| A distributed database stores a logically associated database across more than one physically independent site which is linked through |
Distributed processing shares the logical processing of a database across more than one independent site which is linked through network. |
| It needs the distributed processing because data is distributed at multiple sites... |

Alphabetic Telephone Number TranslatorMany companies use telephone numbers like 555-GET-FOOD so the number is easier for their customers to remember. On a standard telephone, the alphabetic letters are mapped to numbers in the following fashion:
A, B, and C = 2
D, E, and F = 3
G, H, and I = 4
J, K, and L = 5
M, N, and O = 6
P, Q, R, and S = 7
T, U, and V = 8
W, X, Y, and Z = 9
Write a program that asks the user to enter a 10-character telephone number in the format XXX-XXX-XXXX. The application should display the telephone number with any alphabetic characters that appeared in the original translated to their numeric equivalent. For example, if the user enters 555-GET-FOOD, the application should display 555-438-3663.

- When the FCC added Color Television to the Industry Standards, they went with the system developed in the 1940s by Peter Goldman for CBS. Question 15 options: True False Part of the reason that many critics disliked 1950s gameshows was the fact that gameshows offered one of the few opportunities to see unscripted interactions with "real" (average/non-famous) people on television. Question 16 options: True False The Andy Griffith Show is an example of the "rural revival" shows that become enormously popular on 1960s American television. Question 19 options: True False During the Network Era, the hours before primetime each day were exclusively devoted to locally-produced programming, not programming dictated by an affiliate station's parent network. Question 20 options: True Falsearrow_forwardAlthough color television was not added to the industry standard until 1956, CBS had been broadcasting selected special events in color as early as 1950. Question 1 options: True False Two key factors in creating the Network Era of American television were the FCC licensing freeze and ______________. Question 4 options: The Quiz Show Scandals Habitual Viewing Operation Frontal Lobes Drop-In Viewing Least Objectionable Programming was designed to embrace the public service-oriented vision of using television to elevate mass culture and enrich viewers. Question 6 options: True False By the end of the 1950s, all three remaining networks (NBC, CBS, & ABC) were broadcasting their entire nightly programming schedule in full color. Question 9 options: True Falsearrow_forward7. See the code below and solve the following. public class Test { public static void main(String[] args) { int result = 0; } result = fn(2,3); System.out.println("The result is: + result); // fn(x, 1) = x // fn(x, y) = fn(x, y-1) + 2, when y>1 public static int fn(int x, int y) { if (x <= 1) return x; else return fn(x, y-1) + 2; } } 7-1. This program has a bug that leads to infinite recursion. Modify fn(int x, int y) method to fix the problem. (2 point) 7-2. Manually trace the recursive call, fn(2,3) and show the output (step by step). (2 point) 7-3. Can you identify the Base Case in recursive method fn(int x, int y)? (1 point)arrow_forward

This program has a compile error, and the message is “Unhandled exception type FileNotFoundException". How do you fix this error? (1 point) 6-2. Is FileNotFoundException a checked exception or an unchecked exception? (1 point) 6-3. What is the difference between checked exception and unchecked exception? (1 point) 6-4. Please complete the above program by reading all data from temp.dat and print the data to the standard output (monitor) by using System.out.print, System.out.println or System.out.printf method. (2 points)arrow_forwardWrite a program that reads a list of integers from input and determines if the list is a palindrome (values are identical from first to last and last to first). The input begins with an integer indicating the length of the list that follows. Assume the list will contain a maximum of 20 integers. Output "yes" if the list is a palindrome and "no" otherwise. The output ends with a newline. Hints: - use a for loop to populate the array based on the specified size (the first number entered) - use a for loop to check first value with last value, second value with second from end, etc. - if the values do not match, set a Boolean variable to flag which statement to output (yes or no) Ex: If the input is (remember to include spaces between the numbers): 6 1 5 9 9 5 1 the output is: yes Ex: If the input is: 5 1 2 3 4 5 the output is: C++ codingarrow_forwardDesign and draw a high-level "as-is" process diagram that illustrates a current process related to a product or service offered through the SSDCI.gov database.arrow_forward
