Expert Solution & Answer
Chapter 17, Problem 17.1E
Explanation of Solution
Scalability:
Scalability is nothing but an attribute that has the ability to grow and administer increased demand in an organization or network or software.
In other words, when the network, system, software or an organization is ready to handle,
- Influx of demand
- Increased productivity
- Changing trends
Differences between scaling up and scaling out with respect to scalability:
| Scaling up | Scaling out |
| It is the process of replacing resources in the system with more powerful resources | It is the process of adding new resources to an existing system. |
| It is also called as concurrent | It is also called as distributed programming. |
| It is costlier than scaling out. | It is cost effective. |
| Example: If the computer runs out of resources, it is not necessary to make changes with the computer instead, the memory can be increased. | Example: Adding extra web server in order to work along with the existing one. |

John's query willreturn the same results all three times it is executed as they are run in the same session.
John's queries run at10:16 and10:20 produce the same result, which is different from the one at 10:14
John's query run at 10:16 waits until 10:18 to produce results, waiting for the commit to happen.

Word FrequencyWrite a program that reads the contents of a text file. The program should create a dictio-nary in which the keys are the individual words found in the file and the values are the number of times each word appears. For example, if the word “the” appears 128 times, the dictionary would contain an element with 'the' as the key and 128 as the value. The program should either display the frequency of each word or create a second file containing a list of each word and its frequency.arrow_forward3.) File Encryption and DecryptionWrite a program that uses a dictionary to assign “codes” to each letter of the alphabet. For example: codes = { ‘A’ : ‘%’, ‘a’ : ‘9’, ‘B’ : ‘@’, ‘b’ : ‘#’, etc . . .}Using this example, the letter A would be assigned the symbol %, the letter a would be assigned the number 9, the letter B would be assigned the symbol @, and so forth. The program should open a specified text file, read its contents, then use the dictionary to write an encrypted version of the file’s contents to a second file. Each character in the second file should contain the code for the corresponding character in the first file. Write a second program that opens an encrypted file and displays its decrypted contents on the screen.arrow_forward

Testing Hint: We be exact on the format of the number when testing this method. Make sure you think about how to convert 33 to 033 or numbers like that when setting your string format.

Here are some notes to help you work the problem: • strcpy(char *dst, char *src) copies the string at address src (including the terminating '\0' character) to address dst. It does not check the size of the destination buffer.
