Suppose two hosts, A and B, are separated by 15,000 kilometers and are connected by a direct link of R = 5 Mbps. Suppose the propagation speed over the link is 2.5 * 108 meters/sec.How long does it take to send a 1,500,000 bit file, assuming it is sent continuously?

Answers

Answer:

360 msec

Explanation:

Data provided in the question:

Distance between the two hosts = 15,000 kilometer

= 1.5 × 10⁷ m    [ ∵ 1 km = 1000 m ]

Transmission rate, R = 5 Mbps = 5 × 10⁶ bits per second

Propagation speed over the link = 2.5 × 10⁸ meters/sec

Size of file to be sent = 1,500,000 bit

Now,

Propagation delay (dprop)

= Distance ÷ Speed

= ( 1.5 × 10⁷ ) ÷ (2.5 × 10⁸)

= 0.06 sec

= 60 msec           [ ∵ 1 sec = 1000 millisecond ]

Transmission delay (dtrans)

= Size of file ÷ Rate of transmission

= 1500000 ÷ ( 5 × 10⁶ )

= 0.3 sec

= 300 msec

Therefore,

Time required for transmitting the file

= Propagation delay + Transmission delay

= 60 msec + 300 msec

= 360 msec

Final answer:

The total time to send a 1,500,000-bit file from host A to host B over a distance of 15,000 kilometers at a rate of 5 Mbps is 0.36 seconds, which is the sum of the transmission time (0.3 seconds) and the propagation delay (0.06 seconds).

Explanation:

To calculate the time taken to send a 1,500,000-bit file from host A to host B separated by 15,000 kilometers at a rate of 5 Mbps, you need to consider both the transmission time and the propagation delay. The transmission time is the time required to push all the file's bits onto the wire and is given by the file size divided by the transmission rate. The second part is the propagation delay, which is the time it takes for the first bit to travel from the source to the destination.

The transmission time can be calculated as: Transmission Time = File size / Rate = 1,500,000 bits / (5 x 10⁶ bits/sec) = 0.3 seconds.

The propagation delay is the distance divided by the speed of light in the medium, which is: Propagation Delay = Distance / Speed of light = 15,000 km / (2.5 x 10⁸ m/s) = 0.06 seconds. Since the distance needs to be in meters, we convert it by multiplying by 1,000: Propagation Delay = 15,000,000 m / (2.5 x 10⁸ m/s) = 0.06 seconds.

The total time to send the file is the sum of transmission time and propagation delay: Total Time = Transmission Time + Propagation Delay = 0.3 s + 0.06 s = 0.36 seconds.

According to a study by Merrill Lynch and Gartner, what percentage of all corporate data is captured and stored in some sort of unstructured form?

Answers

Answer:

85 %

Explanation:

Historically, data warehouses had been formed using structured repetitive data that was filtered before entering the data warehouse. However, in recent years, the data warehouse has evolved due to contextual information that can now be attached to unstructured data and that can also be stored.

Those first structured relational data could not be mixed and matched for analytical subjects with unstructured textual data. But with the advent of contextualization, these types of analyzes can now be done naturally and easily.

Classic analytical processing of transaction-based data is performed in the data warehouse as it has always been done. Nothing has changed there. But now you can become analytical about contextualized data, and that form of analysis is new. Most organizations, until now, did not have to base their decision making on unstructured textual data. And now there is a new way of analysis possible in a Data Warehouse: the possibility of mixing analysis. The combined analysis is performed by a combination of structured transactional data and unstructured contextual data.

According to a research by Merrill Lynch indicates that 85 % of all coporate date is stored in some sort of unstructured form like data warehouse.

Assume you have a byte-addressable machine that uses 32-bit word (integers are 32-bit) and you are storing the following information: the string Inventory followed by a value (569)10 followed by another string Price followed by a value (49.75)10. Also, assume that floating point numbers are stored as single-precision IEEE 754 with 127 excess. a) Show (as hex numbers with word boundary) how this is stored on a big-endian machine. b) Show (as hex numbers with word boundary) how this is stored on a little-endian machine.

Answers

Final answer:

The question involves displaying how a string and numerical data will be stored in hexadecimal format in memory on a machine with both big-endian and little-endian architectures. The storage pattern involves converting ASCII strings and numbers into hexadecimal format and then storing them sequentially in memory according to the endianess. Exact hexadecimal values would require ASCII and IEEE 754 format conversions.

Explanation:

The given question involves storing textual and numerical data on a byte-addressable machine that uses 32-bit integers and single-precision floating-point format, according to the IEEE 754 standard. The data to be stored includes a string 'Inventory', a decimal integer value (569)10, a string 'Price', and a decimal floating-point number (49.75)10. We are asked to show how this information would be stored in both big-endian and little-endian representation. Firstly, we need to translate the ASCII strings and numerical values into hexadecimal, suitable for storage in memory:

The string 'Inventory' is broken into 32-bit words and converted to hexadecimal.

The integer value 569 is represented in hexadecimal as 0x00000239.

