Does magnetic tape require a laser to read data?

Answers

Answer 1

Answer:

No the magnetic tape requires a tape drive mechanism

Explanation:

The data in magnetic tape consists of information that has been digitized into discrete numbers by means of of a recording device which can also be able to read the recorded data on the tapes

As the magnetized tape passes under a current carrying conductor, the data on the magnetized surface can be sensed

Due to the arrangement of the magnetic tapes in their stored format, the process of retrieving information makes use of serial access such that information retrieval is slow.

When looking at aggregated logs, you are seeing a large percentage of Windows hosts connecting to an Internet Protocol (IP) address outside the network in a foreign country. Why might this be worth investigating more closely

Answers

Answer:

"It might demonstrate a malware infection" is the correct response.

Explanation:

Because once glancing at aggregate data log files, clients could perhaps actually listen to road conditions but instead correlation coefficient.  For obvious reasons, whenever you see a significant portion of presenters designed to connect to something like a particular destination out beyond your channel, it might have been worthwhile to investigate quite tightly, although it might demonstrate malware.

Can you help me with these AP Computer Science Questions. (THIS IS DUE BY 1:30 PM today) you have to evaluate the Boolean Expressions.

Answers

Answer + Explanation:

'and' -> both statements are 'True' to evaluate as 'True'.

'or' -> at least one statement is 'True' to evaluate as 'True'.

1. True (grade has the value of 82, so the statement evaluates to 'True').

2. True (Both statements are true, this expression evaluates to 'True').

3. False (Both statements are false, this expression evaluates to 'False').

4. True (the != operator means not equal. Since the 'name' variable holds the string 'Rumpelstiltskin', name != 'Rumpelstiltskin' evaluates to 'False'. The 'not' operator returns the opposite of the given Boolean expression, so this expression evaluates to 'True').

5. True (name == 'Rumpelstiltskin' evaluates to 'True', so this expression is true).

6. False (All statements evaluate to 'False').

7. True (All statements evaluate to 'True').

8. False (All statements evaluate to 'True' except for not(x == - 3) which evaluates to 'False', so the whole statement now becomes false).

9. True (grade+5 < 90 and grade >= 80 evaluates to 'True', so this whole expression becomes true).

10. True (grade > 0 and x % 2 == 1 evaluates to 'True')

Hope this helps :)

In this exercise we have to have knowledge about computation, in this way it will be possible to analyze the code in python. So we will have:

1) True

2) True

3) False

4) True

5) True

6) False

7) True

8) False

9) True

10)False

In this way to understand the code we have to make clear an important point, that is:

'and' -> both statements are 'True' to evaluate as 'True'. 'or' -> at least one statement is 'True' to evaluate as 'True'.

1) The grade has the advantage of 82, so the charge evaluates to 'True'.

2) Both charge exist valid, this facial appearance evaluates to 'True'.

3) Both account of finances happen dishonest, this facial appearance evaluates to 'False'.

4)The 'not' manipulator returns the opposite of the likely Boolean verbalization, so this facial appearance evaluates to 'True'.

5) The name == 'Rumpelstiltskin' evaluates to 'True', so this facial appearance exist real.

6) All account of finances judge to 'False'.

7) All assertion judge to 'True'.

8) All account of finances judge to 'True' except that not(x == - 3) that evaluates to 'False', so all affidavit immediately enhance dishonest.

9) The grade+5 < 90 and grade >= 80 evaluates to 'True', so this whole verbalization enhance real.

10) The grade > 0 and x % 2 == 1 evaluates to 'True'.
