Consider a disk that rotates at 3600 rpm. The seek time to move the head between adjacent tracks is 2 ms. There are 32 sectors p

er track, which are stored in linear order from sector 0 through sector 31. The head sees the sectors in ascending order. Assume the read/write head is positioned at the start of sector 1 on track 8. There is a main memory buffer large enough to hold an entire track. Data is transferred between disk locations by reading from the source track into the main memory buffer and then writing the data from the buffer to the target track. a. How long will it take to transfer sector 1 on track 8 to sector 1 on track 9

Answer:

19.71 ms

Explanation:

The disk rotates at 3600 rpm, hence the time for one revolution = 60 / 3600 rpm = 16.67 ms.

Hence time to read or write on a sector = time for one revolution / number of sectors per track = 16.67 ms / 32 sectors = 0.52 ms

Head movement time from track 8 to track  9 = seek time = 2 ms

rotation time to head up sector 1 on track 8 to sector 1 on track 9 = 16.67 * 31/32 = 16.15 ms

The total time = sector read time +head movement time + rotational delay + sector write time = 0.52 ms + 2 ms + 16.15 ms + 0.52 ms = 19.19 ms

(1) Prompt the user to enter five numbers, being five people's weights. Store the numbers in an array of doubles. Output the arr
Mashutka [201]

Answer:

weights = []

total = 0

max = 0

for i in range(5):

   weight = float(input("Enter weight " + str(i+1) + ": "))

   weights.append(weight)

   total += weights[i]

   if weights[i] > max:

       max = weights[i]

average = total / 5

print("Your entered: " + str(weights))

print("Total weight: " + str(total))

print("Average weight: " + str(average))

print("Max weight: " + str(max))

Explanation:

Initialize the variables

Create a for loop that iterates 5 times

Get the values from the user

Put them inside the array

Calculate the total by adding each value to the total

Calculate the max value by comparing each value

When the loop is done, find the average - divide the total by 5

Print the results

A large industrial machine is able to monitor environmental conditions and quickly shut down and sound an alarm when it detects
Tamiku [17]

The feature of technology that allows this to happen is d. reduced latency.

Latency is the amount of time it takes for data to be transmitted in a network. Reduced latency therefore refers to a situation where data is transmitted with speed.

Reduced latency allows:

  • better communication
  • reduced lag and,
  • better gaming

The machine in question is only able to quickly sound the alarm because it has low latency.

In conclusion, we can say that low latency enables the machine above to sound the alarm quickly which means that low latency is important to the safety of that environment.

Options for this question include:

a. improved bandwidth

b. connection density

c. effective range

d. reduced latency

This motherboard already has 1GB of RAM installed in the DIMM1 slot. The customerwould like to upgrade to 4GB total memory, use
Luden [163]

Answer:

The two phases to the context of this discussion are listed follows.

Explanation:

  • <u>Solution 1</u>: Delete 1 GB of current RAM as well as install another DIMM0 Chan A slot through one 2 GB of double-channel RAM. (thinkable unless the 2 GB RAM is provided by the motherboard in what seems like a DIMM0 Chan A slot)  
  • <u>Solution 2</u>: whether there's an unused or blank slot, perhaps one 1 GB dual-channel Ram could be mounted in some other slot at around the same speed or frequency.  

It's quite safer to mount memory with appropriate frequencies across both situations.