The string 'Price' is similarly broken into 32-bit words and converted to hexadecimal.

The floating-point number 49.75 is converted into IEEE 754 single-precision format and represented in hexadecimal.

For big-endian representation, the most significant byte (MSB) is stored at the lowest memory address:

Each character of 'Inventory' and 'Price' is represented by its ASCII hexadecimal value and stored in sequential memory addresses, starting with the MSB.

The integer and floating-point numbers are stored with their MSB first in the 32-bit word boundary.

For little-endian representation, the least significant byte (LSB) is stored at the lowest memory address:

Each character of 'Inventory' and 'Price' is represented in reverse order compared to big-endian.

The integer and floating-point numbers are also reversed, with the LSB first.

The exact hexadecimal values in memory would depend on the binary representations of the strings and the specifics of the IEEE 754 conversion process for the number 49.75.

You are the manager of a midsized company that assembles personal computers. You purchase most components—such as random access memory (RAM)—in a competitive market. Based on your marketing research, consumers earning over $80,000 purchase 1.5 times more RAM than consumers with lower incomes. One morning, you pick up a copy of The Wall Street Journal and read an article indicating that input components for RAM are expected to rise in price, forcing manufacturers to produce RAM at a higher unit cost. Based on this information, what can you expect to happen to the price you pay for random access memory? Would your answer change if, in addition to this change in RAM input prices, the article indicated that consumer incomes are expected to fall over the next two years as the economy dips into recession?

2.32 LAB: Input and formatted output: House real estate summary Sites like Zillow get input about house prices from a database and provide nice summaries for readers. Write a program with two inputs, current price and last month's price (both integers). Then, output a summary listing the price, the change since last month, and the estimated monthly mortgage computed as (currentPrice * 0.051) / 12 (Note: Output directly as a floating-point value. Do not store in a variable.). Ex: If the input is: 200000 210000 the output is: This house is $200000. The change is $-10000 since last month. The estimated monthly mortgage is $850.000000. Note: Getting the precise spacing, punctuation, and newlines exactly right is a key point of this assignment. Such precision is an important part of programming.

Answers

Final answer:

To solve the student's problem, input the current and last month's house prices, calculate the price change, compute the estimated mortgage, and correctly format the output presenting the figures.

Explanation:

To create a program that takes the current price and last month's price of a house as inputs, and outputs a summary of the price change and estimated monthly mortgage, follow these instructions:

First, prompt the user to input both the current price and the last month's price of the house.Calculate the difference between the current price and the last month's price.Compute the estimated monthly mortgage using the formula ((currentPrice * 0.051) / 12).Finally, format the output to include the current price, the price change, and the mortgage estimate. Ensure that spaces, punctuation, and newlines match the example precisely.

Here's how the output should look like:

This house is $200000. The change is $-10000 since last month. The estimated monthly mortgage is $850.000000.

Main answer:

```python

current_price, last_month_price = map(int, input().split())

print(f'This house is ${current_price}. The change is ${last_month_price - current_price} since last month. The estimated monthly mortgage is ${(current_price * 0.051) / 12:.6f}.')

```

Explanation:

The program takes two integer inputs, representing the current house price and last month's price. It then uses a formatted string to output a summary, including the current price, the change since last month (calculated by subtracting the current price from last month's price), and the estimated monthly mortgage computed using the given formula. The use of f-strings in Python allows for concise and readable code, embedding expressions directly within the string.

The map function is employed to convert the input values into integers. The program calculates the change in price by subtracting the current price from last month's price. To ensure precise spacing and formatting, the f-string includes the required text and variable values in a structured manner. The estimated monthly mortgage is calculated using the provided formula and formatted as a floating-point value with six decimal places.

The code adheres to the assignment's emphasis on precision in spacing, punctuation, and newlines. By using f-strings and the specified formula, the program produces the required output with clarity and accuracy.

Final answer:

The question involves creating an algorithm to generate permutations of a given string without altering the positions of uppercase alphabets, a problem suitable for Computers and Technology at the college level.

Explanation:

The task requires generating all permutations of a given string while maintaining the original positions of the uppercase alphabets. This is typically a problem that can be approached algorithmically, falling under the category of Computers and Technology. To solve it, you would need to find permutations of the lowercase letters only and then insert them back into the string at the positions not occupied by uppercase letters.

One way to achieve this is to extract all lowercase letters and use a permutation algorithm, such as Heap's algorithm, to generate all permutations while the uppercase letters act as anchors, holding their respective positions fixed. As each permutation of the lowercase letters is generated, it's interlaced with the uppercase ones to construct a full-string permutation that meets the condition. This process is repeated until all permutations of the lowercase characters are exhausted.

Implement the make change algorithm you designed in the previous problem. Your program should read a text file "data.txt" where each line in "data.txt" contains three values c, k and n. Please make sure you take your input in the specified order c, k and n. For example, a line in "data.txt" may look like the following:3 4 38

where c = 3,k = 4,n = 38. That is, the set of denominations is {30,31,32,33,34} = {1,3,9,27,81}, and we would like to make change for n = 38. The file "data.txt" may include multiple lines like above.

