Fun with Numbers Instructions: Ask the user for 2 integer numbers, then use those values to calculate: The sum of the 2 numbers  Difference between them  The product   The integer based division (no decimal point)  The remainder of the integer division First i looked for math operations with python and found this youtube video: Then i had some trouble with my variables because they were strings and i converted them to integers using int (), but after that minor struggle the program runned just fine. I'll leave a link to my code: https://www.dropbox.com/s/udfbrwf619a5n0b/Wsq03.py?dl=0

Network and Wireless Security

"Wireless networks are inherently insecure" (Lawrence, 2018). "Wireless network security primarily protects a wireless network from unauthorized and malicious access attempts". (Technopedia, 2018) There are 3 indispensable wireless security protocols: WEP, WPA, and WPA2, each with their own strengths, and weaknesses. In addition to preventing uninvited guests from connecting to your wireless network, wireless security protocols encrypt your private data as it is being transmitted over the airwaves. To further understand these protocols we need to define each one of them: Wired Equivalent Privacy (WEP): The original encryption protocol developed for wireless networks. As its name implies, WEP was designed to provide the same level of security as wired networks. However, WEP has many well-known security flaws, is difficult to configure, and is easily broken. Wi-Fi Protected Access (WPA): Introduced as an interim security enhancement over WEP while the 802.11i wire...

User interface design and software verification and validation User interface design  is the  design  of  user interfaces  for machines and software with the focus on maximizing usability and the  user  experience.  focuses on anticipating what users might need to do and ensuring that the interface has elements that are easy to access, understand, and use to facilitate those actions. UI brings together concepts from  interaction design ,  visual design , and  information architecture . They are 19 principles of  User Interface Design: Clarity is job  Interfaces exist to enable interaction Conserve attention at all costs Keep users in control Direct manipulation is best One primary action per screen Keep secondary actions secondary Provide a natural next step Appearance follows behavior Consistency matters Strong visual hierarchies work best Smart organization reduces cognitive load Highlight, don't...
