Vikki [24]

Answer:

(c) the total number of bytes transferred divided by the total time between the first request for service and the completion on the last transfer

Explanation:

disk bandwidth

  • Disk read and write in bandwidth is strongly dependent on the size of the block.
  • Disk read / write bandwidth on Commodity hardware varies from slower like 10 MB/s  to faster like 500 MB/s.

This difference can be represented by the following rules:

  • Reading / writing big data is faster than reading / writing small blocks of data
  • Writing is faster than reading
  • Solid state drives are faster than spinning disks, especially for very small reads / rights

so we can say Disk bandwidth is the total number of bytes transferred divided by  the total time between the first request for service and the completion of the last transfer.

In Python please:
g100num [7]

Answer:

def compute_pay(number_of_hours, rate_of_pay):

   if number_of_hours > 40:

       pay_for_week = (40*rate_of_pay)+((number_of_hours-40)*\

                                                (rate_of_pay+rate_of_pay*0.5))

   else:

       pay_for_week = number_of_hours*rate_of_pay

   if pay_for_week >= 375:

       print("Paying %d by direct deposit" % pay_for_week)

   else:

       print("Paying %d by mailed check" % pay_for_week)

Explanation:

  1. We define the computer pay function that receives the number of hours worked in a week and the rate of pay
  2. From the test cases we deduce that if a worker works more than 40 hours a week an extra payment is given, you can calculated it as follow: (40 * rate_of_pay) + ((number_of_hours - 40) * (rate_of_pay + rate_of_pay * 0.5))
  3. If a worker works less than 40 hours the payment is calculated as follow: pay_for_week = number_of_hours * rate_of_pay
  4. If the pay for week is equal or greater than 375 we print a payment by direct deposit otherwise we print payment by mailed check

What two statements about IPv6 addresses are true? This task contains the radio buttons and checkboxes for options. The shortcut
Oliga [24]

Answer:

A and C

Explanation:

Option A:

In IPv6 there is a rule to reduce an IPv6 address when there are two or more consecutive segments of zeros just one time. This rule says that you can change the consecutive zeros for “::”  

Here is an example

How to reduce the following IPv6 address?

ff02:0000:0000:0000:0000:0000:0000:d500

Ans: ff02::d500

Example 2:

2001:ed02:0000:0000:cf14:0000:0000:de95

Incorrect Answer -> 2001:ed02::cf14::de95  

Since the rule says that you can apply “::” just one time, you need to do it for a per of zero segments, so the correct answer is:

Correct Answer -> 2001:ed02::cf14:0:0:de95

Or

2001:ed02:0:0:cf14::de95

Option C:

Since in IPv6 there are 2^{128} available addresses which means 340.282.366.920.938.463.463.374.607.431.768.211.456 (too many addresses), there is no need of NAT solution, so each device can have its own IP address by the same interface to have access through the internet if needed. If not, you can block the access through internet by the firewall.
