average time complexity = 1/(6(n-2) * ( n-2)*(n-1) / 2 + ( n-1) / 3 + n/2

The Average time complexity = 1/6 * (n-1)/2 + (n-1)/3 + n/2

The Average time complexity = (n-1)/12 + (n-1)/3 + n/2

The Average time complexity = (n-1 + 4 * n - 4 * 1 +6 * n)/12

The Average time complexity = 11n-5 / 12

so (11n-5) / 12 is correct answer.
