Answer:

Worm malware

Explanation:

The worm operates destructively as it replicates itself and keeps spreading within a computer or network. It takes advantage of software and security vulnerabilities.

Once a computer or network is infected, worms replicate themselves, therefore using up the computer and network resources. Among others, one of the major missions of worms is to create a backdoor into a network, to be able to enable the attacker to carry out a more devastating attack.

Since worms take advantage of weak security in the Operating system, it is very important to constantly update the security features of the Operating system. Users must be careful of the emails they open and attachments they download.

In this exercise we look at memory locality properties of matrix computation. Th e following code is written in C, where element
Sonja [21]

Answer:

Explanation:

temporal locality can be defined as: when a particular memory  is referenced or accessed several times  within a specific period of time. In the question, i think the variable that exhibit temporal locality are I, J and 0(all the variable). This is because the variable J and 0 are accessed several times within the loop. I would not have been part of it, but in the A[I][J]=B[I][0]+A[J][I], the variable "I" is also accessed in the addition. this is why it is part of the temporal locality.

Imagine you have a 10-character string stored in the variable myString. You want to pull out the first five characters. Which of
Andre45 [30]

Answer:

b. myString[:-5]

d. myString[-15:-5]

Explanation:

I believe you have a typo in d. It must be d. myString[-15:-5]

Slicing can be done:

myString[starting_index, stopping_index, step] (step is optional). If you do not specify the starting index, it will start from the 0 as in b. If you write a range that is not in the range, as in d, Python will replace it with either 0 or length of the string (In this case, it is replaced with 0 because the starting index must be smaller than stopping index)

a. myString[5] → This will give you the sixth character

b. myString[:-5] → This will give you the first five characters

c. myString[0:6] → This will give you the first six characters

d. myString-15:-5] → This will give you the first five characters

e. myString[0:10:2] → This will give you the first, third, fifth, seventh, and ninth characters

Gwar [14]

Sean is using FUNCTION POINT (d) method for forecasting the time and cost of developing a customized software program by looking at the number of inputs, outputs, inquiries, files, and interfaces.

Explanation:

  • The function point is a "unit of measurement" to express the amount of business functionality an information system (as a product) provides to a user.
  • The outcome of a function point count provides the metric 'unit of software delivered' and can be used to assist in the management and control of software development, customisation or major enhancements from early project planning phases, through to the ongoing support of the application.
