Answer:

All of the mentioned views could be looked as an additional layer in the table which enables us to protect intricate or sensitive data based upon our needs.

Explanation:

View is a virtual table which executed a pre compiled query. It is a table in which selective portion of the data can be seen from one or more tables. Queries are not allowed in indexed views and adding column is not possible. Views can be looked as an additional layer in the virtual table which protects sensitive data.

Given a collection of n nuts and a collection of n bolts, arranged in an increasing order of size, give an O(n) time algorithm t
kari74 [83]

Answer:

See explaination

Explanation:

Keep two iterators, i (for nuts array) and j (for bolts array).

while(i < n and j < n) {

if nuts[i] == bolts[j] {

We have a case where sizes match, output/return

}

else if nuts[i] < bolts[j] {

this means that size of nut is smaller than that of bolt and we should go to the next bigger nut, i.e., i+=1

}

else {

this means that size of bolt is smaller than that of nut and we should go to the next bigger bolt, i.e., j+=1

}

}

Since we go to each index in both the array only once, the algorithm take O(n) time.

Musya8 [376]

Answer:

Explanation:

If L(D1) = L(D2), the D has every state being final

If L(D1) = L¯(D2), the D has every state being final

If L(D1) = ∅, then L(D) = L(D2).

If L(D1)=Σ, L(D) = L(D2)

Ket [755]

Answer:

A. 4 CPUs and 6 megabyte cache memory

B. 1.3157 x10^-9 nanoseconds

Explanation:

The Intel core i5 7500 is a seventh generation central processing unit with a 4 CPU core and a 6 megabyte cache memory. It executes task at a clock cycle of 5 clock cycle at a speed of 3.8 GHz.

The relationship between frequency and clock cycle is,

Clock cycle = 1 / ( frequent).

So, One clock cycle = 1 / 3.8 GHz

= 0.3 x10^-9

For five clock cycles = 5 x 0.3 x10^-9

= 1.3157 x10^-9 nanoseconds.
