2023 A large fast food chain unveiled a new touch screen register for its franchises Each | Assignment Collections

 A large, fast-food chain unveiled a new touch screen register for  its franchises. Each cashier was assigned a user id and password  combination to log in to the register. The system allowed the incorrect  password to be entered four (4) times before the register would lock and  require a manager to unlock it with a key card. To prevent unauthorized  access, the registers would lock after three (3) minutes if the screen  was not touched. When the register locked, only the cashier who was  logged in prior to it locking could unlock it without a system restart.  After  a few days in operation, restaurant managers started complaining about  the amount of time they were spending unlocking the registers. Some  cashiers were forgetting their user Id and password, so other cashiers  would log in for them. It also seemed that the button layout made it  easy for the cashiers to key in the incorrect password. The managers  also complained that cashiers would leave for a break or end their shift  and forget to log out of the locked register. The managers would have  to reboot the system, a three to five (3-5) minute process in order for  the next cashier to log in. Additionally, managers noticed that grease  was building up on the touch screens, making them less responsive.   Write a five to eight (5-8) page paper in which you:    

  1. Analyze the new system and determine the design issues with this new system.
  2. Describe how you would correct the design issues with the system to make the restaurant managers happy.
  3. Create a design plan that:  
    1. Lists and explains the tasks associated with improving this interface. 
    2. Contains at least six (6) tasks.
    3. Includes realistic time estimates for each task to be completed.
    4. Analyzes the development of the system in your plan.
    5. Analyzes the testing of the system in your plan.
    6. Analyzes the implementation of the system in your plan.  
  4. Examine  how this system balanced security and usability, and explain the  challenges of incorporating system security and system usability into a  design.
  5. Suggest changes that could be made to the security of  this system to still meet security objectives but make the system more  usable.
  6. Use Microsoft Visio or an open source alternative, Dia,  to create a graphical representation of your proposed interface. Note:  The graphically depicted solution is not included in the required page  length.
  7. Use at least four (4) quality resources in this  assignment. Note: Wikipedia and similar Websites do not qualify as  quality resources.

2023 1 Usability is a website design term that describes how easy and appealing a website is to visitors Good usability | Assignment Collections

Computer Science 2023 disscussion reply to the question asked from students minimum words count 50 each

2023 1 Usability is a website design term that describes how easy and appealing a website is to visitors Good usability | Assignment Collections

1: Usability is a website design term that describes how easy and appealing a website is to visitors. Good usability requires that the website is easy to navigate, has an attractive layout, and is useful to the visitors. Usability is an important part in the design and development of a good website. In today’s society the web has become a tool for information retrieval, and it can be difficult sometimes to find information, which is another reason why usability is important.  An unattractive or poorly built site will do more to hurt your business than to help it. A site must be visually appealing, polished and professional. An attractive site is far more likely to generate a positive impression and keep visitors on your site once they arrive. A simple way to increase visual appeal is to use high quality photography. Graphics are important, as they lend visual variety and appeal to an otherwise boring page of text.

 

2:Using the library, research an article that describes the importance of usability when designing a website. Provide a summary of the article and explain the qualities and importance of effective design.

 

3:CSS stands for Cascading Style Sheets, and it describes how HTML elements are able to be displayed on screen, and in other media. CSS is the key to web design, because it controls the color, layout, font and decorations. It’s designed to make life easier for designers. Any website that use CSS is unique because it’s their own creation. I think Google use CSS to enhance their website appearance, because of the different colors they use, and the type of font they use.

 

IT 240

4: Firewalls prevent outside activity and monitor incoming and outgoing activity to ensure unwanted “guests” or tag-a-longs do not gain access to the network. Windows has its own firewall that can be configured to the user’s needs. Norton also has a firewall that helps secure the network. It is very important to maintain security on any network (including LAN) to monitor threats, take care of any virus that may be threatening or damaging the network, and to make sure that only the approved users have access to the network. The use of firewalls does help prevent attacks from malware programs and bugs or viruses. Personally I use Norton because I feel it is more secure than the free versions such as Ad aware and AVG. Of course that is just my opinion based off of my experiences. My father in law uses the free versions of anti virus protections and firewalls and has had a lot of troubles with viruses attacking his computers. He also uses a LAN and it seems when his laptop gets attacked, so does the other computers and laptops linked to the network.

 

5:What roles do firewalls and proxy servers play in network security? What is the importance of maintaining security on a LAN? Provide examples to support your answer.

 

6:Write a 200- to 300-word short-answer response to the following:


What are some current computer threats? Describe the nature of the threat and the potential repercussions it could have for a network. The following are some suggested sites to begin your search: http://www.mcafee.com/us/ http://www.microsoft.com http://www.cnet.com.

Calculus Chapter 2

 Read the bottom of p.160 through the top of p. 161. Now take a road trip.  If you don’t drive, ride with a friend, or ride the bus.  Think about what you are feeling as the vehicle starts, speeds up, moves, slows down, and stops.  Considering the position of the vehicle as the function, explain what you notice in terms of the function and its first, second, and third derivatives.  How do you measure each of these, both by using the vehicle’s instruments and by what you feel acting on your body?   Note:  Be safe!  Obey speed limits and other laws of the road.  You can test these phenomena without driving fast.   Once you have posted, respond to one other post. Do not focus on length, but instead focus on clear and original thoughts.  As always, your work must be your own.

Computer Science 2023 Mobile Application – Discussion

2023 Among one of many reasons to target the Android platform first and foremost is cost | Assignment Collections

Among one of many reasons to target the Android platform, first and foremost is cost. On average you can get an Android smartphone for a fraction of the cost of an iPhone. They may not have commensurate features, but thrift is a major component for new smartphone buyers. Next is flexibility.    Developers can often find on cheap and imported Android devices a version of Google Play that is maintained by the manufacturer.  Developers should develop as if they expect their app to be available to all Android devices.

  • Besides cost, why should mobile app developers target the Android platform?
  • Why is Android competition to itself?
  • Describe key ingredients needed to create mobile applications on the iOS platform.
