Which of the following behaviors does not harm a company if your employment is terminated?
saul85 [17]

Answer:

D. notifying your employer of all accounts you have access to, and requesting that they change all passwords before you leave

Explanation:

Assuming your employment is terminated, notifying your employer of all accounts you have access to, and requesting that they change all passwords before you leave is a behavior that would not harm a company. In the true and actual sense, making such suggestions is commendable because it would go a long way to cause more good rather than harm the company.

Some mischievous and malicious employees would rather not tell so they can still have an unauthorized access to the company's account and perpetrate various level of evil.

Hence, it is a good global practice to have a company's login credentials updated whenever an employee's employment is terminated.

Suppose that a computer can run an algorithm on a problem of size 1,024 in time t. We do not know the complexity of the algorith
Setler79 [48]

Answer:

Time Complexity of Problem - O(n)

Explanation:

When n= 1024 time taken is t. on a particular computer.

When computer is 8 times faster in same time t , n can be equal to 8192. It means on increasing processing speed input grows linearly.

When computer is 8 times slow then with same time t , n will be 128 which is (1/8)th time 1024.

It means with increase in processing speed by x factor time taken will decrease by (1/x) factor. Or input size can be increased by x times. This signifies that time taken by program grows linearly with input size n. Therefore time complexity of problem will be O(n).

If we double the speed of original machine then we can solve problems of size 2n in time t.

julia-pushkina [17]

Complete Question:

Recall that with the CSMA/CD protocol, the adapter waits K. 512 bit times after a collision, where K is drawn randomly. a. For first collision, if K=100, how long does the adapter wait until sensing the channel again for a 1 Mbps broadcast channel? For a 10 Mbps broadcast channel?

Answer:

a) 51.2 msec.  b) 5.12 msec

Explanation:

If K=100, the time that the adapter must wait until sensing a channel after detecting a first collision, is given by the following expression:

  • Tw = K*512* bit time

The bit time, is just the inverse of the channel bandwidh, expressed in bits per second, so for the two instances posed by the question, we have:

a) BW  = 1 Mbps = 10⁶ bps

⇒ Tw = 100*512*(1/10⁶) bps = 51.2*10⁻³ sec. = 51.2 msec

b) BW = 10 Mbps = 10⁷ bps

⇒ Tw = 100*512*(1/10⁷) bps = 5.12*10⁻³ sec. = 5.12 msec

The following method is intended to remove all values from the ArrayList a that have the same value as val; however, this method
Alona [7]

Answer:

ArrayList a contains [2, 3, 3, 3, 4, 5, 3, 2, 1]

Explanation:

Given

The removeValue method

Required

The content of ArrayList a, after the method is called

From the question, we understand that arraylist a is:

a= [2, 3, 4, 3, 3, 4, 4, 5, 4, 3, 2, 1]

val =4

The function fails when the value to be removed appear consecutively in the list.

4 appears in index 5 and 6 of the list. Only one of the 4's will be removed

So, the updated list will be: [2, 3, 3, 3, 4, 5, 3, 2, 1]