The output will be written to a file called "change.txt", where the output corresponding to each input line contains a few lines. Each line has two numbers, where the first number denotes a de- nomination and the second number represents the cardinality of that denomination in the solution. For example, for the above input line ‘3 4 38’, the optimal solution is the multiset {27, 9, 1, 1}, and the output in the file "change.txt" is as follows:

27 1 91 12

which means the solution contains 1 coin of denomination 27, one coin of 9 and two coins of denomination

What is the largest numeric value that could be represented with three bytes if each digit were encoded using one ASCII pattern per byte? What if binary notation were used?

Answers

The largest numeric value that can be represented in 3 bytes is 224

Explanation:

commonly, to represent a 999 number, 10 bits are used.But with 3 bytes, it can save or store integer with the range from 0 to 224-1 in the 24 bits. (3 * 8 bits =24 bits).Then the binary notation is used for encoded numeric data in order to store in the computer storage device.

Final answer:

The largest value with three bytes using ASCII is 127127127, but for practical numerical storage in binary notation, the largest value with three bytes is 16777215, represented as 11111111 11111111 11111111 in binary.

Explanation:

The largest numeric value that could be represented with three bytes using one ASCII pattern per byte depends on the ASCII printable characters range. ASCII characters are represented within the range of 0 to 127, therefore in three bytes, the largest decimal values you could represent would be 127127127. However, this is not typically how numeric values are stored.

When using binary notation, each byte consists of 8 bits, and the maximum value for each bit is 1. Therefore, the largest value in a single byte is 11111111, which is 255 in decimal. Hence, in three bytes, the largest decimal number that can be stored is 16777215 (which is 11111111 11111111 11111111 in binary).

Write a program that keeps asking the user for new values to be added to a list until the user enters 'exit' ('exit' should NOT be added to the list). These values entered by the user are added to a list we call 'initial_list'. Then write a function that takes this initial_list as input and returns another list with 3 copies of every value in the initial_list. Finally, inside main(), print out all of the values in the new list. For example: Input: Enter value to be added to list: a Enter value to be added to list: b Enter value to be added to list: c Enter value to be added to list: exit Output: a b c a b c a b

Answers

Answer:

def new_list_function(initial_list):

   new_list = initial_list*3

   return new_list

def main():

   initial_list = []

   while True:

     item = input("Enter value to be added to list: ")

     item = item.rstrip()

     if item.lower() == "exit" and "EXIT" and "Exit":

         break

     initial_list.append(item)

     new_list = new_list_function(initial_list)

   for item in new_list:

     print(item)

Create an E-R Diagram for the following:An art museum owns a large volume of artworks. Each artwork is described by an item Id (identifier), title, type, and size; size is further composed of height, width, and weight. A work of art is developed by an artist, but the artist for some works is unknown. An artist is described by an artist ID (identifier), name, date of birth, and date of death (which is null for still living artists). Notice that the name of the artist is a composite attribute, composed of first, last and preferred names and it cannot be empty. The artist DOB is also required). Data about both artists of works currently owned by the museum and artists that have otherwise been featured in the museum are kept in the database. At any point in time, a work of art is either on display at the museum, held in storage, away from the museum as part of a traveling show, or on loan to another gallery. If on display at the museum, a work of art is also described by its location within the museum. A traveling show is described by a show ID (identifier), and the start and end dates of the show. Many of the museum works may be part of a given show, and only active shows with at least one museum work of art need be represented in the database. Every show may be visiting multiple cities and therefore has a schedule associated with it, listing the city visited, the start and end dates and the contact phone number. There may be more than 1 contact phone numbers and all the attributes are required. Notice that there is only one schedule associated with each show but the same schedule can be used more than once for shows that are travelling together. Only schedules that have been used for shows are stored in the database. Finally, another gallery is described by a gallery ID (identifier), name, and city. The museum wants to retain a complete history of loaning a work of art to other galleries, and each time a work is loaned, the museum wants to know the date the work was loaned and the date it was returned. As you develop the ERD for this problem, follow good data naming guidelines.

Answers

Write code that prints: Ready! firstNumber ... 2 1 Run! Your code should contain a for loop. Print a newline after each number and after each line of text Ex: firstNumber = 3 outputs:

Answers

Final answer:

The task requires a Python code using a for loop to count down from a specified starting number, printing 'Ready!', each number on a new line, and 'Run!' at the end.

Explanation:

To write code that counts down from a given number and prints 'Ready!', followed by each number, and ending with 'Run!', we can use a for loop. Here is a sample Python code snippet that accomplishes this:

firstNumber = 3
print('Ready!')
for num in range(firstNumber, 0, -1):
   print(num)
   print('\n')
print('Run!')

This code starts by printing 'Ready!', then it enters a for loop that counts down from firstNumber to 1, printing each number followed by a newline. Finally, it prints 'Run!' after exiting the loop. Remember to replace firstNumber with the actual starting number you wish to count down from.
