Program Plan Intro
“Philly311” project:
“Philly311” is the non-emergency contact centre in the city Philadelphia. The centre is to help people in issue requests like broken traffic signals, and receive the complaints.
Explanation of Solution
Contribution of people:
- The citizens of Philadelphia use this helping centre from the beginning. Users of Philly311 are highly recommend is to other people to solve their issues. Philly311 hired local employees and transfers which leads to effective employment.
- The issues of people are also posted by social Medias like twitter, Facebook. So, the followers of this media increased by 360% from the beginning.
Contribution of organization:
- Team implementation is important for the service. The organization plays a vital role in project development...

Question 2 (25 pts)
A sequential circuit with two D flip-flops A and B, two inputs x and y, and one output z is
specified by the following next-state and output equations:
A(t + 1) = xy' + xB
B(t + 1) = xA + xB'
z = A
a. Draw the logic diagram of the circuit. (5 pts)
b. List the state table for the sequential circuit. (10 pts)
c. Draw the corresponding state diagram. (10 pts)
5. 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.
3.) 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.

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. You will need to know the hex values of the following characters:arrow_forwardA ROP (Return-Oriented Programming) attack can be used to execute arbitrary instructions by chaining together small pieces of code called "gadgets." Your goal is to create a stack layout for a ROP attack that calls a function located at '0x4018bd3'.

- Node.js, Express.js, MongoDB, and Mongoose: Create, Read, Update, and Delete Operations There is a program similar to this assignment given as the last example, CRUD, in the lecture notes for the week that discusses the introduction to MongoDB. Basically, you need to adapt this example program to the data given in this assignment. This program will take more time that previous assignments. So, hopefully you'll start early and you've kept to the schedule in terms of reading the lecture notes. You can use compass if you want to create this database. Or, when your connection string in the model runs it will create the database for you if one does not yet exist. So, ⚫ create a Mongoose model based on the info given below. The index.html page is given in the same folder as these notes. • When you successfully run index.js and instantiate the model, your database is created. • Once the database is created, you need to perfect the addCar route so you can add data using the index.html page. •…arrow_forward1. Enabled with SSL, HTTPS protocol is widely used to provide secure Web services to Web users using Web browsers on the Internet. How is a secure communication channel established at the start of communication between a Web server running HTTPS and a Web browser? Consider the following threats to Web security and how each of these threats is countered by a particular feature of SSL. Man-in-the-middle attack: An attacker interposes during key exchange, acting as the client to the server and as the server to the client. Password sniffing: Passwords in HTTP or other application traffic are “eavesdropped.” SYN flooding: An attacker sends TCP SYN messages to request a connection but does not respond to the final message to establish the connection fully. The attacked TCP module typically leaves the “half-open” connection around for a few minutes. Repeated SYN messages can clog the TCP module.arrow_forwardSQL Injection on UPDATE Statement for educational purpose only Based on the information below how do i update this code in order to update the emplyees field, eg admin nickname, email,address, phone number etc? ' ; UPDATE users SET NickName='Hacked' WHERE role='admin' -- If a SQL injection vulnerability happens to an UPDATE statement, the damage will be more severe, because attackers can use the vulnerability to modify databases. In our Employee Management application, there is an Edit Profile page (Figure 2) that allows employees to update their profile information, including nickname, email, address, phone number, and password. To go to this page, employees need to log in first. When employees update their information through the Edit Profile page, the following SQL UPDATE query will be executed. The PHP code implemented in unsafe edit backend.php file is used to update employee’s profile information. The PHP file is located in the /var/www/SQLInjection directory.arrow_forward
