Answer:

<em>Block all ports except 80</em>

Explanation:

We can make our network more defensive by blocking all ports except 80. This strategy can reduce the risk of attackers. If all the ports that are not in used are not in used can make system or network insecure. To enhance the security and reduce the risk of attacks we block all the ports that are not in used.

Using this strategy on people visit who need the data and attacker cannot access the system, without consent of owner.

ElenaW [278]
The most necessary point you need to follow when using a line graph, is to make your graph readable. So, the reason why is it inportant to only graph 1 - 3 series of data is that more than 3 series of data causes too many lines on the graph, which makes ti confusing to read. The last option is the correct one.

Help me understand why it does not loop correctly and how to make the converter a continious loop? What am I doing wrong and how
Aleksandr-060686 [28]

Answer:

The control loop responds to

the overcharged VOUT with a skipped pulse to

regulate VOUT to the correct DC voltage. Other

converters may respond differently when the

minimum on-time is violated. For example, the

fSW may begin to decrease or VOUT may become

regulated to a higher voltage

Explanation:

If you are trying to make a loop run a certain number of time in Python, then...

To repeat something a certain number of times, you may:

1. Use range or xrange for i in range(n): # do something here.

2. Use while i = 0 while i < n: # do something here i += 1.

3. If the loop variable i is irrelevant, you may use _ instead for _ in range(n): # do something here _ = 0 while _ < n # do something here _ += 1.

g Write a Racket function (process lst1 lst2) that processes the corresponding elements of the two lists and returns a list. If
blagie [28]

Answer:

  1. def process(lst1, lst2):
  2.    newList = []
  3.    for i in range(0, len(lst1)):
  4.        sum = lst1[i] + lst2[i]
  5.        newList.append(sum)
  6.    return newList
  7. list1 = [1, 3, 5, 7, 9]
  8. list2 = [2, 4, 6, 8, 10]
  9. print(process(list1, list2))

Explanation:

Firstly, create a function process that takes two input lists (Line 1). In the function, create a new list (Line 2). Use a for loop to traverse through the elements of the two lists and total up the corresponding elements and add the sum to the new list (Line 3 - 5). At last, return the new list (Line 6).

In the main program, create two sample list and use them as arguments to test the function process (Line 8 - 9). We shall get the output  [3, 7, 11, 15, 19].
