This graph shows the efficiencies of two different algorithms that solve the same problem. Which of the following is most efficient?

Answer:

String longest = "";

Explanation:

The initialization that would allow the method to work as intended would be the following

String longest = "";

This is because the method is looping through the array provided as an argument and comparing each word in the array with the word saved inside the variable called longest. The length of both are compared and if the word in the array is longer than the string saved in the variable longest then it is overwritten with the word in the array.

1. Multistage database.

2. Stationary database.

3. Virtual database.

4. Distributed database.

Explanation:

A database management system (DBMS) can be defined as a collection of software applications that typically enables computer users to create, store, modify, retrieve and manage data or informations in a database. Generally, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.

There are four (4) major types of database in a data warehouse and these are;

1. Multistage database: used for concise as well as detailed historical data. It provides summarized data which can be used by an employee for short-term decision making.

2. Stationary database: used where access to data is rare i.e business firms who do not access data frequently. In order to use this database, the users must have an access to metadata store and thus, directly having access to the data on a source system.

3. Virtual database: used for accessing data in diverse applications using middleware. This type of database is dependent on having access to information on various databases.

4. Distributed database: used by an organization that runs several businesses. Therefore, this type of database are usually located or situated in various geographical regions.

A computer is a programmable device that can automatically perform a sequence of calculations or other operations on data once programmed for the task. It can store, retrieve, and process data according to internal instructions. A computer may be either digital, analog, or hybrid, although most in operation today are digital. Digital computers express variables as numbers, usually in the binary system. They are used for general purposes, whereas analog computers are built for specific tasks, typically scientific or technical. The term "computer" is usually synonymous with digital computer, and computers for business are exclusively digital.

The core, computing part of a computer is its central processing unit ( CPU), or processor. ... A computer system, therefore, is a computer combined with peripheral equipment and software so that it can perform desired functions.

Explanation:

In the code, the "dic_sorted" method is used, which accepts a data variable as a parameter, and inside the method, a split method and an empty dictionary are defined, that converts and holds the value by alphabetical order, for this it defines three for loops.

In the first for loop, it holds a value in the dictionary, and in the second loop it converts a value into the lower case, and in the third loop, it stores the value in its alphabetical order.

import random

lotterylist = []

for number in range(7):

   lotterylist.append(random.randint(0,9))

for number in lotterylist:

   print(number, end = ', ')

Explanation:

This line imports the random library

import random

This line creates an empty list

lotterylist = []

The instructions in this loop will be performed 7 times

for number in range(7):

This line generates a random number between 0 and 9 (inclusive) and then appends the number into lotterylist

   lotterylist.append(random.randint(0,9))

This iterates through lotterylist    

for number in lotterylist:

This prints the content of the list on a line (seperated by comma)

   print(number, end = ', ')

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

It will take 19.19 ms to transfer sector 1 on track 8 to sector 1 on track 9

The given parameters are:

[tex]d_r = 3600 rpm[/tex] --- the disk rotation

[tex]s=32[/tex] --- the sectors in a track

Calculate the time (t) to complete one revolution

[tex]t = \frac{60}{d_r}[/tex]

[tex]t = \frac{60}{3600}[/tex]

[tex]t = \frac{1}{6}[/tex]

So, the time to read/write to a sector is:

[tex]T = \frac{t}{s}[/tex]

This gives

[tex]T = \frac{1/6}{32}[/tex]

[tex]T = \frac{1}{192}[/tex]

Convert to ms

[tex]T = \frac{100}{192}[/tex]

[tex]T = 0.52ms[/tex]

Next, calculate the rotation time to head up sector 1 on track 8 to sector 1 on track 9

This is calculated as:

[tex]r_t = t \times \frac{s-1}{s}[/tex]

So, we have:

[tex]r_t = \frac 16 \times \frac{32-1}{32}[/tex]

[tex]r_t = \frac 16 \times \frac{31}{32}[/tex]

[tex]r_t = 0.1615[/tex]

Convert to ms

[tex]r_t = 0.1615 \times 100[/tex]

[tex]r_t = 16.15[/tex]

So, the required time to transfer sectors is:

Time = 2 * Time to read/write to a sector + Seek time + Rotation time

This gives

[tex]Time = 2 \times 0.52 + 2 + 16.15[/tex]

[tex]Time = 19.19[/tex]

Hence, it will take 19.19 ms to transfer sector 1 on track 8 to sector 1 on track 9

Answer:

Explanation:

The following code is written in Python. It is a function called divide_by_x and takes the user inputs as described. It then raises x to the third power and divides user_num by that number. This gives the same result as user_num divided by x three times. The answer is saved in the variable answer which is then returned to the user.

def divide_by_x(user_num, x):

   answer = user_num / (x**3)

   return answer

The program is an illustration of the division arithmetic operation.

The program in Python, where comments are used to explain each line is as follows:

#This gets input for user_num

user_num = int(input())

#This gets input for x

x = int(input())

This loop is repeated three times

for i in range(1,4):

       #This divides user_num by x, each time

       user_num /= x

       #This prints the required output

       print(user_num)

At the end of the program, user_num is divided three times by x and then printed.

Answer:

885 μs

Explanation:

Given that:

Switch via = 100 Mbps links

The propagation delay for each link = 25μs.

Retransmitting a received packet = 35μs

To determine:

The total time required to transmit 40,000 bits from A to B.

Considering the fact as a single packet:

Transmit Delay / link = size/bandwith

= 4×10⁴ bits / 100 × 10⁶ bits/sec

= 400 μs

The total transmission time = ( 2 × 400 + 2 × 25 + 35) μs

= (800 + 50 + 35) μs

= 885 μs

Answer:

Condition one - 1 time

Condition two - 2 times

Explanation:

Given

The above code segment

Required

Determine the number of times each print statement is executed

For condition one:

The if condition required to print the statement is:  if (arr[row][col] >= arr[row][col - 1])

For the given data array, this condition is true only once, when

[tex]row = 1[/tex]  and  [tex]col = 2[/tex]

i.e.

if(arr[row][col] >= arr[row][col - 1])

=> arr[1][2] >= arr[1][2 - 1]

=> arr[1][2] >= arr[1][1]

=> 5 >= 3 ---- True

The statement is false for other elements of the array

Hence, Condition one is printed once

For condition two:

The if condition required to print the statement is:  if (arr[row][col] % 2 == 0)

The condition checks if the array element is divisible by 2.

For the given data array, this condition is true only two times, when

[tex]row = 0[/tex]  and  [tex]col = 1[/tex]

[tex]row = 1[/tex]  and  [tex]col = 0[/tex]

i.e.

if (arr[row][col] % 2 == 0)

When [tex]row = 0[/tex]  and  [tex]col = 1[/tex]

=>arr[0][1] % 2 == 0

=>2 % 2 == 0 --- True

When [tex]row = 1[/tex]  and  [tex]col = 0[/tex]

=>arr[1][0] % 2 == 0

=> 4 % 2 == 0 --- True

The statement is false for other elements of the array

Hence, Condition two is printed twice
